The stock installation of aptitude will try to install recommended packages as hard dependencies. In the case of installing selinux this results in ubuntu-standard being uninstalled (due to ubuntu-standard recommending apparmor-utils). I suspect that this is what has happened.
You can change this behavior in aptitude by turning off auto- installation of recommends in your preferences or by passing --without- recommends. This is an unfortunate case where aptitude and apt-get's behaviors diverge. -- selinux installed- can't boot-unable to mount /selinux https://bugs.launchpad.net/bugs/203645 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
