Bug Description
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-
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.
