I ran do-release-upgrade on an Ubuntu 18.04.6 (LTS) machine.
It threw some python package related errors and I panicked and terminated the screen.
Now I'm left with this:
root@h2838745:~# apt upgrade
Reading package lists... Done

Calculating upgrade... Done
The following packages have been kept back:
gcc-8-base manpages-de php-fpm php-mbstring php-zip
0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.
Some smaller kept back ones I could install / upgrade with apt install <package>
apt upgrade <package> would not do it.
But when trying apt install gcc-8-base I get:
root@h2838745:~# apt install gcc-8-base

Seems gcc-8-base is the base for the new ubuntu version or sth. like that :)
I'd try do-release-upgrade again but the command isn't installed anymore and apt install ubuntu-release-upgrader-core says
root@h2838745:~# apt install ubuntu-release-upgrader-core
Reading package lists... Done

Package ubuntu-release-upgrader-core is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'ubuntu-release-upgrader-core' has no installation candidate

Has some kind soul any pointer for a stranded keyboard cowboy? :)
