Here is the full series available to read on Mangadex (under a CC license), and direct link to Chapter 1 (of 16).

If you had never heard of this series before, Ubunchu! was published in the Official Ubuntu Magazine Japan periodically between the years of 2008-2013 (with some digital extras afterwards found in chapter 16 on mangadex). The series was released using a CC license and subsequent translations are also CC (plus the translators have directly communicated with the original author).

Praise open licenses

Chapters 1-8 were translated years ago, but the final chapter was only translated just a couple days ago.

Due to when it was written and published, it is a bit of a time capsule. You can relive some of the formative linux and Ubuntu events of the 21st century such as:

Unity Desktop

Unity is an alien

The rise of linux mint

Linux Mint as a JK

OpenOffice & LibreOffice

Battle lines are drawn in the office suite war to come

Ubuntu Touch

Ubuntu Touch, the third pillar of the mobile OS ecosystem
