I am very new to Ubuntu and couldn't find a straight forward answer or solution to this:
- I'm running Ubuntu GNOME 13.10 and I have installed Tweak Tool. Running fine.
- I've downloaded the MediterraneanNight Series 2.03 theme and extracted it to the desktop.
- I have enabled viewing of hidden files and located /usr/share/themes, I can see the existing theme files located inside: Adwaita, HighContrast etc
- The problem - I cannot drag and drop the newly extracted theme into the theme folder. I have located the permissions tab via theme folder properties, this indicates Owner and Group as root, Others has no value. All three drop-downs are transparent/faded and inaccessible. 'You are not the owner, so you cannot change these permissions'.
How can I solve this please?
