I have installed ISPCONFIG SERVER ON UBUNTU 12.04 DESKTOP. On update my mouse stopped working. Then I run a command sudo dpkg --reconfigure -a sudo apt-get upgrade. It took lot of time to reconfigure, after I restarted the system, now mouse is still not working and I am faced with another problem. My networking fails to start. I am also getting this error on start modprobe:fatal : could not load /lib/modules/3.13.0-36-generic/modules - No such file or directory. Need a solution on this as I am really stuck and my server is as good as down without newtorking. Thanks.
