Ah, as I suspected. Your fstab has UUID=4bf3a782-af3c-46c4-b9ab-7988da79e800 / ext4 errors =remount-ro 0 1
which does not exist. According to blkid, you most likely want this partition: /dev/sda5: UUID="6f78ae63-3c82-451c-822f-4014f48ea22a" TYPE="ext4" PARTUUID="7448d815-05" So please fix your /etc/fstab to use this UUID for the root partition, then everything will be in order again. Do you have any idea what broke this? ** Changed in: systemd (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1449101 Title: Upgrading Kubuntu 14.10 to 15.04 boots to console (fails due to read- ony file system) Status in systemd package in Ubuntu: Invalid Bug description: After upgrading from Kubuntu 14.10 to 15.04 (final) booting fails.
