    Exclamation Ethernet Not Working After 18.04.02 Update

    When I reinstalled Ubuntu Budgie 18.04.2, the wired connection was working as I downloaded software updates during the installation. However, the wired connection did not connect. Here's my log when I executed the command

    It seems like I have fixed the issue by downloading Ukuu and upgrading my kernel to the latest version. Now it works like a charm.
