Running PostmarketOS on Android Termux proot without a custom ROM (2024) (opens in new tab)

I actually tried to get PMOS support upstreamed: https://github.com/termux/proot-distro/issues/429 But unfortunately they didn't think it was different enough from Alpine and I didn't have the cycles to argue the point at the time. It would be really nice to get all of this packaged up to the point of being like 3 commands to go from just termux to a full PMOS on your Android phone, but it's a lot of different bits to get working together.

Did anyone manage to install a Linux OS with proper desktop inside your Android phone?

I tried a lot of open source tools written for this with Termux but when I tried to use it via vnc, I got a black screen and there was a black plus or dot iirc.

I guess I'm wondering what the advantage is with this over something like a proot-distro ubuntu distro running

or what specific use cases that ubuntu / android / termux wouldn't otherwise cover

(or really just use cases in general here)
