I've tried following the instructions from,
The first command,
"sudo add-apt-repository ppa:abhshk-btra/rotatingcanvas"
adds the repository and returns successfully.
The second command,
"sudo apt-get update"
"W: Failed to fetch http://ppa.launchpad.net/abhshk-btra/rotatingcanvas/ubuntu/dists/raring/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead."
I understand the failure easily enough, there are no files for 'raring'. How to proceed from here? Wait for the ppa to be updated, or is there another way to get the lens installed?
Thank you for taking the time to look at this,
