Sorry doesn't work either, get now ./setup.sh: line 321: /1031.os: No such file or directory
well the strange thing is that webmin has nearly the same script, and that one installs fine without any problem. so i really am astonised about why usermin won't do it.
the output is empty, i run the latest version of MacOS Catalina beta and when i tried to install it on a clean system it made a directory in the etc/tmp directory called .webmin
yes there is a /tmp folder on my system
Installation problem with Usermin on latest MacOS
