Whenever I tried to install synaptic or other libraries like sudo apt-get install git-core, etc... it's showing errors.
When it starts running but stops at 22% and also with many errors.
I am not able to install anything. When I tried to install synaptic using
sudo apt-get install synaptic
it says unable to locate package synaptic.
The internet connections are also working. firefox is working but I am unable to download anything through terminal.
