Hi, this still happens on 14.04 64bit. A test case can be the crossover .deb package.
https://media.codeweavers.com/pub/crossover/cxlinux/demo/crossover_14.0.3-1.deb The USC opens and offers to install the package. After installation it does not show it as actually being installed even if it is. The same thing happens with gdebi. apt-cache policy crossover returns: silviu@trusty:~$ apt-cache policy crossover crossover:i386: Installed: 14.0.3-1 Candidate: 14.0.3-1 Version table: *** 14.0.3-1 0 100 /var/lib/dpkg/status -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/635029 Title: Downloaded .deb doesn't appear in "Installed" after installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/635029/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
