Re: [webmin-l] IPTABLES issues on Xubuntu 18.04.1 and laptop

[Joe C. <jo...@vi...>]

Ubuntu 18.04 uses a new network configuration system called netplan. 
Webmin does not yet fully support it (Webmin devel version 18.91 has 
some support, but there are still bugs and missing bits).

You'll either need to switch to the previous network configuration 
scripts, or wait for support in Webmin to be finished.
