[Aptitude-devel] Bug#931718: new packages list forgets about old packages

[Matus UHLAR - fantomas]

Package: aptitude
Version: 0.8.7-1

I am trying to look which packages are new in buster that were not in
stretch. I am using aptitude since it't great tool for browsing packages.

until now it was easy:

do 'f'orget new packages in aptitude
change sources.list to point to new release
do 'u'pdate packages list
... voila

but now, when I do this, aptitude seems to forget all info about packages
previously available.

This was not an issue in jessie (0.6.11-1+b1) and previous versions.

when I have tried to run "apt update" after changing sources.list, and run
aptitude, the expected (former) behaviour was encountered.
(even when I furtger 'u'pdated in aptitude).

the pkgstates contained differencies between releases:

# diff -u /tmp/pkgstates.old /tmp/pkgstates.apt-update
