I have been updating net-misc/networkmanager in one emerge instance and another has been doing "emerge -uN1f" of many packages. Usually the lockfile keeps care of eventual conflicts between multiple instances of emerge utility, however, this condition seems to have escaped so far. Below you can see that after some unrelated files checksum computation emerge wanted to look for net-misc/networkmanager-1.2.4 but that failed. At the moment I already had been upgraded to 1.4.0. Maybe this is too rare to care. ... >>> Fetching (1 of 1) sci-biology/blue-1.1.3::science * blue-1.1.3.tar.gz SHA256 SHA512 WHIRLPOOL size ;-) ...

This is interesting because it occurs during the FakeVartree.sync method, while it holds a lock on /var/db/pkg. Even if FEATURES=parallel-install enabled, this lock is supposed to prevent /var/db/pkg from being modified by a concurrent process.
Here is is the missing portion of emerge --info, just in case you wanted to check the FEATURES variable. I felt brave enough to omit the "unrelated" portion. Sorry for that.

Assuming that the lock works as intended, we might suspect that the KeyError could be explained by a stale result returned from the vardbapi.cpv_all method here: https://gitweb.gentoo.org/proj/portage.git/tree/pym/_emerge/FakeVartree.py?h=portage-2.3.0#n231 However, this code relies of the portage.util.listdir module, for which caching has been disabled: https://gitweb.gentoo.org/proj/portage.git/commit/?id=0196031ce8f5dc8b9385e06013e42c47d1185a3b

Since it was triggered by smart-live-rebuild, it's a separate issue. In that case emerge would have to lock the package database during evaluation of package sets.

I don't understand why the above output appears just before the dependency calculation traceback. Normally emerge doesn't calculate dependencies just after fetching something like that.

In that case, the current user does not have privileges to lock /var/db/pkg, so there's no way to prevent the KeyError from happening. There's not really a good way to handle such an error other than to abort, since /var/db/pkg could be continuously mutating.
