Ubuntu Server requires LibreOffice to run richdocumentscode in NextCloud
On Ubuntu Server running a snap package of Nextcloud it looks like the only way to get the Collabora Online - Built-in CODE Server to work is to downgrade it to v6.4.608. Installing a higher version causes it not to function. see topic
I found out that on desktop variants this is not the case and it runs fine out of the box. So I thought why not install LibreOffice on Ubuntu Server and see what happens… and right after that the latest version of richdocumentscode is running fine.
I unfortunately don’t have to expertise to narrow this down to a single dependency, but it does look like after v6.4.608 a dependency is introduced from LibreOffice that causes it not to run on systems without LibreOffice installed.
I can second this, I had the same issue but when attempting to downgrade the server stopped working, so I found your issue post here and installed libreoffice on my Debian server and it fixed the whole issue.
I also agree with your consensus of a new added dependency that is not there. The dependency needs to be identified and added to the AppImage for the builtin CODE server.
Actually, installing libreoffice did not actually seem to fix it for me, or it only worked for a short while (but that don't make too much sense). I'll start scanning over logs once I get some spare time.
