Snap packages have become increasingly popular since they provide an easy way to install software on any Linux distribution. This a brief overview of the Snap package format.

NOTE TO ARCH USERS: When I installed snapd I meant to mention this. If If AppArmor isn't enabled in your system then all snaps will run in devel mode which mean they will have same, unrestricted access to your system as apps installed from Arch Linux repositories.

$ systemctl enable --now apparmor.service
$ systemctl enable --now snapd.apparmor.service

Snap is a software Package manager|packaging and Software deployment|deployment system developed by Canonical (company)|Canonical for the Linux operating system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions and allow Upstream (software development)|upstream software developers to distribute their applications directly to users. Snaps are self-contained applications running in a sandbox with mediated access to the host system. Snap was originally released for Cloud computing|cloud applications{{Cite web|last1=Shuttleworth|first1=Mark|date=9 December 2014|title=Announcing Ubuntu Core, with snappy transactional updates!|url=https://www.markshuttleworth.com/archives/1434|access-date=2020-08-07}} but was later ported to work for Internet of things|Internet of Things devices{{Cite web|title=Ubuntu Core and Snappy [LWN.net]|url=https://lwn.net/Articles/630660/|access-date=2020-08-08|website=lwn.net}}{{Cite web|title=Canonical unveils Snappy Ubuntu Core, a lightweight operating system for your home - ExtremeTech|url=https://www.extremetech.com/mobile/197801-canonical-unveils-snappy-ubuntu-core-a-lightweight-operating-system-for-your-home|access-date=2020-08-08|website=www.extremetech.com}} and desktop{{Cite web|last=Bhartiya|first=Swapnil|date=2015-04-27|title=Is Ubuntu moving away from .deb packages?

Functionality

=Snap Store

=
The Snap Store allows developers to publish their applications directly to users.{{Cite web|last=S|first=James|last2=August 6|first2=ers in Software on|last3=2019|last4=Pst|first4=8:53 Am|title=Why Canonical views the Snap ecosystem as a compelling distribution-agnostic solution|url=https://www.techrepublic.com/article/why-canonical-views-the-snap-ecosystem-as-a-compelling-distribution-agnostic-solution/|access-date=2020-08-05|website=TechRepublic|language=en}} With traditional Linux package management approaches like Advanced Packaging Tool|APT or Yellowdog Updater, Modified|YUM, the applications are packaged and distributed as part of the operating system. This creates a delay between application development and its deployment for end-users.[https://bugs.launchpad.net/ubuntu/+bug/578045 Upgrading packaged Ubuntu application unreasonably involves upgrading entire OS Bug #578045] on bugs.launchpad.net/ubuntu by John King (2010-05-10)[https://www.youtube.com/watch?v=5PmHRSeA2c8&t=581 Linus Torvalds on the problems of distro packaging] Linus Torvalds on DebConf 2014 In contrast, application developers can publish their applications in the Snap Store and get them directly to users without any intervention from distribution maintainers.

All apps uploaded to the Snap Store undergo automatic testing, including a malware scan. However, Snap apps do not receive the same level of verification as software in the regular Ubuntu archives. In one case in May 2018, two applications by the same developer were found to contain a cryptocurrency miner which ran in the background during application execution. When this issue was found, Canonical removed the applications from the Snap Store and transferred ownership of the Snaps to a trusted third-party which re-published the Snaps without the miner present.{{Cite web|title=How Canonical Is Improving Ubuntu Linux Security|url=https://www.eweek.com/security/how-canonical-is-improving-ubuntu-linux-security|access-date=2020-08-08|website=eWEEK}}{{Cite web|date=2018-05-13|title=Malware Found on the Ubuntu Snap Store|url=https://www.omgubuntu.co.uk/2018/05/ubuntu-snap-malware|access-date=2020-07-19|website=OMG!

Because packages in the Snap Store are maintained by developers themselves, distribution maintainers cannot ensure packages meet quality standards and are timely updated. In one case, Microsoft left an outdated version of Skype in the Snapcraft store for over a year.{{Cite web|date=2019-07-09|title=Hey Microsoft, why is the Skype Snap app hopelessly outdated?|url=https://www.omgubuntu.co.uk/2019/07/skype-snap-app-no-update|access-date=2020-07-19|website=OMG! Ubuntu!|language=en-GB}}

