Today I have tried to install proot PostMarket os, but then i tried to run script to launch x it give me an error:"Error: proot-distro should not be executed as root user.". I had hope that it was an only one distributive error and i tried to install clear alpine, but it gave the same error.
Later i tried the Arch, but it gave the same error.
(I dont have root on my phone)
(I attached arch screenshot)

P.S after each installation i cleared termux data

It appears you're running proot-distro somewhere other than Termux. You cannot install proot-distro inside of a proot OS image. If you're on a standard version of Linux, you should create a non-privileged user (other than root), and re-run proot-distro.
