Install / downgrade specific version of Node.js

Question

I have this:

RUN curl -sL https://deb.nodesource.com/setup_11.x | sudo -E bash -
RUN apt-get install -y nodejs=11

but I get:

E: Version '11' for 'nodejs' was not found

I also tried:

RUN apt-get install -y nodejs=11*

does anyone know how I can find out which versions are available? The problem is that node version 12 is already installed on this machine and I want to downgrade the Node.js version here.

Solution

Because 12 is already installed, I had to do this:

# apt-get remove -y nodejs  # key part
# curl -sL https://deb.nodesource.com/setup_11.x | sudo -E bash -
# apt-get install -y nodejs

This does not answer the question, as a specific version was requested.
