Or would we be looking at a time frame longer than that?         > Date: Fri, 18 Sep 2009 13:59:33 +0100 > From: hughsient@gmail.com > To: packagekit@lists.freedesktop.org > Subject: Re: [packagekit] Packagekit and Ubuntu > > 2009/9/18 Michael Vogt <mvo@ubuntu.com>: > > In some (rare) cases the sane default is to not allow the package to > > get installed.
