User Installation
Add the AGL PENS Store repository to your Flatpak setup and install apps on any Linux distro that supports Flatpak.
Requirements
Flatpak must be installed on your system. Install Flatpak →
One-time setup
Add the AGL PENS Store remote
Register the repository with Flatpak using this command:
flatpak remote-add --if-not-exists pens-agl https://repo.agl-store.cyou
The --if-not-exists flag makes it safe to run multiple times. You can use any remote name you like — pens-agl is recommended.
Trust the repository GPG key
The store signs all published apps with its GPG key. Import and trust it so Flatpak can verify signatures:
flatpak remote-modify --gpg-import=<(gpg --export 308C9B02C9079D45BFE90350E9ADCFFF97CE5264) pens-agl
Or using curl directly:
curl -s https://repo.agl-store.cyou/gpg-key | flatpak remote-modify --gpg-import=- pens-agl
GPG fingerprint: 308C9B02C9079D45BFE90350E9ADCFFF97CE5264
Verify the remote was added
flatpak remotes
You should see pens-agl listed with the URL https://repo.agl-store.cyou.
Installing apps
Browse the store homepage to find app IDs, then install with:
flatpak install pens-agl <app-id>
For example:
flatpak install pens-agl org.gnome.Calculator
To install multiple apps at once, separate their IDs with spaces:
flatpak install pens-agl org.gnome.Calculator org.gnome.TextEditor
Running apps
Installed apps appear in your application launcher automatically. You can also launch from the terminal:
flatpak run <app-id>
Updating apps
Update all installed apps (including from other remotes):
flatpak update
Update only apps from this store:
flatpak update --app --installation=user --remote=pens-agl
Removing apps or the remote
Uninstall a specific app:
flatpak uninstall <app-id>
Remove the AGL PENS Store remote entirely:
flatpak remote-delete pens-agl
Troubleshooting
Remote not found after adding
Run flatpak update to refresh remote metadata after adding a new remote.
GPG verification failed
Re-run the GPG import step from Step 2 above. The key fingerprint must match 308C9B02C9079D45BFE90350E9ADCFFF97CE5264.
App not found in remote
Run flatpak remote-ls pens-agl to see all available apps.
Permission errors
Add --user to install for your user only (no root needed), or --system with sudo for system-wide installation.
