Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
** Information type changed from Private Security to Public ** Summary changed: - Trusty will not install downloaded drivers with bad MD5 sums. + Trusty will not install downloaded drivers with control files with incorrect owners -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to software-center in Ubuntu. https://bugs.launchpad.net/bugs/1304666 Title: Trusty will not install downloaded drivers with control files with incorrect owners Status in “software-center” package in Ubuntu: New Bug description: Trusty will not install downloaded drivers with bad MD5 sums even when told to do so. The Google Chrome package similarly will not install. This bug is the opposite of a security vulnerability; it is security overkill that turns the system into a boat anchor. Earlier verions of Trusty and all earlier Ubuntu releases would honor a user's request to the software center request to "ignore and install". Clicking this button produces the message "The installation or removal of a software package failed." This bug applies to the 14.04 daily build for 4/08 and a few earlier builds also.
