I create an Ubuntu Server VM in Proxmox (not a container), from the Ubuntu server ISO downloader from Ubuntu site.
Virtualmin script is running well and no error !
The /etc/network/interfaces exist : “interfaces” is empty.
it’s my install, base on Ubuntu ISO.
Network on this VM is NETPLAN setting
I don’t configure Netplan… It seems to be default network setting for Ubuntu Server 20.04 LTS.
Thanks.
now it works
but before it was NOT possible to “add a new interface” in the VM Ubuntu 20.04
simply because, without ANY interfaces, I cannot access to the Virtualmin web site…
So, I must first define the interface in NETPLAN in CLI with VI, apply the new settings, and now, YES I can access to Virtualmin “myserver.be:10000”.
Just another problem with the CONTAINER Ubuntu 20.04
Let’s Encrypt was not working (doesn’t succeed).
I solve it with “certbot register”
because Let’s Encrypt was trying to use an invalid email address.
No problem with LE and Certbot in the VM test.
Probably the install script was made the Let’s Encrypt setting another way…
