Upgrade from 20.04 to 22.04 failed with "Fatal: unexpected error from getentropy: Invalid argument"

[Koteswara Uppalapati]

Upgrade from 20.04 to 22.04 failed with "Fatal: unexpected error from getentropy: Invalid argument". We have fips-updates enabled thru Ubuntu pro subscription. Tried to upgrade from 18.04 to 22.04. Upgrade from 18.04 to 204 is successful but upgrade from 20.04 to 22.04 failed. Apt or do-release-upgrade commands no longer working after the upgrade failed so we have to restore the host to the Ubuntu 20.04 snapshots.
