I am not surprised. Arm runs as user “user”. Tor as “debian-tor”. I don’t think this would work on Debian either, see also:
Tor is best started by the Debian mechanisms:
sudo service tor stop
sudo service tor start
Or use whonixsetup to enable/disable Tor networking.
Yeah, I tried to start and stop Tor with “sudo service tor …” and it works normally.
Thanks for help
