I installed Oc using Linux distribution packages. Since about one month the update is failing giving a 404 Error Message:

Err http://download.owncloud.org/download/repositories/stable/Debian_8.0/ owncloud 10.0.0-1.1

I already readded a fresh link from the Oc website to the sources.list. But it won't work. There wasn't a problem updating for over 2 years and nothing changed.
Does somebody have an idea?

http://download.owncloud.org/download/repositories/stable/Debian_8.0/all/
should contain

[ ] owncloud-deps-php5_9.1.5-1.1_all.deb 2017-04-19 14:26 4.6K
[ ] owncloud-deps-php7.0_9.1.5-1.1_all.deb 2017-04-19 14:26 4.6K
[ ] owncloud-files_9.1.5-1.1_all.deb 2017-04-19 02:18 23M
[ ] owncloud-wildcard-trusted-domains_0.1-7.1_all.deb 2017-03-30 17:07 1.6K
[ ] owncloud_9.1.5-1.1_all.deb 2017-04-19 14:26 2.8K

For 10.0 you need http://download.owncloud.org/download/repositories/10.0/Debian_8.0/all/ with
[ ] owncloud-deps-php5_10.0.1-1.1_all.deb 2017-05-22 23:05 4.8K
[ ] owncloud-deps-php7.0_10.0.1-1.1_all.deb 2017-05-22 23:05 4.8K
[ ] owncloud-files_10.0.1-1.1_all.deb 2017-05-22 22:53 23M
[ ] owncloud_10.0.1-1.1_all.deb 2017-05-22 23:05 3.0K

Thanks alot. Had to clear apt cache. Don't know why apt wanted to update to 10.0 with the wrong repository.
Problem's fixed.
