No ethernet detected

Problem Description
I tried to install freedombox on a raspberry 3 + but when I start the raspberry first line is: Net: ethernet not detected, then a bunch more of lines at black screen. I’ve tried installing raspbian on the same sd and ethernet works.

What can I do? Thanks!

No problem, just go into network settings and click on the wired network, there you can edit. Choose your network card in the options and the rest of the options in automatic. It should work
