I get caught in this loop now and then. It happens to my laptop when I have a set of Logitech USB headphones and a second display hooked up via HDMI. If I remove those, it boots normally.
This time I discovered it happened to both lightdm and gdm. Up to today, I thought it was lightdm related. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249407 Title: package lightdm 1.8.4-0ubuntu1 failed to install/upgrade: subprocess installed post-removal script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1249407/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
