[Bug 1967464] [NEW] i am unable to update my ubuntu from 20.04 LTS to any new version

[om dewangan]

Public bug reported:

i am trying to update my ubuntu from 20.04 LTS to any new version , I
have tried with software updater but it not updated , then I go with
terminal and it is showing :

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'.
