Installing Nextcloud Files on Linux (AppImage)

For Linux, Nextcloud provides the desktop app as an AppImage: a single file you can run without installation, on almost any 64-bit Linux system.

Downloading and starting

Go to www.weboke.nl/download and click Linux (AppImage) (3) next to Nextcloud Files, or use this direct link: Nextcloud Files for Linux.
Make the file executable. In most file managers, right-click the file, choose Properties and tick the option to run it as a program under Permissions. In the terminal, type: chmod +x Nextcloud-*-x86_64.AppImage
Double-click the file, or start it in the terminal with ./Nextcloud-35.0.0-x86_64.AppImage (the number varies by version).
Connect your WebOké Nextcloud as described in Installing Nextcloud Files on Windows: enter the address, log in with your login code in the browser, click Grant access and choose what you want to synchronise.

The app stores its login details in your computer's keyring (for example GNOME Keyring or KWallet). Without such password management, you'll need to log in again each time.
Virtual files are still in testing on Linux (in the app: Virtual files (beta)). On Linux, it's best to choose Synchronize everything or Choose what to sync.
If you want the app to appear in your menu and start automatically, use a tool that integrates AppImages, such as AppImageLauncher. Nextcloud mentions this in its own documentation. This also makes the Open locally button in the browser work.
Many Linux distributions (such as Ubuntu, Debian, Fedora and openSUSE) also have a nextcloud-desktop package in their own software repository. This isn't made by Nextcloud itself and can sometimes be older.
For buttons in your file manager (sharing, status), install the package that matches your file manager, for example nautilus-nextcloud, dolphin-nextcloud, nemo-nextcloud or caja-nextcloud.

Tip: downloading a new version? Replace the old AppImage file with the new one. Your settings will be kept.
