Comment 2 for bug 1121325

I see the issue with aptitude here, but I think ppa-purge was not supposed to work, if the pkgs are not available for precise. Which release was there for the pkgs then? "apt-cache policy <pkgname>" shows.

BTW If there are pkg available in r.g. trusty-updates, "apt-get install <pkgname>/trusty" seems to use it.
