I'm also seeing this on Ubuntu when upgrading from 1:7.0-122+1ubuntu1 to
1:7.0-164+1ubuntu1. I don't think the Ubuntu changes are relevant.

It's got something to do with existing alternatives. I've attached my
/var/lib/dpkg/alternatives/view, which mentions ru.KOI8-R and ru.UTF-8.

Strangely, though, repeated 'dpkg --configure -a' invocations sort it
out, which suggests that one way to work around this would be to retry
each update-alternatives call once if it fails. Nasty, but perhaps
functional.

update-alternative does have code to discard obsolete slave links (look
for "obsolete" in /usr/sbin/update-alternatives). Perhaps there's some
way to get it to do that more competently?

In any case, this does feel like an update-alternatives bug as well,
even if you work around it in vim.

Cheers,
