Bug Description

I was upgrading my workstation from 19.04 to 19.10 and following that to 20.04. In each case I used do-release-upgrade (without and with -d respectively). The 20.04 upgrade failed as the tool crashed on invalid function signature:

Original exception was:
Traceback (most recent call last):
  File "/tmp/ubuntu-release-upgrader-f_816ncr/focal", line 8, in <module>
    sys.exit(main())
  File "/tmp/ubuntu-release-upgrader-f_816ncr/DistUpgrade/DistUpgradeMain.py", line 238, in main
    if app.run():
  File "/tmp/ubuntu-release-upgrader-f_816ncr/DistUpgrade/DistUpgradeController.py", line 2082, in run
    return self.fullUpgrade()
  File "/tmp/ubuntu-release-upgrader-f_816ncr/DistUpgrade/DistUpgradeController.py", line 1998, in fullUpgrade
    if not self.doDistUpgradeFetching():
  File "/tmp/ubuntu-release-upgrader-f_816ncr/DistUpgrade/DistUpgradeController.py", line 1233, in doDistUpgradeFetching
    self.cache._fetch_archives(self.fetcher, pm)

Same here. Ran "pkexec do-release-upgrade -m desktop -f DistUpgradeViewKDE" and this crashed after a short time, with the above exception in /var/log/dist-upgrade

Annoyingly, the tool had already made sufficient changes (to the sources.dist?), so re-running the upgrade, even from the command line (sudo do-release-upgrade -m desktop) resulted in an error saying I had packages to upgrade. Which of course I did, thousands of them.

I ran apt full-upgrade and now I can run "sudo do-release-upgrade -m desktop". But it only says no upgrades found. So I have no idea whether any further action needs to be taken or not.

How can I resume the upgrade, or manually do whatever clean ups are necessary now that the packages are upgraded???

sudo mv /etc/apt/sources.list.distUpgrade /etc/apt/sources.list
sudo apt update
sudo apt install python3-apt=1.8.4
sudo do-release-upgrade

That gets it going for Lubuntu 19.04 to 19.10 upgrade.

That does not work because it now wants to upgrade python3-apt. (For Kubuntu)

# apt install python3-apt=1.8.4

# do-release-upgrade
Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.

# apt upgrade
The following packages will be upgraded:

Sorry forgot that I commented out the updates and security repositories in /etc/apt/sources.list . You can probably hold the python3-apt package to get the same effect.
