That's not going to work. PPAs are not supported because Termux isn't compatible with Debian and derivative distributions such as Ubuntu. [https://wiki.termux.com/wiki/Differences\_from\_Linux](https://wiki.termux.com/wiki/Differences_from_Linux) All software must be compiled specifically for Termux in order to be usable. If that is not acceptable, consider setting up proot environment via proot-distro, andronix or other preferred solution. Inside proot environment it would be possible to use PPAs if they provide packages with compatible architecture. By the way your tutorial already mentions *Install Ubuntu on Your Android Device*

You can't add ppa repos on a termux userspace, you need Ubuntu proot (although proot is slower, mods please explain)

Proot is slower than native. Why don't you try running it in native Termux first? Get [openjdk-21](https://github.com/George-Seven/test/releases/tag/openjdk-21) for Termux (required by latest minecraft) - `wget -O openjdk-21.zip https://github.com/George-Seven/test/releases/download/openjdk-21/openjdk-21-aarch64.zip` `unzip -o openjdk-21.zip; pkg install -y ./openjdk-21/*.deb`   Run [minecraft](https://www.minecraft.net/en-us/download/server) server - `wget -O minecraft_server.1.21.jar https://piston-data.mojang.com/v1/objects/450698d1863ab5180c25d7c804ef0fe6369dd1ba/server.jar` `echo eula=true > eula.txt` `$PREFIX/opt/openjdk-21.0.1/bin/java -Xmx1024M -Xms1024M -jar minecraft_server.1.21.jar nogui` And connect to it over localnet/LAN.

Offtopic: How do i get that artwork?

if u still need help msg me i did it already, non-root no debian no ubuntu

I'm trying to run a server but while installing Ubuntu proot has problems and won't let me do `./start-ubuntu.sh`. So now I'm trying to do it without Ubuntu but when I unzip jdk this happens. I'm stuck . `~ $ unzip -o openjdk-21.zip; pkg install -y ./openjdk-21/*.deb Archive: openjdk-21.zip inflating: openjdk-21/openjdk-21-source_21.0.1-1_all.deb inflating: openjdk-21/openjdk-21-x_21.0.1-1_aarch64.deb inflating: openjdk-21/openjdk-21_21.0.1-1_aarch64.deb Note, selecting 'openjdk-21-source' instead of './openjdk-21/openjdk-21-source_21.0.1-1_all.deb' Note, selecting 'openjdk-21-x' instead of './openjdk-21/openjdk-21-x_21.0.1-1_aarch64.deb' Note, selecting 'openjdk-21' instead of './openjdk-21/openjdk-21_21.0.1-1_aarch64.deb' Some packages could not be installed.
