Bug Description

[Current Behavior]
Users still on Kinetic and Lunar are prompted to upgrade to Noble via the motd, however d-r-u claims that upgrading from those releases -> noble is unsupported. You also can not upgrade to mantic anymore, so you would need to manually change your sources to facilitate the upgrade.

[Expected Behavior]
Despite these releases being EOL, historically we have allowed d-r-u (hirsute->jammy for example).

[Replication Steps]
Launch a lunar instance, upgrade to latest packages, and call do-release upgrade

[Root Cause]
It appears that we're missing DistUpgrade.cfg.jammy for kinetic/lunar's UpgradeTools . Ideally we should fix this to allow easier upgrades to supported releases, as we had previously.

Actually, we are missing a parallel to DistUpgrade.cfg.jammy named DistUpgrade.cfg.kinetic and DistUpgrade.cfg.lunar. As there needs to be a DistUpgrade.cfg for the release from which you are upgrading which says what release you can upgrade to (see [Sources]) among other things.

This all seems prone to breakage though.

same issue for me:

Can not upgrade

An upgrade from 'lunar' to 'noble' is not supported with this tool.
