Answer 1

It can be a DNS problem too. Can you update resolv.conf by:

sudo nano /etc/resolv.conf

and then add these lines to the file:

nameserver 8.8.8.8
nameserver 8.8.4.4

which would use Google's DNS server.

Save and reboot and try the apt-get command again and see if this helps.

Answer 2

Disable Avast!!!

Avast Firewall or some shield was messing up with me...
