They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd On Arch Linux, snap can be installed from the [Arch User Repository (AUR).](https://aur.archlinux.org/packages/snapd/) The [manual build process](https://wiki.archlinux.org/index.php/Arch_User_Repository#Installing_packages) is the Arch-supported install method for AUR packages, and you’ll need the [prerequisites](https://wiki.archlinux.org/index.php/Arch_User_Repository#Prerequisites) installed before you can install any AUR package. You can then install snap with the following: ``` git clone https://aur.archlinux.org/snapd.git cd snapd makepkg -si ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` If [AppArmor](https://wiki.archlinux.org/title/AppArmor) is enabled in your system, enable the service which loads AppArmor profiles for snaps: ``` sudo systemctl enable --now snapd.apparmor.service ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly. ### Install Screen Pixel Ruler and Loupe To install Screen Pixel Ruler and Loupe, simply use the following command: ``` sudo snap install pixel-ruler-protractor ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
