Some of you may have noticed that Ubuntu 14.04 Server Packages are gone.
Here are the reasons for that decision:
- Support policy: latest 2 releases + LTS
- Ubuntu 14.04 comes with PHP < 5.6 which is not supported in current ownCloud server versions
If you need to stay on Ubuntu 14.04, upgrade to a newer PHP version (preferably 7.1) and use the manual/tarball upgrade.
