Upgrading an Ubuntu to Raring Ringtail did not work properly and, now, the machine displays the screen "Ubuntu 13.04" and a few seconds after a text console with:
General errors mouting filesystems. A maintenance shell will now be started. CONTROL-D will terminate the shell and reboot the system.
fsck and mount -a show that the two partitions sda1 and sda6 are OK and can be mounted. (Ubuntu is alone on the disk, no Windows)
I made a BootRepair https://help.ubuntu.com/community/Boot-Repair CD, started on it, choosed "32bits session" then "Recommended repair", after a few minutes, the program tells me "Boot successfully repaired" and creates the report in http://paste2.org/E10Cj3VP
But, at the next boot, the problem is exactly the same ("General errors mouting filesystems."). What can I try now?
I noticed these two questions where the error message is the same but the rest of the story seems quite different : Ubuntu: "General error mounting filesystems" during boot and Ubuntu: "General error mounting filesystems" during boot
