Managing Snap and the Snap Store

Now that you have successfully completed the steps to install Snap on Fedora and set up the Snap-Store, let’s explore how to efficiently manage applications and address common scenarios using these tools.

Updating All Snap Applications

Keeping your installed applications up to date ensures you benefit from the latest features and security fixes. To update all your Snap packages, run:

sudo snap refresh

This command checks for updates and applies them automatically, keeping your system secure and up to date.

Listing Installed Snap Applications

To view all applications installed via Snap, use:

snap list

This command displays a list of installed packages, including their version, publisher, and installation status.

Reverting to a Previous Version

If an update introduces issues or incompatibilities, Snap allows you to roll back to a previous version of the application:

sudo snap revert <package-name>

Replace <package-name> with the name of the application to revert it to its last working version.

Removing Snap Applications

If you no longer need an application, you can remove it easily using:

sudo snap remove <package-name>

This removes the application and any related Snap data, keeping your system clean.

Troubleshooting SELinux Issues with Snap

Fedora’s SELinux (Security-Enhanced Linux) feature is essential for system security, but its strict policies can sometimes interfere with Snap operations, especially when you install Snap on Fedora for the first time. Below are steps to identify and resolve common SELinux-related issues when using Snap.

Analyzing SELinux Denials

When Snap encounters permission issues, SELinux might be the cause. To check for denial messages, use the following command:

sudo ausearch -m AVC --start recent

This command retrieves Access Vector Cache (AVC) messages that provide insights into SELinux denials affecting Snap.

Adjusting SELinux Policies

Option 1: Temporarily Switch SELinux to Permissive Mode

To quickly test if SELinux is causing the issue, you can set it to permissive mode. This disables enforcement while continuing to log violations:

sudo setenforce 0

If Snap functions correctly in permissive mode, SELinux is likely the cause. Revert to enforcing mode when testing is complete:

sudo setenforce 1

Option 2: Create a Custom SELinux Policy

For a more permanent solution, you can create a custom SELinux policy to allow Snap operations.

Generate Denial Logs

Start by generating denial logs with the following command:

sudo ausearch -m AVC --start recent > /tmp/avc.log

This captures SELinux denial information required for policy creation.

Create a Policy Module

Use the captured logs to create a policy module. Run the following command:

sudo audit2allow -i /tmp/avc.log -M snap_policy

This generates a custom policy file based on the SELinux denials.

Install the Policy Module

Finally, install the generated policy module with the following command:

sudo semodule -i snap_policy.pp

This applies the custom policy, resolving the SELinux conflict while keeping enforcement active.

Uninstalling Snap and Snap Store

If you no longer wish to use Snap and Snap-Store on your Fedora system after you install Snap on Fedora, you can remove them entirely using the following steps. This process ensures all related files and services are cleaned up, leaving your system tidy.

Step 1: Uninstall Snap and Snap-Store

Remove Snapd and all installed Snap packages with the command:

sudo dnf remove snapd

This will uninstall Snapd, along with any Snap-installed applications and their dependencies.

Step 2: Verify the Removal

To confirm that Snap has been fully removed from your system, check for installed Snap packages using:

snap list

If Snap has been successfully uninstalled, this command should return an error or an empty result.

You can also verify the Snapd service status:

systemctl status snapd

The service should no longer be active. If it shows as inactive or not found, the removal process is complete.

Common Snap Installation Troubleshooting

While Snap is designed to be robust, you might occasionally encounter issues when you install Snap on Fedora. Here are some common problems and how to address them on your Fedora system:

Issue: `snap` command not found

If you see an error like “bash: snap: command not found,” it could be due to a few reasons:

• Snapd not installed: Ensure you have completed the installation steps for snapd. You can try reinstalling it if unsure: sudo dnf install snapd.
• System not rebooted: After the initial snapd installation, a reboot is recommended to ensure all system paths and services are correctly initialized. If you skipped this, please sudo reboot.
• PATH environment variable: The directory /snap/bin should be in your system’s PATH. A reboot usually fixes this. You can check with echo $PATH.

Issue: Snap application fails to launch or behaves unexpectedly

If a Snap application doesn’t start or crashes, try these steps:

• Run from terminal: Launch the application directly from your terminal using snap run package-name (e.g., snap run discord). This will often display error messages that can help diagnose the problem.
• Check Snap logs: Review logs for snapd using journalctl -u snapd for system-level issues.
• Refresh the snap: Sometimes, simply refreshing the snap can resolve issues: sudo snap refresh package-name.
• Revert the snap: If the issue started after an update, revert to the previous version: sudo snap revert package-name.
• SELinux: As covered in its dedicated section, SELinux can often be a source of issues on Fedora. Refer to the “Troubleshooting Snap with SELinux on Fedora Linux” section if you suspect SELinux denials.

Issue: Snap Store is slow or doesn’t show applications

The Snap Store might occasionally be slow to load, especially on its first launch, as it syncs application data.

• Wait a bit: Give it a few minutes to fully synchronize.
• Refresh Snap Store: Try closing and reopening it. You can also try refreshing it via the command line if it was installed as a snap itself: sudo snap refresh snap-store.
• Check internet connection: Ensure your system has a stable internet connection.
• Reboot: If the Snap Store icon doesn’t appear in your application menu after installation, a system reboot is often required.

Issue: Problems with classic confinement snaps

Snaps requiring classic confinement (e.g., some IDEs or development tools) need broader system access. Ensure you’ve enabled classic Snap support by creating the symbolic link: sudo ln -s /var/lib/snapd/snap /snap. If this link is missing or incorrect, classic snaps may not function properly. A reboot after creating the link can also help.
