I've installed Ubuntu recently and I've been trying to install some programs using apt-get but it never seems to work, not even apt-get update works, here's what I get when I try to install something, in this case: java's jdk-7 using:
apt-get install openjdk-7-jre-headless
here's what I get:

And it just get stuck at 0%
Edit: Yes, the internet is working fine on my system.
One thing I tried is changing the mirror server from which it's supposedly retrieving the packages from lb.archives.ubuntu.com to archives.ubuntu.com in /etc/apt/sources.list but it says that that file is read only and I can't make any changes to it.
I tried updating apt-get through
apt-get update
but I get this whenever I try to do that:
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
EDIT: Issue resolved, I wasn't using sudo apt-get update and was only using apt-get update
sudo apt-get update
?apt-get install
is still locking those files, do asudo ps ax | grep apt
and you should see the process that is locking those files. Try andkill -TERM
the PID, if not, do akill -9
.. then runsudo apt-get update
