Please help I'm trying to update to the latest release but the process is failing with the following LiquidSoap (LS) error which I can't seem to fix and I've been escalated to 2nd level support for a little while now with no response as yet.

Things I've tried unsuccessfully.

Changing the permissions and ACLs on the folder and folders above.
Changing the code to include SUDO command.
I've tried with using LS version 1.4.2 and 1.4.4.
Editing the update script and OPAM config files.
