Job for vboxweb.service failed

I installed Virtualbox in terminal and even though the installation finished I noticed these 2 errors that might affect future releases.

Can't load /var/lib/shim-signed/mok/.rnd into RNG
139802536203584:error:2406F079:random number generator:RAND_load_file:Cannot open file:../crypto/rand/randfile.c:98:Filename=/var/lib/shim-signed/mok/.rnd

Job for vboxweb.service failed because the service did not take the steps required by its unit configuration.
