I use a lot of repositories, I think it might be related to that.

Does this happen with 'apt update', too?
(They share most of the code, so I would "hope" yes)

It would be useful if you could share them. If not publicly at least as
a private reply as reproducing this seems hard otherwise.

Based on the aptitude version from current testing, I find it suspect to
have stable-security and co in your sources through. Nothing good comes
from there for a testing system and it might very well confuse tools
trying to reason about "obsolete" packages (disclaimer: which I think
e.g. aptitude does, but I don't use it myself).


Nothing changed in aptitude for months, and the apt side shouldn't have
that many changes related to that area, so that might very well be
a temporary thing given you experienced it now vs. last week that will
be hard to reproduce/figure out if time moves on.


Best regards

apt update seems to work fine except for some warnings at the end:
stable InRelease

I've attached an archive of my sources.d directory (my sources.list is
empty)

I've had stable, testing and unstable repositories enabled (with
apt_preferences to preferentially use packages from testing) for years
now, I haven't experienced any weirdness with "obsolete" packages.
