I tried launching ntpd with root adding the specified options, but it
actually returns the following issue:

ntpd[1162]: Command line: ntpd -g --panicgate
ntpd[1164]: proto: precision = 1.746 usec (-19)
ntpd[1164]: getconfig: Couldn't open </etc/ntp.conf>: No such file or
directory ntpd[1164]: unable to bind to wildcard address :: - another
process may be running - EXITING

couldn't simply kill the running process since it would respawn
instantly.

Indeed i didn't update root's profile since this system's
installation back on Jul 22!

I imagine reason why pull generations only shows the last  one:

The new generation actually introduces two unexpected elements:
a. At the login section it proposes both gnome and mate environment
(which is correctly usable only the latter)

b. Once i login on Mate's de, i'm unable to use any menu's application
(suggests something similar to "unable to spawn proccess
gio-launch-desktop - missing directory")

I wonder if i actually performed corectly root's commands, by accessing
it via "sudo su -", is it the right way? (i remember there was a better
one but couldn't find it on the manual)

As you suggest i'll bring this quest onto irc so i can solve it
in shared mode

Grazie mille!
