Hi all,

I'm trying to unmerge some packages. They all fail like this:

As the error suggests, remove that file
(/var/db/pkg/www-client/arora-0.11.0/environment.bz2) and then try
again, it should hopefully work then.

See this bug for more info:

Nope, removing environment.bz2 doesn't make any difference. Also, note
that it's not just this package. I have the same problem for at least
2 others. It seems a pandemic. :-)

Have you tried upgrading to the latest version of Portage 2.2? The
newest version in the tree is currently portage-2.2_rc95, while you're
still using portage-2.2_rc67. Perhaps there's a bug causing this that
was fixed in subsequent release?

Hm, well I'm just now updating my ~amd64 machine and I see that both python
and portage are about to be updated. I'm still with the 2.1.x portage, so
I can't comment on the version you're running. Were your python and portage
just recently updated?

Did you run python-updater after the upgrade? Perhaps the python ebuild does
that for you, I'm not sure. Anyway I'd run it again just to make sure.

This could be a new bug in portage, too. I'd suggest downgrading to your
previous portage version -- but I'm not sure how safe that is. Anyone else
know?
