Public bug reported: After updating to Edgy, I realised I was not booting onto the right partition, which lead to an unbootable system, until I noticed that /etc/fstab had the same UUID for 2 different partitions. The solution I've adopted so far is to remove the UUIDs and go back to the good ole /dev/hd* descriptions.
Just a little background: the partitions affected by this are /dev/hda5 (where I did the upgrade to Edgy) and /dev/hda9 (where I had a copy of my previous Dapper system). Before the upgrade, both partitions where identical, since /dev/hda9 was simply a copy of /dev/hda5 I made with gparted in case the upgrade went wrong. In this way I would still have my old Dapper. Anyway, here's the /etc/fstab generated after the upgrade to Edgy (notice /dev/hda5 and /dev/hda9 have got the same UUIDs). # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/hda5 -- converted during upgrade to edgy UUID=f0bfe866-2449-4d75-8222-b444ff564876 / ext3 defaults,errors=remount-ro,user_xattr 0 1 # /dev/hda9 -- converted during upgrade to edgy UUID=f0bfe866-2449-4d75-8222-b444ff564876 /media/ubuntu/dapper ext3 defaults 0 0 # /dev/hda1 -- converted during upgrade to edgy UUID=1E4F-1A0D /media/windows/C vfat shortname=winnt,codepage=850,umask=000,user,exec 0 0 # /dev/hda7 -- converted during upgrade to edgy UUID=b7ffa27f-4c89-4b7f-82cc-e18afa7f6552 none swap sw 0 0 # /dev/hda8 -- converted during upgrade to edgy UUID=4401-99ED /media/windows/Y vfat shortname=winnt,codepage=850,umask=000,user 0 0 # /dev/hdb1 -- converted during upgrade to edgy UUID=1AF1-4021 /media/windows/D vfat shortname=winnt,codepage=850,umask=000,user 0 0 # /dev/hdc1 -- converted during upgrade to edgy UUID=908ce3ae-1ac8-450e-b6b6-9dfdb71aef2c /media/debian/etch ext3 defaults 0 0 # /dev/hdc6 -- converted during upgrade to edgy UUID=7b19bf37-516b-47c9-beea-108abf1582e3 /media/lfs ext3 defaults 0 0 /dev/hdd /media/cdrom0 udf,iso9660 user,noauto 0 0 ** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- Duplicate UUIDs after Edgy update https://launchpad.net/bugs/64909 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
