Upgrading WSL2 to Ubuntu 20.04 and running Jekyll
Ubuntu LTS 20.04 just came out, and you can either install into WSL2 from the Windows Store, or if you already had Ubuntu for WSL then you can upgrade that in place using
sudo do-release-upgrade -d.
There’s a few confirmation prompts along the way. Eventually you’ll get to a point where it wants to reboot. The trouble is if you try
sudo reboot it will complain that you’re not running systemd and give up.
The solution is to jump back to Windows and run
wsl --shutdown, then relaunch Ubuntu and it should be happy.
Having a freshly upgraded install of Ubuntu, I thought it was time I got a local copy of Jekyll so I could preview my blog posts.
To ensure that I’m using the same Gems that GitHub Pages use, I updated my Gemfile to just reference the github-pages gem.
source 'https://rubygems.org' gem 'github-pages'
And then install Jekyll prerequisites:
sudo apt-get install ruby-full sudo apt-get install build-essential dh-autoreconf sudo apt install zlibc sudo apt install libxml2-dev sudo apt install libxslt-dev
Tell Ruby to install Gems locally (so we don’t need sudo)
echo 'export GEM_HOME=~/.ruby/' >> ~/.bashrc echo 'export PATH="$PATH:~/.ruby/bin"' >> ~/.bashrc source ~/.bashrc
gem update gem install pkg-config -v "~> 1.1" gem install nokogiri -- --use-system-libraries bundle install
