I've just installed the Linux Mint 14 Mate, 64bit version. I wasn't really happy with the graphics, so I've tried ti install a new theme, but it happened that I've followed this post (http://linuxmint-art.org/content/show.p ... ent=134123), and had to stop rightaway after "adding" the repository.
This was the message I got after the apt-get update:
W: Failed to fetch http://ppa.launchpad.net/nikount/orta-d ... ce/Sources 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/nikount/orta-d ... 4/Packages 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/nikount/orta-d ... 6/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
So, i guess that this repository which I was trying to add wasn't actually working at its top... So here's my question: How do I remove it?
I've tried to follow another post, which told me to use some kind of command "sudo ppa-purge ppa:smth/smth-else", and I've kinda installed it but it didn't happen to work.
(So, if I can even try a second question- How do I change the color of the bottom panel and menu without messing everything up?)
Hope someone can help me before i rainbows everything in this pc
