I'm having the same problem suddenly after a recent update and cannot boot up at all:
Mountall: Plymouth command failed Mountall: Disconnected from Plymouth Mountall: Event failed After this, there are a few gibberish characters and the system refuses to boot. If I let it sit a while, some lines about timeouts and Xrog being blocked appear but still no boot although occasionally something I press on the keyboard (I'm not sure what) will make it continue with the boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/855933 Title: mountall: Plymouth command failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/855933/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
