I'm trying to upgrade from 20.10 to 21.04
I looked at /var/log/dist-upgrade/main.log and I can see problems around these lines, but aren't sure what to do:
2021-05-13 20:07:50,142 DEBUG Marking 'ubuntustudio-desktop' for upgrade 2021-05-13 20:07:50,287 DEBUG blacklist expr 'ubuntustudio-desktop' matches 'ubuntustudio-desktop-core' 2021-05-13 20:07:50,287 DEBUG The package 'ubuntustudio-desktop-core' is marked for removal but it's in the removal blacklist 2021-05-13 20:07:50,293 ERROR Dist-upgrade failed: 'The package 'ubuntustudio-desktop-core' is marked for removal but it is in the removal blacklist.' 2021-05-13 20:07:50,293 DEBUG abort called
Is there a work-around for this or a way to discover an underlying problem?
