To add to Andrew's solution, in my case, the UUID in /etc/initramfs- tools/config.d/resume was correct. But my swap was on an LVM partition.
I have found this blog post: https://www.hiroom2.com/2018/05/01/ubuntu-1804-lvm-swap-wait-for-root- en/ and changed the line in /etc/initramfs-tools/config.d/resume from using UUID to using device path of LVM swap partition, i.e.: from something like: RESUME=UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx to something like: RESUME=/dev/mapper/ubuntuvg-lvswap After that, sudo update-initramfs -u Then restart and the problem was solved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1685794 Title: Boot delayed for about 90 seconds until 'random: crng init done' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1685794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
