[Bug 2078267] Re: unresolvable error in upgrade to 24.04

[Matthew Warnock]

This seems like it could be an old bug, very smiler to [bug
996916](https://bugs.launchpad.net/ubuntu/+source/update-
manager/+bug/996916)

Do i need to remove my currant postgis and install a newer version of
postgis?


something like what Billoir Romain (maz83) wrote on 2020-04-26:
sudo apt remove postgresql-12-postgis-*

sudo do-release-upgrade

sudo apt install postgresql-12-postgis-[newer_version_number]

Title:
  unresolvable error in upgrade to 24.04

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

   The package 'postgresql-12' is marked for removal but it is in the
  removal deny list.

  To prevent data loss, postgresql packages are not removed
  automatically during the upgrade. If you are certain you no longer
  need postgresql-12, you can manually remove it 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'.

  And yet...