Although the Snap Store by Canonical is currently the only existing store for snaps, Snap itself can be used without a store. Snap packages can be obtained from any source, including the website of a developer. Red Hat employee Adam Williamson and Linux Mint project lead Clement Lefebre have criticized Canonical for keeping some server side parts of the Snap Store closed-source.{{Cite web|title=On Snappy and Flatpak: business as usual in the Canonical propaganda department|url=https://www.happyassassin.net/2016/06/16/on-snappy-and-flatpak-business-as-usual-in-the-canonical-propaganda-department/|access-date=June 5, 2019|website=Happyassassin}} Clement states that this creates a conflict of interest which harms the neutrality of Snap given that Canonical develops Ubuntu.{{Cite web|title=Monthly News – June 2019|url=https://blog.linuxmint.com/?p=3766|access-date=October 23, 2019|website=blog.linuxmint.com}}

=Universal Linux packages

=
Snaps are Portable application|self-contained packages that work across a range of Linux distributions. This is unlike traditional Linux package management approaches, which require specifically adapted packages for each Linux distribution.{{Cite web|last=June 21|first=Jack Wallen in Open Source on|last2=2016|last3=Pst|first3=8:13 Am|title=Canonical changes the game by announcing universal snap packages|url=https://www.techrepublic.com/article/canonical-changes-the-game-by-announcing-universal-snap-packages/|access-date=2020-08-08|website=TechRepublic|language=en}}{{Cite web|last=Kepes|first=Ben|date=2016-06-14|title=Snap!

The snap file format is a single compressed File system|filesystem using the squashfs|SquashFS format with the extension .snap. This filesystem contains the application, libraries it depends on, and declarative metadata. This metadata is interpreted by snapd to set up an appropriately shaped secure Sandbox_(computer_security)|sandbox for that application. After installation, the snap is mounted by the host operating system and decompressed on the fly when the files are used.{{Cite web|last=ReadySpace|date=2019-11-14|title=A technical comparison between the snap and the Flatpak formats|url=https://readyspace.co.id/en/a-technical-comparison-between-the-snap-and-the-flatpak-formats/|access-date=2020-08-05|website=ReadySpace Indonesia|language=en-US}}{{Cite web|last=McKay|first=Dave|title=How to Work with Snap Packages on Linux|url=https://www.howtogeek.com/660193/how-to-work-with-snap-packages-on-linux/|access-date=2020-08-05|website=How-To Geek|language=en-US}} Although this has the advantage that snaps use less disk space, it also means some large applications start slower.{{Cite web|date=2019-10-29|title=Squashfs performance effect on snap startup time|url=https://forum.snapcraft.io/t/squashfs-performance-effect-on-snap-startup-time/13920|access-date=2020-08-05|website=snapcraft.io|language=en-US}}

A significant difference between Snap and other universal Linux packaging formats such as Flatpak is that Snap supports any class of Linux application such as desktop applications, server tools, IoT apps and even system services such as the printer driver stack.{{Cite web|date=2018-03-09|title=Call for testing: OpenPrinting's printing-stack-snap (Printing in a Snap)|url=https://forum.snapcraft.io/t/call-for-testing-openprintings-printing-stack-snap-printing-in-a-snap/4406|access-date=2020-08-05|website=snapcraft.io|language=en-US}}{{cite web|title=Canonical unveils 6th LTS release of Ubuntu with 16.04|url=https://insights.ubuntu.com/2016/04/20/canonical-unveils-6th-lts-release-of-ubuntu-with-16-04/|accessdate=22 April 2016|website=Ubuntu Insights|publisher=Canonical (company)|Canonical Ltd.}} As a result of this, Snap relies on systemd for features such as running socket-activated system services in a Snap.{{cite web|title=Services and daemons|url=https://snapcraft.io/docs/services-and-daemons}} This causes Snap to only work on distributions that use this Init|init system.{{Cite web|title=WSL2- Ubuntu 20.04 Snap store doesn't work due to systemd dependency · Issue #5126 · microsoft/WSL|url=https://github.com/microsoft/WSL/issues/5126|access-date=2020-08-07|website=GitHub|language=en}}

