Did you ever hear how “great” Ruby is? If that is true, how come not many are (still) using it? Ruby is free software, i.e., it is free if you have free time! IMHO, Ruby’s most significant f*ing problem is “Just because version X works fine; version X+1 should work fine too!” Therefore, stick with version X until it is obsolete or vulnerable. Why use Ruby anyway? Because GitHub and GitHub Page were developed with it, so was Jekyll!

This page is about how to install Jekyll with Rbenv on a VirtualBox Debian Guest. Why Rbenv? Because This Is How Me Do It! If it works today, there is no warranty if it will still work the day after. Take it or leave it.

PS: For setting a VirtualBox Guest, visit https://osp4diss.vlsm.org/. I have spoken!

PART 1: SuperUser (root) Mode

VirtualBox Debian Guest Setting

Check how the NAT (Network Address Translation) redirects ports:

SSH: 127.0.0.1:6023 (host) to 10.0.2.15:22 (guest)
JEKYLL: 127.0.0.1:5000 (host) to 10.0.2.15:4000 (guest)

TAKE NOTE: Your NAT might be using other settings!

Settings in SuperUser (root) Mode

You need to have SuperUser (root) access for the first part of the installation. For the next part, just user privilege is needed.

assets/scripts/sources.list

Debian 11 (bullseye) package sources list file.

You might “copy and paste” that file or fetch it with:

wget https://doit.vlsm.org/assets/scripts/sources.list

Compare it with the /etc/apt/sources.list file on your Virtual Guest.

diff sources.list /etc/apt/sources.list

You need to have SuperUser (root) privilege (“su -“ or “sudo su -“) to replace the “sources.list” file.
