Unable update BeagleBone Green

[claudio...@gmail.com]

In order to install the ntpdate program, I would like to update the linux version (Debian GNU/Linux 8.8 jessie).
I get the following errors:

Both of these issues can be caused by not plugging in the Ethernet cable..

By default we have jessie builds configured to use systemd-timesyncd,
this replaces the userspace tool "ntpdate". systemd-timesyncd will
keep the clock up-to date, as long as you have open internet
connection.

I have insert new nameserver in etc/resolv.conf:

 

nameserver 212.27.32.176

nameserver 212.27.32.177

nameserver 8.8.8.8

 

But this don’t work (..and the file resolv.conf don’t store the new configuration; when I restart the beagleBone, the nameservers are not present)
