I had this problem as well/ I'm running soft raid with raid-0 on Intel chipset. Upgrade all completed, but upon reboot I got grub_env_export error.
The problem is that the upgrade did not create a dmraid initrd image. I booted from live CD and CHROOTed. Then did: apt-get purge dmraid apt-get install dmraid grub install /dev/mapper/isw_jfijhfbah_MY_RAID update grub. Rebooted and everything was fine. Needless to say that this would be way beyond a non linux expert. I had exactly the same problem when I upgraded from Lucid to Maverick. So to have exactly the same problem when upgrading to narwhal is extremely disappointing. You need to start testing RAID installs and upgrades properly Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/756564 Title: After Maverick to Natty upgrade, grub won't boot and displays "symbol not found : 'grub_env_export'" -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
