Snap

Besides (prefered) flatpak, MocaccinoOS also offers snap.

Installing and configuring

To install snap, run as root:

1

luet install apps/snapd

Once the snap package is installed, enable these services:

1

systemctl enable --now snapd.socket

AppArmor

Snap’s fallback behavior without AppArmor is flaky, and some snaps won’t work at all. So we must enable AppArmor on our system. It is bundled with the apps/snapd package so we already have it on the system.

Enable the apparmor service:

1

systemctl enable --now apparmor.service snapd.apparmor.service

Enable required boot parameters. Edit /etc/default/grub and append apparmor=1 security=apparmor parameters.

1

GRUB_CMDLINE_LINUX_DEFAULT="apparmor=1 security=apparmor"

After editing this file, regenerate the grub config file:

1

grub-mkconfig -o /boot/grub/crug.cfg

Now restart the system.

Using snap

To install Spotify, for example, now you can:

1

sudo snap install spotify

For a detailed documentation, we suggest as a follow-up reading the official docs, here you can find a short summary of the most used commands.

Search

Applications can be found in any of the added remotes using the search command. For example:

1

snap find spotify

Running applications

After an application is installed, can be run by their id:

1

snap run spotify

Updating

To update all your installed applications and runtimes to the latest available version in Flatpak, run:

1

snap refresh
