[Bug 2004571] [NEW] Can't upgrade from 20.04 to 22.04

[Roberto de Oliveira Santos]

Public bug reported:

I'm trying to upgrade from 20.04 to 22.04 but I'm getting this error:

"Could not calculate the upgrade

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've tried this commands:

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
dpkg --get-selections | grep hold
sudo apt auto-remove

All of them run ok or with no output but I still can't upgrade to 22.04.

Any ideas?
