Indeed. This also seems to have an impact where buster changed from
"testing" to "stable", see https://bugs.debian.org/931543.

That's actually prompted by a change in libapt (as Sven already
pointed out in #931543) which aptitude indeed hasn't been updated a

I though must admit that we actually were aware of this issue as I ran
into it with a third-party repo a few months ago, see
https://bugs.debian.org/915246. But admittedly I totally
underestimated its severity and especially also its impact at release
time as I didn't think of that exactly the same will happen when
Debian shifts all suite names at release time. Sorry for that.

I hope that Manuel (CCc'ed) can provide a fix which we then can also
apply to aptitude in Buster in the first minor update which is
expected in about a month.

The official workaround is to use "apt update" once inbetween, answer
its questions (with "y" :-) and then continue to use aptitude.
