First, install Docker Community Edition.
Then, create a local working directory in your computer. Let's say its absolute path is given by absolute-path
Place all the required packages (i.e., rvgs-1.00.zip, src-1.00.zip, fonts-1.00.zip) in the local working
directory.
Now run the docker container as follows
docker run -it --rm \
-e USER=$$(id -u -n) \
-e GROUP=$$(id -g -n) \
-e UID=$$(id -u) \
-e GID=$$(id -g) \
-w /home/$$(id -u -n) \
-v `pwd`:/home/$$(id -u -n)/host \
diegonehab/vg
You should be dropped into Ubuntu 18.04 with everything installed, and a directory /home/<USER>/host
that mirrors the contents of your local absolute-path
directory.
Have fun.
