In case it is helpful to anyone else, I found a resolution for my specific case. This askubuntu question helped: https://askubuntu.com/questions/1018907/ubuntu-installation-stuck-at- random-crng-init-done . In sum: sudo apt install rng-tools
About 1 week ago, my Ubuntu 18.04 boot time went from ~15sec to ~2min. When I looked at kern.log, every boot had something very similar to this in common: Jul 8 13:28:37 localhost kernel: [ 6.933299] IPv6: ADDRCONF(NETDEV_CHANGE): enp3s0: link becomes ready Jul 8 13:32:09 localhost kernel: [ 217.508340] random: crng init done After installing rng-tools (and just in case, updating initramfs and grub: sudo update-initramfs -u and sudo update-grub), my boot time returned to normal, ~15sec.
