Ok. So if I use the official installation method, I can just place (rsync) git clones of the plugins into the /plugins directory, run assets:precompile, and the plugins will be installed? If that is the case I will try and find a way to use the supported method (which won’t be easy because of all the restrictions the machine has in place).
As I’ve said. I can’t access (or install) any git repositories on the VM.
