Going through the docker tutorial you linked before here, it seems like you are running an existing Docker container, rocker. This Docker container might not have the required stuff installed, so possibly worth trying the following also:

apt-get update

I've tried the following in my macOS command terminal:

docker run -rm -p 8787:8787 rocker/verse

Then accessing the opened instance of the image, I've entered the following in the RStudio embedded terminal:

git clone https://github.com/Hong-Kong-Districts-Info/dashboard-hkdistrictcouncillors.git
cd dashboard-hkdistrictcouncillors

From there, I switched to the R console and entered:

renv::restore()

Very similar steps to yours and got pretty similar message:

Generally, it might be more standard for me to create a Docker container specifically for this repo and then for people to use this container. I'll put that on our backlog.

Update

Fro discussing with @DataStrategyPro, work for me to start with base container, install packages and publish/share.
