Removing libs to make the server work - Why?

Why do I always have to rename/remove seafile-server-latest/seafile/lib/ and to make it work. Otherwise seafile server won’t start.

Currently I’m running ubuntu 16.04 LTS with seafile 6.2.3 but I have this problem for a very long time now since I started using seafile about two years ago with ubuntu 14.04 LTS.
