Mobian

Mobian is a project to port the Debian GNU/Linux distribution running the mainline Linux kernel to smartphones and tablets.

[4] Droidian (previously known as hybris-mobian) is a version of Mobian which runs top of Android's variant of the Linux kernel and the Libhybris and Halium adaptation layer, and works with devices which are supported by Ubuntu Touch.

[6] As software stack Mobian uses the Phosh (Phone shell) graphical system developed by Purism, which is based on GTK.

[18] In June 2020, writing for Fossbytes, Sarvottam Kumar wrote about how Mobian aims to bring Debian 11 Bullseye to mobile ARM64 devices by creating custom images for installation.

[19] In July 2020, Jean-Luc Aufranc in CNX Software article called it "a work in progress" he said it was "interesting" that it uses Purism's Phosh interface, and while it includes many apps, several functions were broken or unreliable.

[23] In September 2021, in a detailed review of PinePhone for Hackaday, Bryan Cockfield wrote about experimenting with, and switching to Mobian, or "mobile Debian".

He called the ability to SSH into it like any other computer and install software with apt "excellent features" which "worked surprisingly well" for the Kodi media player.
