That's what I mean by own.  As long as those diversions weren't removed,
nvidia-glx should never have been installable, and if those diversions
were removed, that should have been followed by removing the postrm
script... oh.  Oh, I get it.  You removed the package but didn't purge it,
and the postrm script removes the diversions on both remove and purge.
Aie.  Yeah.

I see how you got into that situation.  I don't think there's any good
solution at this point other than commenting out the dpkg-divert
invocations in the postrm script and then purging the package.
Thankfully, once someone upgrades to one of the new packages, this problem
should be impossible to create.

Already in the archive for nvidia-glx, in NEW for the legacy package.

Not yet, but it makes it possible eventually.

Yeah, that's still a problem.

Oh, I see.  But yes, the more I think about it, the more I think you're
right: trying to upgrade the package won't help.
