Thank you for taking the time to report this bug to improve Ubuntu. However, to further investigate this bug, we would need the contents of the /var/log/dist-upgrade folder, so please compress it and attach to this bug report.

This sounds similar to what I'm getting. Upgrade is failing since it can't find ubuntu-minimal from the sources list.

Attached is my dist-upgrade log folder
