This whole thing happens because the libreoffice 5.3 packages use versioned "Provides:", but apt in Ubuntu 14.04 is too old and does not support these yet.
According to the changelog, "versioned provides" where added in apt 1.0.7, but Ubuntu 14.04 ships with apt 1.0.1. To solve this issue, the libreoffice packages for Trusty must either stop using versioned provides, or apt in Trusty must be updated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1662227 Title: Error with command "apt-get update" when using libreoffice PPA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1662227/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
