Public bug reported:
I was offered the upgrade to 18.04 LTS. I selected, "Upgrade". It
started ticking off bullets on the list, and then said,
|
| Could not calculate the upgrade
|
| An unresolvable problem occurred while calculating the upgrade.
|
| This can be caused by:
| * Upgrading to a pre-release version of Ubuntu
| * Running the current pre-release version of Ubuntu
| * Unofficial software packages not provided by Ubuntu
|
| If none of this applies, then please report this bug using the command
'ubuntu-bug ubuntu-release-| upgrader-core' in a terminal.
|
As you can see, it doesn't really tell me what I need to fix to get the
upgrade to calculate correctly (ie. the actual thing it found that it
didn't like).
I don't want to fall behind, but this bug seems to block me from
upgrading. It needs to provide remedy details to allow the operator to
make targeted corrections and then run again. Too little info provided
to be useful.
