I recently downloaded and installed the Ubuntu 20.04.2 LTS pre-configured image file for the RPi, and am setting it up on a RPi4 8gb unit.
I was expecting to see the newer predictable/consistent network interface names, but instead it seems to default to the ‘old’ names like ‘eth0’ and ‘wlan0’.
I’m still a little confused as to why they (Canonical) would revert to the older naming schema, given the big ‘push’ across almost every distro over the last 5+ years towards the new style. I can kind of understand it, in the sense that the stock hardware setup of a RPi is extremely unlikely to have more than one ethernet or wifi interface, so ‘eth0’ and ‘wlan0’ are pretty safe names. But… it does seem short-sighted in that it seems to be borrowing trouble if someone adds a USB dongle for either an extra ethernet port, or an extra wireless radio (create an AP).
I guess the ‘why’ is neither here nor there… what I’m curious about is whether there is an easy way to change the system back to the (new) normal network interface naming convention. Any ideas?
