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

1

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.

2

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

3

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.
