molly-guard causes do-release-upgrade to fail

[Leroy Tennison]

On an Ubuntu 16.04 LTS to Ubuntu 18.04 LTS upgrade, even if you use apt-get purge molly-guard before the upgrade and reboot without being prompted for the system name, molly-guard somehow magically comes back and, at the end of the upgrade, the following occurs:

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
W: molly-guard: SSH session detected!
Please type in hostname of the machine to reboot:
Good thing I asked; I won't reboot cedar-falls-ivr-pri2 ...

At this point you terminate the screen session and reboot. If you back out of the upgrade the system is left in an inconsistent state: The software is for Ubuntu 18.04 but /etc/apt/sources.list is for Ubuntu 16.04

This has happened on several Ubuntu 16.04 LTS to Ubuntu 18.04 LTS upgrades.

I'm sorry, I might be missing something here, but I don't really understand what this issue has to do with easy-rsa?

[Leroy Tennison (ltennison)]

Thanks for contacting me.  I actually have two bugs filed: 1932045 and this one.  I don't know what happened or how 1932045 (easy-rsa) got listed as "Affects" for this bug but the two have nothing to do with each other.  If i knew how to remove easy-rsa as "Affects" for this bug I would but I don't see any way to do so.  If you can dis-associate the two i would appreciate it.  Thanks for your help.
