Help upgrading Kubuntu 18.04 to 20.04.1 - unresolvable problem occurred while calculating the upgrade.

Asked by Steven Mapes on 2021-01-27

I could really do with some help figuring out how come I can not upgrade my laptop from Kubuntu 18.04 to 20.04.1

I've had a look around but all the simliar issues I have seen online appear to have more information presented to them when the upgrade fails.

I run ```sudo do-release-upgrade ``` and receive the following output at the end

```

Calculating the changes

Could not determine the upgrade

An unresolvable problem occurred while calculating the upgrade.

If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If
you want to investigate this yourself the log files in
'/var/log/dist-upgrade' will contain details about the upgrade.
Specifically, look at 'main.log' and 'apt.log'.

Restoring original system state

Aborting
Reading package lists... Done

Reading state information... Done
```

I've moved all files from /etc/apt/sources.list.d/ to a backup folder in /home/ which is on a different partion.

I then disabled three entries from /etc/apt/sources.list for 3rd party ppa's for Wine, Docker and Stripe

These were the entries
deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main
deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable
deb https://dl.bintray.com/stripe/stripe-cli-deb stable main

Leaving these left in the file

```

deb http://security.ubuntu.com/ubuntu bionic-security multiverse
```

apt.log has a lot of entries in it

I checked for any broken packages but could not see any

```dpkg -l | grep ^..r ``` -no results

```
sudo apt-get check

```

```dpkg-query -W -f='${db:Status-Abbrev} ${binary:Package}\n' | grep -E ^.[^nci]``` also no output

```

So I'm lost as to what to do next. If the problem is Python2 which was part of Kubuntu 18.04 still, I don't know what action to take next.

Okay I've gotten further by removing Python2 completely using

```
apt-get purge python2*
apt-get purge libpython2*
```

@Steven:

What happened after you removed these python packages? Did the upgrade process complete successfully or did it still fail only later on?
