Again, I hate to do this, but until we've figured this out, can the two
of you please do me a favor? Before you run each apt upgrade, please
save a backup copy of /var/lib/apt/listchanges, then if the problem
happens during the upgrade, please send me the backup copy of the file
as well as the new version of the same file that should have been
modified during the upgrade. I think this must have something to do with
what's in your seen database but I am unable to recreate a database that
triggers the issue, so I think I need to see yours.
There's nothing private in the database, it's just package names, MD5
checksums of changelog entries, and timestamps, though I suppose if you
have packages on your computer you don't want people to know you've
installed then that's private. :shrug: Your call. If you don't want to
post it in the bug you can email it to me privately and I certainly
won't post it anywhere.
Sorry for the trouble and thanks for the help.
