@cngirwa we need wait a reply from an UVdesk staff member, this can take time.
If you have not tried yet and if you can try, you can download the zip file of UVdesk already ready to be installed by running the wizard on the web browser.
The zip file ready for wizard can be downloaded here:
https://cdn.uvdesk.com/uvdesk/downloads/opensource/uvdesk-community-current-stable.zip
Once unzipped on your server you can follow just the web wizard procedure.
If you need help with the docker compose installation you need wait an UVdesk staff member reply if you have success with the suggested way you can update this discussion to inform us.
Have a nice time
