I'm running 19.10 (although this was also an issue on 18.04 before I upgraded) on an older Intel NUC. I am unable to see or access the wired settings for my connection (see attached image), nor is the OS able to access the internet for updates. For example, the Ubuntu Software app, when I go to Updates, it says I need to go online to check for updates. I have no problem actually getting online with a browser or whatever...I'm posting this from this machine...but updates in that app, as well as things like the Online Account settings, don't think I'm online.
Let me know if there's any other info you need to help me diagnose this problem. Thanks in advance for any help.
EDIT (further clarification) - the system software updater works fine, but the "app store style" software updater tells me to "Go online to check for updates".
Also, when I go to to the "power menu" and see the options for my user account, night light mode, and the network stuff, it says "Wired Unmanaged", but if I click on "Connect" under that, it doesn't do anything.
I'm also running a handful of docker images, just fyi, because I know that has it's own networking "situation" going on.
EDIT (more info) - running desktop version
