Hi, I'm trying to install Docker on Tina (https://docs.docker.com/install/linux/docker-ce/ubuntu/) and I'm unable to setup their repository using add-apt-repository command:

Workaround
Add the repo manually to /etc/apt/sources.list

Happened to me as well. The '[ option=value ]' is rejected due to an incomplete regexp, below is how I fixed /usr/lib/linuxmint/mintSources/mintSources.py
