Hi,
All webmin upgrades I have performed until now (at least 5) failed to install the third party module I use for the exim mail server. Not a big problem, but annoying. Annoying because you see the upgrade process checking for other modules.

Is this the only third-party module you have installed? If you have others, do they get skipped as well?
Also, how did you install Webmin - from an RPM, Debian package or tar.gz?
Finally, what does the following output on your system :
grep root= /etc/webmin/miniserv.conf
