That behaviour still on today even system is up to date. SC still able to display proposed software and install them. Difference with Lucas Chiodini's case is that the "History" button contains correct history. I order to uninstall/remove any software, I have to remember its name and make a search in "All software" button, so it is able to display whether that software is installed. When installed it propose a remove button.
I don't know which any previous action could made SC to loose its functionnality for "Installed" button. Can "Ubuntu Tweak" be the cause ? (I ran it before the issue as I remember but not sure). System details: - System has 1GB RAM - Ubuntu is 12.04 kernel 3.2.0-35 generic - Software Center is 5.2.7 - Ubuntu Tweak is 0.8.3 - System is used as web server only (LAMP) - SearhMonkey 0.8.1-8 was installed for few days but I removed it because of bugs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/916054 Title: software center doesn't list programs installed by .deb To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/916054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
