Yep, and the later seems to have bitten me a bit when testing the
bundle. At least chromium had no more forbidden version afterwards
which was unexpected.

Then again, /var/lib/aptitude//pkgstates is in your bundle as
.//var/lib/aptitude/pkgstates, so there's no reason for a fall-back or
so.

Ack.

I know. That's the reason why I mentioned this.

Not necessarily. It's possible. But IMHO unlikely.

Since Julian has uploaded a fix as apt/2.1.18, would you mind checking
if you can still reproduce the issue in any way?
