Termux is awesome but the native environment is suffocating. I didn't even bother with Termux utilities after one hour of messing around. I went straight for the Arch Linux ARM proot environment and it contains ALL of the Arch Linux utilities. For example you will never get scipy to compile in normal Termux because you can't reasonably get a compatible Fortran compiler built and configured. Arch Linux ARM is the best "distro" within Termux and the installation script is seamless and supports multiple users!
