It may be funny and the answer might be very simple but...I dont know how to do that.

You don't have the right permissions to extract archives in the folder "file:///opt"

you need administrative privileges (or "root privileges" as it's referred to) to do anything in the root file system.

A way around that using GUI apps is to open Nautilus (the default Ubuntu file browser) with root privileges, but be VERY careful with what you do!

to do that open up the run dialog by pressing ALT+F2 and type in:


gksu nautilus

this worked.

sudo nautilus

To install LAMP you can just do:


sudo tasksel install lamp-server
Doing it this way will make sure that it is kept updated.
