Could you please post the output of the following:
ls /etc/modprobe.d
Thank you.
Thanks a lot for suggestions. I've solved the problem in the following way:
First, I typed the following command
sudo ifup eth0
and I got the answer:
Ignoring unknown interface eth0=eth0
Then I asked the google, how to configure eth0 in Kubuntu and I followed instruction I found in
http://
I edit the file /etc/network/
# The primary network interface - use DHCP to find our address
auto eth0
iface eth0 inet dhcp
Then I restart networking services using the following command
sudo /etc/init.
Network is now working without a problem.
However, I am a bit disappointing that I have to correct the file /etc/network/
Note, that after upgrading, the /etc/network/
auto lo
iface lo inet loopback
