I can confirm the fix in comment #4 worked for me as well. I had a 12.04.5 system running with Full Disk Encryption (from initial install). After upgrading to 14.04.1 and rebooting, the luks encrypted root file system could not be unlocked. The system would prompt for the password, but then throw a bunch of errors, with the most notable "/sbin/cryptsetup not found".
I then booted off the 12.05.5 install media (14.04.1 would could not properly unlock the luks encrypted file systems) and created the /usr/share/initramfs-tools/conf-hooks.d/forcecryptsetup as described in comment #4, updated the initrd, and rebooted. I was then prompted for the password, which was accepted and opened the root file system. All is good again after upgrading! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1256730 Title: /usr/share/initramfs-toos/hooks/cryptroot does not honour the CRYPTSETUP variable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1256730/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
