I've upgraded a server via `do-release-upgrade` from Ubuntu Bionic to Focal, with molly-guard installed on it - molly-guard configured to always ask for the hostname.
After it has finished:
```
System upgrade is complete.
Restart required
To finish the upgrade, a restart is required.
If you select 'y' the system will be restarted.
Continue [yN] y
I: molly-guard: reboot is always molly-guarded on this system.
Please type in hostname of the machine to reboot:
Good thing I asked; I won't reboot bates ...
It doesn't alert you it was restoring original state of sources.list.
After rebooting the system and it came back up showing `Welcome to Ubuntu 20.04 LTS`, I've just noticed it was pointing out to bionic instead of focal installing a package.
