Fedora 31 CT looses network connectivity after dfm update and reboot

[atxrickyricky]

I've installed a container using fedora-31-default_20191029_amd64.tar.xz on Proxmox Virtual Environment 6.1-7


After I've installed the container with the above template and do a dfm update then reboot, I loose network connectivity. Here's an example...

If I update the network settings from within proxmox, the VM will update and work, however upon reboot it goes back to the above behavior.

Am I doing something wrong here? I'm relatively inexperienced with Proxmox but for the most part my experience has been rather straight forward.

Hi,

It's a bug [0], but you can fix that with command dhclient.

Thank you for the information Moayad. I'll keep an eye on that bug to see when it's fixed.
