Virtualmin will not start following package updates on my Ubuntu server

HTTP/1.0 500 Perl execution failed Server: MiniServ/1.981 Date: Sun, 8 May 2022 02:57:59 GMT Content-type: text/html; Charset=utf-8 Connection: close

Error — Perl execution failed

Undefined subroutine &WebminCore::getvar called at /usr/share/webmin/authentic-theme/authentic.pl line 59.

Virtualmin not running - need help


That indicates that:

  1. Webmin didn’t restart correctly (restart it manually by running /etc/webmin/restart command)
  2. Webmin version is outdated (latest available is 1.991)

Thank you Llia. You made my day. Webmin is back and now I’ll upgrade.

I’m glad it worked for you.
