I'm running a new installation (2024.12.0) on Docker, following the instructions on the website. If I set CPAD_INSTALL_ONLYOFFICE to yes I get:
fatal: invalid reference: 4f370beb
If I disable CPAD_INSTALL_ONLYOFFICE and exec into the container, it appears that /cryptpad/onlyoffice-conf/onlyoffice-builds.git contains no refs at all; at least when I run git show-ref from that directory it shows nothing.
I tried this with the image I built from the instructions and the cryptpad/cryptpad image on Docker Hub.
Here’s a log of what happens when I run the install-onlyoffice.sh script with bash -x.
