In s-tui 1.1.3-2.0, the run script /usr/bin/s-tui is missing. Only the files under /usr/lib/python3.10 are included in the package.

In the upstream Arch package the file is included: https://archlinux.org/packages/community/any/s-tui/

Rebuilding the package on a pentium4 machine resulted in a correct package. I cannot find any Arch Linux 32 specific PKGBUILD, so I’m not sure where this problem comes from. Maybe just rebuilding the package will fix it.
