Reading package lists... Done

torger@ubuntu:~$

prepend sudo to apt-get install

I did: "sudo apt-get install" already.

I meant, run sudo apt-get install wormux . Your shell processes &&, so apt-get install is run not by sudo - and without root privileges. And, surely, fails.

I did :"sudo apt-get install wormux" already and got the error listed above.

As I understood, you made
sudo apt-get update && apt-get install wormux
in this case you get
sudo apt-get update
and then
apt-get install wormux
So apt-get install wormux is run without root rights. Inthe aove you got the message
E: Could not open lock file /var/lib/apt/lists/lock - open (13 Permission denied)
This rarely happens under root...

Thanks I got it installed.
