I'm working in Ubuntu Bionic Docker image and am in need of the libcxx-serial-dev package, but this only seems to be available in the Debian repos. How do I go about installing this package on Ubuntu 18.04?
I tried adding the following to my /etc/apt/sources.list
:
deb http://deb.debian.org/debian main
but then I couldn't find the public key for the repo.
Does anyone know how to solve this?
