I just updated my laptop from 17.10 to 18.04 LTS. However, only my wifi connection still works, while the lan connection is not able to work anymore. I saw that others ran into similar issues after updating their system, however, nothing worked for me. Maybe someone has an idea. ifconfig gives me this output:

My /etc/network/interfaces
looks like this:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
Any help is appreciated. Thanks, Daniel
