Public bug reported:

When trying to upgrade from lunar to mantic, I originally got the
following error message:

> An unresolvable problem occurred while calculating the upgrade.
> 
>  This was likely caused by:
>  * Unofficial software packages not provided by Ubuntu
> Please use the tool 'ppa-purge' from the ppa-purge 
> package to remove software from a Launchpad PPA and 
> try the upgrade again.
> 
> 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'.

I tried the following steps to fix the issue:

- made sure my apt sources didn't contain PPA packages or external
sources:

    egrep -v '^#|^ *$' /etc/apt/sources.list /etc/apt/sources.list.d/*
    /etc/apt/sources.list:deb http://mirror.eu-fr.kamatera.com/ubuntu/ lunar main restricted
    /etc/apt/sources.list:deb http://mirror.eu-fr.kamatera.com/ubuntu/ lunar-updates main restricted
    /etc/apt/sources.list:deb http://mirror.eu-fr.kamatera.com/ubuntu/ lunar universe
    /etc/apt/sources.list:deb http://mirror.eu-fr.kamatera.com/ubuntu/ lunar-updates universe
    /etc/apt/sources.list:deb http://mirror.eu-fr.kamatera.com/ubuntu/ lunar multiverse
    /etc/apt/sources.list:deb http://mirror.eu-fr.kamatera.com/ubuntu/ lunar-updates multiverse
    /etc/apt/sources.list:deb http://mirror.eu-fr.kamatera.com/ubuntu/ lunar-backports main restricted universe multiverse

    /etc/apt/sources.list:deb http://mirror.eu-fr.kamatera.com/ubuntu/ lunar-security multiverse

- made sure I didn't have any foreign repositories installed:

    grep Foreign /var/log/dist-upgrade/main.log
    2023-11-25 19:10:41,959 DEBUG Foreign: 

- I remembered that `sudo apt upgrade` had shown some "held back"
  packages, so I installed all of them with
  `sudo apt-get --with-new-pkgs upgrade <list of held-back packages>`.
  Afterwards, `sudo apt upgrade` no longer showed any held-back packages.

When I now try to update to mantic, I get a slightly shorter error
message:

> Could not calculate the upgrade
>
> An unresolvable problem occurred while calculating the upgrade.
>

(including the space at the beginning of the last paragraph (before "If
none of this ..."), which indicates to me that may there be should have
been a list of possible reasons here but it just happens to be empty in
my case)
