OK, so I think this is confirmed as somehow PackageKit-related.

I had a look through the code for "apt update" and the PackageKit APT
back-end to see what might be different.  I think this has something to
do with the different pkgAcquireStatus subclasses they use, but I
couldn't identify a specific bug in PackageKit.

I experimented with writing a test program that implements its own
pkgAcquireStatus, and I I'm attaching the source for that.  It needs to
be run on a system where a local InRelease file is out of date.  If you
answer "no" to the Pulse() after the *second* time the InRelease file is
reported done, that should reproduce the broken state.

(The default answers are set for my VM snapshot which now has very
outdated InRelease files, so I know that the Pulse() after a
ReleaseInfoChanges() is the place to stop.)

Ben.

If at first you don't succeed, you're doing about average.
