If you SSH in as
root
and run/etc/webmin/restart
, does that fix the issue?Submitted by mrcheidel on Fri, 01/08/2021 - 00:50 Comment #2

Does it help if you logout of Webmin and login again? And refresh the page in your browser?

Dear Jamie Cameron I rolled back the system using the below commands:
wget http://prdownloads.sourceforge.net/webadmin/webmin_1.962_all.deb -P ~/
sudo dpkg --install ~/webmin_1.962_all.deb
rm webmin_1.962_all.deb
Now the system is restored and working on v1.962 The upgrade to 1.970 have any issue, I have upgraded my systems multiple times in the past and never has been an issue.. this case is different.
Thank you! mrcheidel

Hello,
Same problem and error message here with webmin 1.970 on Ubuntu 18.04.5 LTS
Regards,
When you restart Webmin does the pid change?
Is there a way to login and have a closer look? It mustn't be happening.
Okay, this issue has been reproduced and fixed.
It was tricky to find out the cause, as it only affected logins with sudo-capable users.
Webmin 1.971 will have it fixed. Meanwhile, you can manually apply the patch and restart Webmin.

For anyone seeing this, the 1.971 development release of Webmin from http://www.webmin.com/devel.html has a fix for this issue.

I have same issue phasing. Please suggest me with command line. I can't access webmin from my windows web browser. Please suggest me way forward with command. My webmin server install on centos 7. I found below mention error when i try to open my webmin server with windows web browser.
Error - Perl execution failed
Undefined subroutine &main::authentic called at /usr/libexec/webmin/authentic-theme/index.cgi line 12.
The fix would be is to install "development" version of Webmin 1.971 which fixes this error.
