I'm trying to upgrade from Ubuntu 16.04.5 LTS to 18.04.
I ran sudo do-release-upgrade and after around 1 hour the process finished with:
Processing triggers for resolvconf (1.79ubuntu10) ...
Errors were encountered while processing:
kubuntu-desktop
Exception during pm.DoInstall(): E:Sub-process /usr/bin/dpkg returned an error code (1)
Could not install the upgrades
The upgrade has aborted. Your system could be in an unusable state. A
recovery will run now (dpkg --configure -a).
dpkg: dependency problems prevent configuration of kubuntu-desktop:
kubuntu-desktop depends on software-properties-kde; however:
Package software-properties-kde is not installed.
dpkg: error processing package kubuntu-desktop (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
kubuntu-desktop
Upgrade complete
The upgrade has completed but there were errors during the upgrade
process.
To continue please press [ENTER]
I rebooted and my linux seems to be 18.04, so I thought it was just the kubuntu-desktop install that didn't work. I tried to force install it:
sudo apt-get install -f kubuntu-desktop

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
kubuntu-desktop : Depends: software-properties-kde but it is not going to be installed
Recommends: apport-kde but it is not going to be installed
Recommends: kubuntu-driver-manager but it is not going to be installed
Recommends: kubuntu-notification-helper but it is not going to be installed
Recommends: muon but it is not going to be installed
Recommends: plasma-discover but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
In the following I always tried force installing the dependencies that were unmet:
kubuntu-desktop -> software-properties-kde -> python3-pyqt5 -> libpython3.6 -> libpython3.6-stdlib
When I tried to install libpython3.6-stdlib I get:
Reading package lists... Done
Building dependency tree
Reading state information... Done
libpython3.6-stdlib is already the newest version (3.6.7-1+xenial1).
