Passing this along to Joe for review.

It looks like you're seeing the issue described in the post here:

https://www.virtualmin.com/node/53493

Could you try the solution there in the first post and see if that works for you?

If that does indeed resolve it, we'll have to look deeper into that, as that should have been resolved long ago, I'm not quite sure why that would be occurring.

I already read that post before reporting. Here are the results:

Solution 1 - It is not a solution

Using command "virtualmin-config-system --exclude"

root@server:~# virtualmin-config-system --exclude
Option exclude requires an argument
Usage:
    virtualmin config-system [options]

      Options:
        --help|-h          Print this summary of options and exit
        --list-bundles|-s  List available installation bundles
        --list-plugins|-p  List available plugins
        --bundle|-b        A bundle of plugins to execute
        --log|-l           Path to a file for logging actions
        --include|-i       One or more extra plugins to include
        --exclude|-x       One or more plugins to exclude
        --test|-t          Test services after configured (when available)

Command "virtualmin-config-system --list-plugins"

root@server:~# virtualmin-config-system --list-plugins
Available Plugins:
  AWStats            Apache             Bind               ClamAV
  Dovecot            Fail2ban           Fail2banFirewalld  Firewall
  Firewalld          Mailman            MySQL              NTP
  Net                Nginx              Postfix            PostgreSQL
  ProFTPd            Procmail           Quotas             SASL
  SELinux            Shells             SpamAssassin       Status
  Upgrade            Usermin            Virtualmin         Webalizer
  Webmin

Command "virtualmin-config-system --exclude Fail2banFirewalld" not working root@server:~# virtualmin-config-system --exclude Fail2banFirewalld Usage: virtualmin config-system [options]

Options: --help|-h Print this summary of options and exit --list-bundles|-s List available installation bundles --list-plugins|-p List available plugins --bundle|-b A bundle of plugins to execute --log|-l Path to a file for logging actions --include|-i One or more extra plugins to include --exclude|-x One or more plugins to exclude --test|-t

Solution 2 - It is not a solution. I tried editing /usr/share/webmin/init/init-lib.php and using all combinations possible in that if statement. Here are all combinations used:

(!-r "$config{'init_dir'}/$_[0]" || &is_systemd_service($unit))
(!-r "$config{'init_dir'}/$_[0]" || !&is_systemd_service($unit))
!(-r "$config{'init_dir'}/$_[0]" || &is_systemd_service($unit))

Solution 3 - I did not find a file called S99fail2ban in any of rc.d directories. The only file is K01fail2ban

Those "tips" mentioned in that post are not solution to apply in this case. I couldn't manage installing Virtualmin in a VMware workstation 15 with Debian 64-bit. I would like to exclude the packages Fail2Ban, Fail2banFirewalld and Firewalld to see if I can install it, but I don't know. A lot of garbage remains behind with every installation failure.

I need a solution as soon as possible.

Doing a research fail2ban-firewalld is not a package in Debian. Only Fedora/CentOS/RHEL have this package. Under this circumstances I am wondering why there is a Virtualmin package named Fail2banFirewall?

For those like me who don't use Firewalld after a succeed installation just disable firewalld service. Do not remove it from system. You can use iptables as before (old school).

This is a bug in Debian 9 installation. Virtualmin is not enabling Firewalld service. Please do the following test and see the results:

Firewalld service disabled:

[1/2] Configuring Firewalld                                             [  ✔  ]
[2/2] Configuring Fail2banFirewalld                                     [  ✔  ]

As you may see if Virtualmin is not enabling Firewalld installation will fail with error in Phase 3 - Step 21.

Also fail2ban service should be masked. If it is not masked it won't let you configure Fail2banFirewalld.

Anyone can get rid off Firewalld just stopping the service. Then in jail.local switch from firewalld to normal banning.
