[16:14] <marky_> Hi Ubuntu Studio folks. I wonder if someone might be able to offer me some advice: I'm trying to upgrade from 22.04 to 22.10 (and then on to 23.04). but, when i run `do-release-upgrade -m desktop` i get `Could not determine the upgrade An unresolvable problem occurred while calculating the upgrade.`  whilst /var/log/dist-upgrade/main.log reports ERROR Dist-upgrade failed: 'The package 
[16:14] <marky_> 'ubuntustudio-desktop-core' is marked for removal but it is in the removal deny list.'
[16:15] <marky_> i've tried various angles at exploring package installation and searching for error terms and I can't find anything that seems to relate to my system, nor clues about how to investigate this further
[16:15] <marky_> all thoughts and insight most gratefully received
[16:20] <tomreyn> marky_: what does    apt list ubuntustudio-desktop-core   print?
[16:20] <tomreyn> (just the one relevant line please)
[16:20] <marky_> ubuntustudio-desktop-core/now 0.210 amd64 [installed,local]
[16:20] <marky_> +=thank you
[16:32] <Eickmeyer[m]> Means it wasn't installed from the repositories bit downloaded and installed locally
[16:41] <Eickmeyer> marky_: ubuntustudio-desktop-core doesn't exist in 22.04, so remove it. This is a sign that you in-place upgraded from 20.04, despite THE RELEASE NOTES TELLING YOU OTHERWISE. NO SUPPORT IS PROVIDED.
[16:42] <Eickmeyer> Read the topic please.
[16:43] <Eickmeyer> In-place upgrades are NOT supported from 20.04 to later releases for this very reason. We can't support breakages that happen.
[16:55] <marky_> eeek; thanks Eickmeyer, i can see that that may well have happened, and i may not have properly read release-notes in the past
[16:56] <marky_> I'll have an explore and see what i can do with regard to removing ubuntustudio-desktop-core and evaluating upgrades
[16:56] <Eickmeyer> marky_: Just as a warning, 22.10 goes EOL on Thursday, so your time is a bit limited.
[16:57] <marky_> indeed, i had realised this, hence revisiting this today (having failed and puzzled and given up once)
[16:57] <marky_> I only want to upgrade off LTS if i can double upgrade via 22.10 to 23.04
[16:58] <Eickmeyer> You may have to back-up your home directory and reinstall if it takes too much time to do the upgrade (as was advised for 20.04 => 22.04).
[16:59] <marky_> i keep /home et al on separate partitions, with backups, so a fresh install of 23.04 isn't a bad option for me (just setup & config faff and so on); i'll keep it in mind
[17:01] <marky_> many thanks for the advice
[17:01] <Eickmeyer> Quite welcome.