=Configurable sandbox

=
Applications in a Snap run in a container with limited access to the host system. Using Interfaces, Users can give an application mediated access to additional features of the host such as recording audio, accessing USB devices and recording video.{{Cite web|title=Supported interfaces {{!}} Snapcraft documentation|url=https://snapcraft.io/docs/supported-interfaces|access-date=2020-08-05|website=Snapcraft|language=en}}{{Cite web|last=ReadySpace|date=2019-06-06|title=Snapcraft confinement & interfaces|url=https://readyspace.com.cn/snapcraft-confinement-interfaces/|access-date=2020-08-05|website=ReadySpace China|language=zh-hans}}{{Cite web|last=ReadySpace|date=2018-11-02|title=A guide to snap permissions and interfaces|url=https://readyspace.com.hk/a-guide-to-snap-permissions-and-interfaces/|access-date=2020-08-05|website=ReadySpace Hong Kong|language=en-US}} These interfaces mediate regular Linux API's so that applications can function in the sandbox without needing to be rewritten. Desktop applications can also use the XDG Desktop Portals, a standardized API originally created by the Flatpak project to give sandboxed desktop applications access to host resources.{{Cite web|title=Flatpak's XDG-Desktop-Portal Adds Initial Support For Snaps - Phoronix|url=https://www.phoronix.com/scan.php?page=news_item&px=XDG-Desktop-Portal-Snapped|access-date=2020-08-05|website=www.phoronix.com}}{{Cite web|title=Desktop Integration — Flatpak documentation|url=https://docs.flatpak.org/en/latest/desktop-integration.html?highlight=portals#portals|access-date=2020-08-05|website=docs.flatpak.org}} These portals often provide a better user experience compared to the native Linux API's because they prompt the user for permission to resources such as a webcam at the time the application uses them. The downside is that applications and toolkits need to be rewritten in order to use these newer API's.

The Snap sandbox also supports sharing data and Unix domain socket|Unix sockets between Snaps.{{Cite web|title=The content interface|url=https://snapcraft.io/docs/content-interface|access-date=2020-04-29|website=Snapcraft|language=en}} This is often used to share common libraries and application frameworks between Snaps to reduce the size of Snaps by avoiding duplication.{{Cite web|date=2017-06-11|title=Snappy Is Finally Doing Something About Super Large App Sizes|url=https://www.omgubuntu.co.uk/2017/06/gnome-platform-snap-development|access-date=2020-08-07|website=OMG!

The Snap sandbox heavily relies on the AppArmor Linux Security Module from the upstream Linux kernel. Because only one Linux Security Modules|Linux Security Module (LSM) can be active at the same time, the Snap sandbox is much less secure when another LSM is enabled. As a result, on distributions such as Fedora which enable Security-Enhanced Linux|SELinux by default, the Snap sandbox is heavily degraded. Although Canonical is working with many other developers and companies to make it possible for multiple LSM's to run at the same time, this solution is still a long time away.{{Cite web|date=2020-07-11|title=How Are SNAPS claiming to have no internet plug regulated?|url=https://forum.snapcraft.io/t/how-are-snaps-claiming-to-have-no-internet-plug-regulated/18755/25|access-date=2020-08-06|website=snapcraft.io|language=en-US}}{{Cite web|title=LSM stacking and the future [LWN.net]|url=https://lwn.net/Articles/804906/|access-date=2020-08-06|website=lwn.net}}{{Cite web|last=Johansen|first=John|date=3 February 2019|title=Containers with Different Security Modules|url=https://archive.fosdem.org/2019/schedule/event/containers_lsm/|url-status=live|archive-url=|archive-date=|access-date=|website=}}

The Snap sandbox prevents snapped desktop applications from accessing the themes of the host operating system to prevent compatibility issues. In order for Snaps to use a theme, it also needs to be packaged in a separate Snap. Many popular themes are packaged by the Snap developers{{Cite web|date=2020-02-21|title=How to use the system GTK theme via the gtk-common-themes snap|url=https://forum.snapcraft.io/t/how-to-use-the-system-gtk-theme-via-the-gtk-common-themes-snap/6235|access-date=2020-08-06|website=snapcraft.io|language=en-US}} but some themes are not supported yet{{Cite web|title=Kubuntu 20.04 LTS Review {{!}} ORDINATECHNIC|url=https://www.ordinatechnic.com/distribution-reviews/Kubuntu/kubuntu-2004-lts-review|access-date=2020-07-19|website=www.ordinatechnic.com}} and uncommon themes have to be installed manually.

