I tried to create a client for a raspberrypi 4.

The olm Image for arm64 doesn't start

`-bash: ./olm: Kann die Binärdatei nicht ausführen: Fehler im Format der Programmdatei

-bash: ./olm: can't execute binary file: error in format of the executable file`

Then I tried the docker image for olm.

But it failed to create the /dev/net/tun device
