Public bug reported: I’ve upgraded a server to bionic beaver, and it couldn’t boot anymore. Using the “recovery boot” option hanged a long time with the message "waiting for resume device".
Some googling lead be to the bug #206358, and I deduced that do-release- upgrade “messed with my swap” (as said by @aldebx on there). This was a LVM set-up with an encrypted swap, which may explain the bug. My workaround, form the root login of the recovery mode was the following 1. comment out the RESUME line in /etc/initramfs-tools/conf.d/resume 2. rebuild the initramfs with update-initramfs -u 3. mount the /boot partiton to actually put the initramfs on the correct place Now the systems boots again, but this problem shouldn’t have happened in the first place. ** Affects: initramfs-tools (Ubuntu) Importance: Undecided Status: New ** Tags: bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771000 Title: do-release-upgrade on a server with encrypted swap does not boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1771000/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
