This question is posted as a follow on the the missing GPG keys Q I posted here: Many of my signatures/public keys for my repos dissappeared!

Here is the output when trying to apt-get update:

Err http://ppa.launchpad.net maverick/main Sources
404 Not Found Err http://ppa.launchpad.net maverick/main i386 Packages

E: Some index files failed to download, they have been ignored, or old ones used instead.

I'm not sure how or why these errors have come about or how to fix.

Any help appreciated.

Can you edit your question and tag it with whatever version of ubuntu you're running? –  Jorge Castro Apr 20 '11 at 14:27

@Jorge: I think he's running Maverick, seeing gb.archive.ubuntu.com maverick. –  Lekensteyn Apr 20 '11 at 14:36
    
Ah right, I thought this might have been a typical "ppa's not ready yet for 11.04". The VLC one is obviously out of date, can't explain the others though. –  Jorge Castro Apr 20 '11 at 14:46
    
This question appears to be abandoned and unanswered, could you perhaps add more detail to your question? If this question no longer applies then you can either delete it or answer it yourself if you've solved the problem. Thanks! –  Jacob Johan Edwards Jan 29 '12 at 23:16

The problem is not really about GPG keys, but if you look at the output you will find a lot of "404 Not Found" errors. Looks like some repositories were removed or you're having trouble connecting to the LaunchPad servers.

BTW to fix that one key you can try this (it won't solve the 404s):

gpg --keyserver keyserver.ubuntu.com --recv 3ACC3965 && gpg --export -a 3ACC3965 | sudo apt-key add -

I ended up just deleting the vlc nightlies and webd8 repos and the others miraculously sorted themselves out :D
