Last night my system(Ubuntu 12.04) was crashed, and I had to install the Ubuntu 12.04 again.
Actually I have "/var/cache/apt/archives", that it's for my previous OS ,but when I wrote this command as a root user :
sudo dpkg -i /var/cache/apt/archives/*deb
after several times show me this error :
system halted because there were too many errors...
and my Ubuntu didn't boot again, so I installed it again, now how to use
/var/cache/apt/archives and is there any way to handle this problem please ?
