Undefined subroutine &main::get_miniserv_config

[Travis Farmer]

i just installed Webmin on one of my servers (running Fedora 33 Linux), but i seem to get an error, though my two other servers still run webmin just fine. i suspect a missing perl module, but i don't know what it could be.
full error is:
Undefined subroutine &main::get_miniserv_config called at /usr/libexec/webmin/authentic-theme/session_login.cgi line 17.

i installed via the YUM repo for webmin.

Thanks in advance for any help.

Hi, Travis.

Have you installed it with .rpm package? If so, Fedora 33 has a small change in default Perl packages distribution.

Try the following:

dnf install perl-File-Basename perl-lib perl-Authen-OATH

Добрый день Илья. Получаю эту ошибку при входе в панель Webmin:Good afternoon, Ilya. I get this error when logging into Webmin panel:

Error - Perl execution failed
Undefined subroutine &main::get_miniserv_config called at /usr/share/webmin/authentic-theme/session_login.cgi line 15.

После обновления темы в Webmin

Смотрел решения:

After updating the theme in Webmin

но ни одно мне не помогло. Webmin + Virtualmin + NGINX + Ubuntu 20.04

Буду благодарен за помощь!

but none helped me. Webmin + Virtualmin + NGINX + Ubuntu 20.04

I would be grateful for your help!

Добрый вечер, Женя.

Самым простым вариантом будет установить devel версию Webmin 1.971:

wget https://download.webmin.com/devel/deb/webmin_current.deb
apt-get upgrade ./webmin_current.deb

Да, я так и сделал. Большое спасибо!
