Restic commands do not work on ARM

my system: Manjaro ARM kde plasma rpi4 v22.08


I followed the instructions here:

But I get an error:

[girl2@manjaro ~]$ sudo -u restic /home/restic/bin/restic --exclude={/dev,/media,/mnt,/proc,/run,/sys,/tmp,/var/tmp} -r /tmp backup /
Fatal: unable to open config file: stat /tmp/config: no such file or directory
Is there a repository at the following location?
[girl2@manjaro ~]$

Did you restic -r /tmp init first?

Though the location is not quite trustworthy for a backup…
