As a side issue, I have discovered that, in the case of a Linux distribution that has ONLYOFFICE available only as a Flatpak, the location of the template is extraordinarily difficult to find. Here is where I found it after installing in Fedora 37 Cinnamon:
/var/lib/flatpak/app/org.onlyoffice.desktopeditors/x86_64/stable/b0617…/files/bin/opt/onlyoffice/desktopeditors/converter/empty.
For comparison, downloading and installing the RPM directly from the ONLYOFFICE website, the location is /opt/onlyoffice/desktopeditors/converter/empty. Far easier!
Understood, but I’m not sure that we can change it. This path in flatpak installation is related to flatpak hierarchy system of installed apps. We had to follow it to release the Desktop Editors on the flatpak.
Anyway, we are glad that you managed to resolve the issue. Please feel free to contact us if you face any issues.
