E: Unable to locate package apt-transport-https

[Stein-Erik]

I am following the procedure on this web page:

  https://www.phusionpassenger.com/library/install/apache/install/oss/jessie/

More specifically, it says:

 These commands will install Passenger + Apache module through
 Phusion's APT repository.


      # Install Phusion PGP key and add HTTPS support for APT
    apt-key adv --keyserver hkp://keyserver.ubuntu.com:80
                --recv-keys 561F9B9CAC40B2F7
    apt-get install -y apt-transport-https ca-certificates

...

However, I get an error that I didn't get about a week ago:

The problem is the 'rm -rf /var/lib/apt/lists/*'. By deleting those files, 'apt-get install' does not work.

Thanks a lot - that was it.

I was adding 'clean up' commands to make the docker image as small as possible.

I'll restructure it to only do that command at the end of all apt installations.

Best regards,
