    August 6, 2019

    Last night, I upgraded my host machine's operating system from Ubuntu 18.04.1 LTS to Ubuntu 19.04. In the first go, it felt nice having a new clean interface right in front, but very soon, I realised that the upgrade was a bit off, on my machine.

    1. I started learning Ansible (though a terrible start).
