I've put them there once, and it didn't work. I'll try again then, thanks!
EDIT:
mustafa@ubuntu:~$ wget /home/mustafa/Desktop
/home/mustafa/Desktop: Unsupported scheme.
mustafa@ubuntu:~$ sudo dpkg -i gtk+-2.18.0^C
mustafa@ubuntu:~$
That's what I get. (I tried with asterisks and without)
Sometimes it asks for a sudo password, and I can't type anything.
WHAT AM I DOING WRONG? :'(
I bet there's an application that'll automatically install things, but you'd need to install it wouldn't you?
I'll make my own thread, to not disturb this one any longer.
