Dear Maintainer,

I have installed Debian Buster and Bullseye as a VM on two different
host PCs and have noticed that when I choose to install the LXQt DE the
VM will be assigned two IPv4 addresses, visible from the `ip a` command.

In both cases the hypervisor was KVM. At no point did I set up a static
IP address, I simply allowed the installer to set up the network
automatically. At first I believed I had mis-configured something or
installed an unusual package, but the same issue happened on a clean
install, where the very first thing I did was open a terminal and check
`ip a`.

This has affected my other hosts on the network because name resolution
will sometimes fail. I am nearly certain this must be some sort of issue
with choosing to install LXQt from the installer. I do not have any sort
of unusual IP assignments on my network from any other operating system,
including Debian installed without LXQt.

Thanks for your time,
Ali Homafar

You can fix this issue by removing "/etc/network/interfaces":
sudo rm /etc/network/interfaces

To avoid problems with DNS, remove also "/etc/resolv.conf":
sudo rm /etc/resolv.conf
