Getting a deb repository error for collabora

Question

I'm brave enough to try out the upgrade from wheezy to jessie on my pi according to this: Upgrade to Raspbian Jessie

So far it runs pretty smooth, except that I get an error when updating the repositories here:

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

Any idea? It does not seem to break anything really, but I still would like to resolve the error.

Answer 1

As far as I am aware collabora is still using wheezy based software, it has not been upgraded to jessie.

If you want to use that repository change its entry back to wheezy from jessie.
