BYOC - Connect-AppVeyorToComputer: Error installing Host Agent

[HariSekhon]

On Debian 9 in docker (btw the terminal messes up every time due to some terminal escape codes it goes to the top of the screen and then overwrites output which makes it hard to differentiate).

Dependencies have already been installed successfully:

apt-get install -y libcap2-bin libterm-ui-perl sudo sysvinit-utils

Connect-AppVeyorToComputer: Error installing Host Agent

Why does the deb only get installed when calling Connect-AppVeyorToComputer and not by the install procedure of Install-Module AppVeyorBYOC -Scope CurrentUser -Force?

Is there a direct repository where the debian agent package can be installed from?
