Comment 15 for bug 139138

in comment https://bugs.edge.launchpad.net/ubuntu/+source/apturl/+bug/139138/comments/14 the outlines that:

"Then, when firefox asked to install it, the installer bombed out because of a bug (I think because when I installed, I didn't have an internet connection, so there were no repositories configured that had flashplugin-nonfree (many were commented out)). However, firefox misread the installer return value and said the installation was successful when it actually failed."

this appears to be an apturl bug. if its not the wrong return value its probably a not honoured section (multiverse) hint.
