Tried to install yesterday Onlyoffice (on Ubuntu 19). Installed via Docker. And using Apache. After some hickups (mainly getting it working with Apache) was able to create a docx file out of seafile. However when trying to edit only empty page was shown. And the file got a “locked by Onlyoffice” sign.
So I assume that I need to first uninstall Office preview (using Libreoffice) before I try another time to install Onlyoffice? Has somebody made this experience and can advise?
