In 18.04.1 Server, I was able to freshly install with two luks encrypted devices which I already added during the partitioning step.
Later on, I changed the generated /dev/mapper/... names in /etc/crypttab and /etc/fstab and continued with a dmsetup rename OLD_NAME1 NEW_NAME1 #avoids errors in later commands dmsetup rename OLD_NAME2 NEW_NAME2 #avoids errors in later commands update-initramfs -c -t -k all update-grub reboot Both update-* commands ran without issues. The result was that I get asked for one of the two passwords and then it gets into some lvm loop and fails booting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1525724 Title: boot hangs with more than 1 luks device in crypttab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1525724/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
