this is most likely related to
https://bugs.launchpad.net/ubuntu/+bug/1779827
which causes /dev/urandom to go into blocking state until enough
entropy is seeded. any service or app that needs the random number
generator gets slowed down during boot due to this. a fix is in the
-proposed archive already and should land soon with the next kernel
update ...
(you should be able to speed up the boot by wiggling the mouse or
hitting the shift key a few times, that will increase the entropy much
quicker)
