Repositories: Link does not exists

I use OpenSuse 13.1 32 bits

When I try to update my PC software, with Apper, a message appears saying that the link bellow does not exists:

http://download.opensuse.org/repositories/LibreOffice:/5.0/openSUSE_13.1/

Where and how do I solve this problem?

Hi
Delete the repository, it’s moved to 5.1 and no build for 13.1;
http://download.opensuse.org/repositories/LibreOffice:/5.1/

13.1 has moved to Evergreen which ends in November, openSUSE:Evergreen - openSUSE Wiki
