I worked on the changes in the source code to create an up to day docker file of LibreOffice Online today. I had to adapt scripts to build the online version from source to LibreOffice Online for that and run it. Because the naming and the variable names of former scripts were changed with the fork I had to rework them.
I’m currently running the build process a second time and hope it will create a first version of a new LibreOffice Online docker container from source. Keep your fingers cross 😉
