Troubleshooting Snap with SELinux on Fedora Linux
Fedora’s SELinux (Security-Enhanced Linux) feature is essential for system security, but its strict policies can sometimes interfere with Snap operations. 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 recentThis 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 0If Snap functions correctly in permissive mode, SELinux is likely the cause. Revert to enforcing mode when testing is complete:
sudo setenforce 1Option 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.logThis 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 -M snap_policy < /tmp/avc.logThis 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.ppThis applies the custom policy, resolving the SELinux conflict while keeping enforcement active.
Removing Snap and Snap-Store from Fedora Linux
If you no longer wish to use Snap and Snap-Store on your Fedora system, 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 snapdThis 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 listIf 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 snapdThe service should no longer be active. If it shows as inactive or not found, the removal process is complete.
