Snap Store

Programming in Go makes it easy to create a zip of your app that runs across Linux, without dependencies. However, end user discovery and update management remain a challenge. Snaps fill this gap, letting you distribute a Go app in an app store experience for end users.

Distributing the Linux build of your app as a zip lets you provide one download and set of instructions for all of Linux. However, end user discovery and update management remain a challenge. Snaps fill this gap, letting you wrap your existing Linux build in an app store experience for end users.

You can distribute your apps across Linux using a musl-enabled version of Rust, with all the dependencies satisfied. However, end user discovery and update management remain a challenge. Snaps fill this gap, letting you distribute a Rust app in an app store experience for end users.

The modular containment is what appealed about snaps and [we] can see it will be a lot more flexible. Starting with snaps is easy and the resources that are provided are clean and structured which aids adoption.

The Snap store provides additional exposure to our tools for many of our existing and potential users. The decision to use it came quite naturally. We believe the store will be a major software discovery tool on Linux, so the more people find out about our tools naturally and install them more easily, the better for everyone.

The Ubuntu Software application notifies me that there is an update available for Snap.When I go to Ubuntu Software and click on the update button for Snap, I receive an error message stating that"Unable to update "Snap Store": (null): cannot refresh "snap-store": snap "snap-store" has running apps (ubuntu-software), pids: 2098" .The exact error message is not displayed in the terminal.Steps I've Tried:

I have closed the Ubuntu Software application and retried the update.I attempted to manually update the Snap Store using the terminal with sudo snap refresh snap-store, but the issue persists.System Information:

so I decided to reinstall it. but when trying to do that snap store displays an error saying: 'Unable to remove "apple music electron" cannot perform the following tasks.'and when trying to remove it from the terminal it also fails when trying to "save data in automatic snapshot".

Updates to applications running under snapd cannot be applied if the app is active. The easiest / only way is to kill the mentioned app: pkill snap-store .. prefix with sudo if the app is owned by an other user than you.

Set granular permissions for users of your Dedicated Snap Store, allowing varying tiers of access and publisher rights. You can also set permissions at the snap-level, granting collaborator rights to software publishers.

When Snap was introduced Canonical promised it would never replace APT. This promise was broken. Some APT packages in the Ubuntu repositories not only install snap as a dependency but also run snap commands as root without your knowledge or consent and connect your computer to the remote proprietary store operated by Canonical.

I have a freshly installed Ubuntu system however despite doing the following command lines to add the one and only user "home" to the sudo group I cannot install software via the snap store. Can anyone please advise?

sudo snap install gimp has started the download, this is interesting, it had asked me to do it via sudo. I am not entirely clear on the point of putting home user into the sudo group if you still have to type sudo and put in the admin password too??

On ubuntu and ubuntu like systems, the root account is disabled by default for security and stability reasons. Reason why, the best and most secure way is to use a regular user like yours, that will use the sudo framework to perform administrative tasks like snap install or manage partitions with gparted.

First of all, the command displayed for the assistant is incorrect and causes some side effects. This is a rather simple fix, as I have added the `enpass` command through the Snap package, which could be shown instead. All details for this issue are found here: -snap/issues/1

Second, the browser extension does not work under `strict` confinement. This means that while the app is sandboxed, the browser extension does not function correctly. While this problem can be overcome by using `classic` confinement, which disables the sandboxing, it also voids many of the advantages of the Snap platform and isn't allowed on the store without contacting Canonical to ask for permission. The reason this problem occurs is because Enpass detects a different user is running the client and does not allow the browser to connect. You can view related logs and more details here: -snap/issues/3

Thanks for your efforts to bundle Enpass for snap store. We are a short on team to handle all kind of packaging. We will give you explicit permission to redistribute our software for snap store. Please share your email id in PM.

As about other bugs, issue 1 can be resolved from our side by checking a Environment variable set by snap. Browser extension connection requires permissions to require system commands like readlink/netstat/lsof and a port open on localhost. Team is investigating the issues and possible fixes.

I tried to make the store page resemble the rest of the platforms and used the official Linux Presskit for artwork and screenshots. If there's anything you would like to see changed or improved, please let me know! Even the smallest details matter.

This is still an issue with the latest release, I came here after trying everything and after a little bit of scrolling i found killall snap-store and then sudo snap refresh worked a treat. I no longer have an update which is refusing to update so thank you all.

Devices with valid serial assertions for models belonging to a specific brandcan authenticate to such on-prem store and get access to imported brand storesnaps which are not accessible to any other devices connecting to that on-premstore.

To deploy an offline store (Snap Store Proxy in air-gapped mode) to a machinewithout internet access it's possible to register it using a separate machinefirst and install the resulting package on the target machine.

On-prem stores need various data (assertions, snap binaries and metadata,account information) - produced by the upstream Snap Store - to function. Thisdata has to be exported from the SaaS IoT App store and imported into theon-prem store at least once.

Anyaccount keysused for signing brand devices'models andserials have to beregistered with the SaaS Snap Store using snapcraft register-key (by the brandaccount) prior to the export in order for the on-prem store to be able toauthenticate brand store devices.

To export brand store metadata needed for import to the on-prem store, thestore-admin export store command can be used on a machine with internetaccess. Authentication using an account with Admin role for the brand store inquestion is required. Example:

Registered public keys in form of account-key assertions for key IDs specified with the --key option. Make sure to include the keys used for signing client device serial and model assertions. These keys have to be registered using snapcraft register-key command prior to the export, by the brand account.

Snaps available in the SaaS stores, with their metadata and assertions. Currently published revisions of the snaps will be exported according to the specified architectures and channels: --arch, --channel. The --no-snaps option can be used to skip the export of any snap revisions (store-admin export snaps can be used to export snaps in a more granular fashion).

It's possible to export snaps from the upstream Snap Store and import them intotheir on-prem store. These will be the only snaps (and their revisions)available for installation from the on-prem store.

Devices that connect to a store expect that snaps pre-installed on those deviceswill be available in that store. Otherwise common operations like snap refreshwill fail. Air-gapped store operators should ensure that all necessary snaps areimported. Snaps commonly pre-installed on devices may include but are notlimited to:

Snaps end in the .snap extension, which is essentially a compressed filesystem that uses the SquashFS format and contains the entire package module, including the application, its dependent libraries, and additional metadata.

Snapd (or snap daemon) uses the snap metadata to set up a secure sandbox for applications on your system. Since it's a daemon, the entire task of maintaining and managing the snap environment happens in the background.

Snaps reside in the Snap Store, and you can explore and download them just like you do with other package managers. Additionally, you also get the option to publish your own snap packages directly to the Snap Store, which is not possible with traditional package managers.

Besides these elements, Snap also has another essential component known as a channel. A channel is responsible for defining which version of a snap is installed and tracked for updates on your system. As a result, when you install or update snaps, you get the ability to specify the channel you want to proceed with for each of these operations.

Since snapd is an essential component of Snap, it's the first thing you need to install on your system. If you're running any of the following Linux distros, though, you already get snapd pre-installed on your system: KDE Neon, Manjaro, Ubuntu (16.04/4 LTS and 20.04 LTS), Zorin OS. 2351a5e196
