Now I have a bad connection every 1-3 days, and I have to update manually with the upgrade-nonroot command, how do I set up automatic updates?
This isn’t easy due to technical difficulties. Details:
(Whonix is based on Kicksecure which inherits these limitations from Debian.)
This is possible the same way this is possible to do in Debian.
