Thank you for reporting this bug to Ubuntu. Karmic reached EOL on April 30, 2011. Please see this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases
I've tried recreating this bug with Karmic and was unable to, given the information you've provided. Please either a) upgrade and test or b) increase the verbosity of the steps to recreate it so we can try again. Please feel free to report any other bugs you may find. But it looked like you reinstalled the grub headers to /dev/sda7, which caused you partition to become corrupt. ** Changed in: cryptsetup (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/495270 Title: LUKS partition corrupted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/495270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
