 +Secure boot: Signature verification failed for /​usr/​sbin/​xntpd
 +
 +This issue can be worked around by deleting the erroneous entry from the Trusted Signature Database (TSD) by running:
 +
 +trustchk -d /​usr/​sbin/​ntp4/​ntpd4
 +
 +If you are already hitting this problem, then you need to reduce your Secure Boot policy to allow boot.  Then, delete the TSD entry, set the Secure Boot policy back to a level of 2 or less, and boot one more time.
