It would appear this message comes from: eval $(fstype < "$NEWROOT")
on line 295 of: /usr/share/initramfs-tools/scripts/local-top/cryptroot It seems to be a timing issue. An extra udev_settle seems to fix it: udev_settle eval $(fstype < "$NEWROOT") Then rebuild the initramfs: update-initramfs -u To be honest I'm not exactly sure it's udev it's waiting for or whether this just introduced a delay. I don't expect it to fix much apart from the message. I still had a bootable system even with the message. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1273261 Title: Cryptsetup error during boot: /scripts/local-top/cryptroot: line 1: can't open /dev/mapper/ubuntu--vg-root: no such file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1273261/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
