Any ideas what might resolve this?
Error - Perl execution failed
Undefined subroutine &main::authentic called at /usr/share/webmin/authentic-theme/index.cgi line 10.
PS: My Joomla installation was complaining that it wasn't updating security fixes because it needed php7 and php7 wasn't available from the jessie repository.
[SOLVED] (or at least ameleorated with a kludge)
I regenerated the webmin certificate as per the last response to a similar symptom:
https://www.virtualmin.com/node/47644
which was, just for the record since it is so useful:
openssl genrsa -des3 -out webmin.key 1024
openssl rsa -in webmin.key -out webmin.pem
openssl req -new -key webmin.key -out webmin.csr
openssl x509 -req -days 365 -in webmin.csr -signkey webmin.key -out webmin.crt
cat webmin.crt >> webmin.pem
cp webmin.pem /etc/webmin/miniserv.pem
/etc/init.d/webmin restart
