AppImage, Flatpak, Snap


AppImage provide everything that is needed to get executed. It works like a .exe on Windows and does not need to be installed. See here for our latest Nitrokey-App.AppImage file. After downloading the file, you need to make the file executable. You can do this by right-clicking on the file and choosing "Properties". Look for the option to make the file executable there.


Execute the following commands:
flatpak install flathub com.nitrokey.nitrokey-app
flatpak run com.nitrokey.nitrokey-app

For more information visit Flathub.


Note: There is a problem with the current Snap package. Please make sure that scdaemon is installed by typing apt-get update && apt-get install scdaemon in a terminal and follow the instruction below.

The latest Nitrokey App is available as Snap package which is available for many Linux distributions and which ensures that you always have the latest version installed.

Snapd is already installed on Ubuntu, for distros like Arch, Debian, Fedora, or Gentoo you need to install snapd first. As soon as you have Snap installed you can open a terminal and type

sudo snap install nitrokey-app --devmode
to install Nitrokey App. You now can use it as usual, e.g. by pressing Alt + F2 and entering "nitrokey-app".


In case you get the error "failed to create user data directory. errmsg: Permission denied" during starting the Nitrokey App, it may is because your home directory is encrypted. In this case, apply one of these fixes [1] [2].
