Yesterday I upgraded my Ubuntu by SSH but before I finished it, I restarted my computer.
I know that was not very smart. Anyway now I don't have internet connection, the WiFi or Ethernet is not recognized.

When I try on the latest version installed, the mice didn't work. When I try with previous version and go in gnome-network manager it's said:

The system network service is not compatible with this version

Another thing is when I comeback to the remote computer and look at the SSH terminal the process have stopped at:

Setting up desktop-file-utils (0.20-0ubuntu2) ... 

Configuration file `/etc/gnome/defaults.list' 

==> Modified (by you or by a script)

since installation. ==> Package distributor has shipped 

an updated version. What would you like to do about it ? 

Your options are: Y or I:install the package maintainer's 

version N or O : keep your currently-installed version D : 

show the differences between the versions Z : start a shell 

to examine the situation The default action is to keep your 

current version. * defaults.list (Y/I/N/O/D/Z) [default=N] ? 

Write failed: Broken pipe

Is there any simple solution other than I having to reinstall my system?
