First of all, I do not use Ubuntu, I use Debian, but I thought it would be a nice input anyway, feel free to delete this if this don't help. I had the same problem the first reboot I did after a system update to:
Linux version 4.9.0-6-amd64 (debian-ker...@lists.debian.org) (gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1) ) #1 SMP Debian 4.9.88-1 (2018-04-29) Boot got stuck everytime at random: crng init, varying from 1min to 20min. A friend told me it was because the random pool was being populated everytime I booted and for some reason it was taking too long. I installed the havenge package (deb free repo) that contains an alternative algorithm to populate de RNG seeds. Apparently the problem is now solved, as my system is now booting in 13s. Hopefully this will be of some help. Anyway, if installing havenge does not work, you could purge it afterwards and no harm done... -- 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
