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 Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed. You need first add the *snappy* repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor. Tumbleweed: ``` sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy ``` Leap 15.x: ``` sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy ``` If needed, Swap out `openSUSE_Leap_15.` for, `openSUSE_Leap_16.0` if you’re using a different version of openSUSE. With the repository added, import its GPG key: ``` sudo zypper --gpg-auto-import-keys refresh ``` Finally, upgrade the package cache to include the new *snappy* repository: ``` sudo zypper dup --from snappy ``` Snap can now be installed with the following: ``` sudo zypper install snapd ``` You then need to either reboot, logout/login or `source /etc/profile` to have /snap/bin added to PATH. Additionally, enable and start both the *snapd* and the *snapd.apparmor* services with the following commands: ``` sudo systemctl enable --now snapd sudo systemctl enable --now snapd.apparmor ``` ### Install Day Night Theme Switcher To install Day Night Theme Switcher, simply use the following command: ``` sudo snap install day-night-theme-switcher ``` ### 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?
