I keep getting a red triangle at the top right corner of my screen that says I need to update my software, but when I run update manager, I get an error window with the title of this post saying the following in its details:

"W:Failed to fetch http://ppa.launchpad.net/plippo/t10lmt/ubuntu/dists/natty/main/source/Sources 404 Not Found
, W:Failed to fetch http://ppa.launchpad.net/plippo/t10lmt/ubuntu/dists/natty/main/binary-i386/Packages 404 Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead."

I tried following the instructions in this post http://ubuntuforums.org/showthread.php?t=1787167, but even though I successfully switch servers, I still get the same update manager failure.

That's because your using a ppa. The location has changed. Look at http://ppa.launchpad.net/plippo/t101mt/ubuntu/dists/natty/main/binary-i386/

Open Update Manager > Settings > Other Software and delete any reference to

plippo/t101mt

Then add to:


ppa:plippo/t101mt

Close and let it update.

So doing that didnt help, but it turned out that instead of t101mt, my path had t10lmt - no idea how the 1 got mixed with an l since i never edited it manually ... but it did.

So just changing the l to an 1 fixed the first two errors, but now I still get this error when reloading the package manager:

W: GPG error: http://ppa.launchpad.net natty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C3745BE8983882DF

OK, so I used the link below as an example to deal with the missing key error.