Publishers can release and update multiple versions of their software in parallel using channels. Each channel has a specific track and risk, which indicate the version and stability of the software released on that channel. When installing an application, Snap defaults to using the latest/stable channel, which will automatically update to new major releases of the software when they become available. Publishers can create additional channels to give users the possibility to stick to specific major releases of their software. For example, a 2.0/stable channel would allow users to stick to the 2.0 version of the software and only get minor updates without the risk of backwards incompatible changes. When the publisher releases a new major version in a new channel, users can manually update to the next version when they choose.{{Cite web|title=Controlling snap releases with channels, tracks and branches – Part 1|url=https://ubuntu.com/blog/controlling-snap-releases-with-channels-tracks-and-branches-part-1|access-date=2020-08-07|website=Ubuntu|language=en}}{{Cite web|title=Controlling snap releases with channels, tracks and branches – Part 2|url=https://ubuntu.com/blog/controlling-snap-releases-with-channels-tracks-and-branches-part-2|access-date=2020-08-07|website=Ubuntu|language=en}}{{Cite web|last=Prakash|first=Abhishek|title=Using Snap Packages In Ubuntu & Other Linux [Complete Guide]|url=https://itsfoss.com/use-snap-packages-ubuntu-16-04/|access-date=2020-08-07|language=en-US}}

Although automatic updates cannot be turned off, there are many ways to configure updates to suit particular needs. User can choose to remain on a specific major version of the software by specifying the channel, they can configure the update interval to have time to manually check updates, and they can hold updates for up to 60 days. In addition, updates are also automatically disabled on metered connections.{{Cite web|last=Logix|title=How To Change Snap Refresh (Update) Schedule|url=https://www.linuxuprising.com/2019/07/how-to-change-snap-refresh-update.html|access-date=2020-08-07|website=Linux Uprising Blog|language=en-us}}{{Cite web|last=Pope|first=Alan|date=3 March 2020|title=Controlling Snap Updates|url=https://www.youtube.com/watch?v=gVZOBgTDJWc|url-status=live|archive-url=|archive-date=|access-date=|website=}} Even with these controls, a number of users have voiced their complaints about the lack of an option to turn automatic updates completely off.{{Cite web|title=Disabling automatic refresh for snap from store|url=https://forum.snapcraft.io/t/disabling-automatic-refresh-for-snap-from-store/707|access-date=July 31, 2019}}

In 2019, Canonical decided to switch the Chromium web browser in future Ubuntu releases from an APT package to a Snap. They explained that Snap made it much easier to support Chromium on all supported Ubuntu releases. This allowed them to focus engineering resources on other parts of the Ubuntu desktop.{{Cite web|last=Vaughan-Nichols|first=Steven J.|title=Ubuntu opens the door to talking with Linux Mint about Snap|url=https://www.zdnet.com/article/ubuntu-opens-the-door-to-talking-with-linux-mint-about-snap/|access-date=2020-08-08|website=ZDNet|language=en}} As a result of this decision, Ubuntu derivatives such as Linux Mint had to choose between maintaining their own version of the Chromium package or switching to the snapped version of Chromium maintained by Canonical. Clement Lefebre, Linux Mint founder and project leader,{{Cite web|title=Q&A: Clement Lefebvre: The man behind Linux Mint|url=https://techworld.com.au/article/529572/q_clement_lefebvre_man_behind_linux_mint|access-date=January 7, 2020|website=techworld.com.au}} cited this as the reason why Linux Mint 20 blocks users from installing Snap.{{Cite web|last=Vaughan-Nichols|first=Steven J.|title=Linux Mint dumps Ubuntu Snap|url=https://www.zdnet.com/article/linux-mint-dumps-ubuntu-snap/|access-date=2020-08-08|website=ZDNet|language=en}} Since Snap is still available in the Linux Mint repositories, users can still install it after manually removing the restrictions.{{Cite web|last=Kumar|first=Sarvottam|date=2020-06-12|title=How To Enable Snap And Install Snap Packages On Linux Mint 20?|url=https://fossbytes.com/how-to-enable-snap-and-install-snap-packages-on-linux-mint-20/|access-date=2020-08-08|website=Fossbytes|language=en-US}}

GNOME Software removed Snap support in July of 2019, due to code quality issues, lack of integration (specifically, that the user can't tell what Snap is doing after they click "install" and that it generally ignores GNOME's settings), and the fact that it competes with the GNOME-supported Flatpak standard.{{Cite web|title=GNOME Software Moving Forward With Disabling Snap Plugin - Phoronix|url=https://www.phoronix.com/scan.php?page=news_item&px=GNOME-Software-Dropping-Snap|access-date=2020-07-19|website=www.phoronix.com}} This doesn't mean Snaps can't be installed in Fedora or other GNOME Software using distributions, only that Snap needs to be installed first. Ubuntu also used GNOME Software up to Ubuntu 20.04, and vice versa, there Flatpak support can be added.
