Downloading the Webmin installer from webmin[dot]com/download/webmin-current.tar.gz now should download version 2.111 released on April 16, 2024. Instead, version 2.110 is downloaded from prdownloads.sourceforge[dot]net/webadmin/webmin-2.110.tar.gz.
I tried two more times and got version 2.111 both times. I first witnessed the download error a few days ago. I have been testing a shell script I developed that installs Webmin including runtime dependencies on a FreeBSD system. On one occasion running the script twice a few minutes apart downloaded both version 2.110 and version 2.111, so it seems that something is behaving erratically.
