From 314b47542c57d0a12c55dd1dd334cf233a33fcfb Mon Sep 17 00:00:00 2001 From: Helmut Grohne Date: Mon, 9 Mar 2015 18:11:10 +0100 Subject: parse arch-qualified Provides correctly The underlying problem is that libapt-pkg does not correctly parse these provides. Internally, it creates a version named "baz:i386" with architecture amd64. Of course, such a package name is invalid and thus this version is completely inaccessible. Thus, this bug should not cause apt to accept a broken situation as valid. Nevertheless, it prevents using architecture qualified depends.
