Upgraded a Strato VPS:
The same as @yonkoc
Second: I got the installer to:
Initializing system random number generator...
Creating SSH key for backup…
Firewall is active and enabled on system startup
When I got the error:
Failed to restart systemd-resolved.service: Unit systemd-resolved.service is masked.
I had to run
systemctl unmask systemd-resolved.service
Now I have one rather important issue left:
Incoming Mail (SMTP/postfix) is not running (port 25).
Anyone know what to do about this? I have rebooted and rerun the install script a couple of times but it does not solve the problem. I have run
ufw status but the port shows as allowed anywhere.
The first 2 issues are solved. The third issue is stil present.
