[Bug 2017799] [NEW] Unable to upgrade to 22.4 .

[k krishna Rishi]

Public bug reported:

getting the error:Could not calculate the upgrade   An unresolvable
problem occurred while calculating the upgrade.   This was caused by:  *
Upgrading to a pre-release version of Ubuntu  This is most likely a
transient problem,  please try again later.  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 to solve in multiple ways. I tried to update the sources.list
file. I dont know where the error is arising from.
