ubuntu error message when updating

whenever I chck for an update I get the following error message:

W:Failed to fetch http://ppa.launchpad.net/cheleb/blender-svn/ubuntu/dists/precise/main/source/Sources  404  Not Found
, W:Failed to fetch http://ppa.launchpad.net/cheleb/blender-svn/ubuntu/dists/precise/main/binary-amd64/Packages  404  Not Found
, W:Failed to fetch http://ppa.launchpad.net/cheleb/blender-svn/ubuntu/dists/precise/main/binary-i386/Packages  404  Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead.

How can I fix this?

That ppa is currently empty:
https://launchpad.net/~cheleb/+archive/ppa/+packages?field.name_filter=&field.status_filter=&field.series_filter=

Delete it from your ppa list.

Thanks a lot.

But how can I delete it from the ppa list?

Launch software-properties-gtk from the terminal with sudo software-properties-gtk (or you can find it under System > Administration > Software Sources, depending on which desktop environment you're using), then click on the second tab, named "Other software"). There you'll find your additional repositories. You can deselect or remove the dead repository from there. Then close.
When you're done, from the terminal sudo apt-get update
