I installed odoo 13 on ubuntu server 20.04, and I added the runbot module in it.

I added the odoo 13 repo from github and added also my custom module repo.

the test starts but it shows:

runbot have all the permissions to use docker,
i checked the default dockerfile used by runbot, and i noticed that it installs google chrome not an instance of odoo 13 to test my custom module in it.

I appreciate any given help.
