I'm completely new to Ubuntu and linux/unix/open source operating systems/etc. and am having some difficulty getting acclimated. Is this a good place to ask questions? For one thing, I am unable to install any plugins. Permissions are denied. Secondly, drivers give me a similar issue. I'm trying to access my wireless router using wifi, but Ubuntu does not recognise my wireless card though it did when I was using the live CD. Problem is, though, it won't let me install the drivers necessary. Also, when installing Adobe flash, it refuses to do so. When I try to manually move the necessary flash plugin to the proper folder, it also refuses. What gives?
