I am using Ubuntu in my VirtualBox on my Windows 10 Laptop. I set it up ages ago and never really had any issues or if I did, I found a way to solve it. But just now I started my virtual machine, did some stuff and then decided to run sudo apt-get update and sudo apt-get upgrade. And now I can't get my virtual Ubuntu (18.04.06 LTS) connected to the internet anymore. I am using the standard VirtualBox network settings, meaning I have one network adapter, attached to NAT. Never changed anything about that. Also, I am using a wired connection.
To be honest, I don't really know where to start at, like what commands can I run to get some output that helps me to identify the problem? All I see is the network symbol in the upper right corner with a question mark, but that's about it.... What can I do to get to the bottom of this? Any help appreciated since I am a complete beginner with Linux/Ubuntu....
Thanks in advance, marvin
