If you want to administer Linux you need intensive Terminal training.
You have to know a huge number of command names.
Once you know the name, you can try to use the "man" pages to work out how to use it (or do an Internet search).
IMO, the GUI tools that I've used are generally only 50% finished.
Compare Nautilus to Windows Explorer.
Nautilus has some good features (tabs, multi-level copy/cut/delete ability) but its screen tips are poor and it didn't want to sort files unless I was in "List" view.
Windows Explorer's screen tips are better (even though MS purged some info from them - comparing W7 to XP) and it sorts and groups in the views I use ("Details" and "Large Icons")
I had an update problem last week (open office email merge) on my Ubuntu VM (my actual Ubuntu install didn't have any problems though).
The update wouldn't install, stalling the update process (after an hour, it still hadn't installed the 10KB update).
I don't use OO anyway, so I thought I'd remove the email merge section.
I couldn't purge it either (using Synaptic, apt-get or dpkg).
The problem was only solved, because my friend knew about a command called "fuser" (I'd never heard of it).
