I'm following the directions here but:

"

E: Release file for http://http.kali.org/kali/dists/kali-rolling/InRelease is not valid yet (invalid for another 4h 35min 19s). Updates for this repository will not be applied.

"

So I googled that  and learned my clock was off and to restart ntp and other stuff. I googled how to do that and was directed here which resulted in

"

└─$  ntpdate -u "in.pool.ntp.org", sudo service ntp restart

ntpdig: lookup of in.pool.ntp.org, failed, errno -2 = Name or service not known
ntpdig: lookup of sudo failed, errno -2 = Name or service not known
ntpdig: lookup of service failed, errno -2 = Name or service not known
ntpdig: lookup of ntp failed, errno -2 = Name or service not known
ntpdig: lookup of restart failed, errno -2 = Name or service not known
ntpdig: no eligible servers"

"

I googled that and got no hits. I then shortened it to

"

ntpdig: lookup of in.pool.ntp.org, failed, errno -2 = Name or service'

"

but still no hits--
