How can I fix a 404 Error using a PPA?

When I try the software updater, it tells me that it Failed to download Repository Information and I should check my internet connection. Of course my internet works. The error it reproduces is below

W:GPG error: http://www.duinsoft.nl debs Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E18CE6625CB26B26,
W:Failed to fetch http://ppa.launchpad.net/eugenesan/java/ubuntu/dists/quantal/main/source/Sources  404  Not Found,
W:Failed to fetch http://ppa.launchpad.net/eugenesan/java/ubuntu/dists/quantal/main/binary-i386/Packages  404  Not Found,
E:Some index files failed to download. They have been ignored, or old ones used instead.`

How do I fix this?


This generally means that there is no PPA for the current version of Ubuntu you are running (quantal). if you go to http://ppa.launchpad.net/eugenesan/java/ubuntu/dists/ you will see PPAs for previous releases.

[DIR] maverick/ 19-Jan-2012 09:12 - [DIR] natty/ 19-Jan-2012 09:12 - [DIR] oneiric/ 18-Jan-2012 14:22 - [DIR] precise/ 19-Jan-2012 09:12

So you need to wait until a quantal PPA is added.

  • Thanks. Going to the software update settings and turning off the java ppa updates solved the issue.
