22.04 Says I'm not connected to the internet but I am

I just setup a new machine with Ubuntu 22.04 Server. I am connected to the internet as I can browse and download files with no issues. When I go to settings to add an online account, it tells me that I am not connected to the internet. The network settings only show VPN settings and not Ethernet (currenly plugged in). The network dropdown on the top bar says Unmanaged and the options are Connect and Wired Settings. Neither one shows on the Network Settings menu.

I can't find any good help to fix the issue. Any thoughts?

Any help is appreciated.

Edit to add… I have a gui installed for easier management for me.

If it is a server, how are you "going to settings"? Did you install a graphical desktop? Servers typically don't have `network-manager` installed which the graphical desktops typically use.

Yes. I installed a desktop. I like all the command line stuff but I still feel more comfortable with a gui interface on things I don't know how to do via command line.

That kind of crucial information should go in your question.

Are you using a VPN?

No vpn. But strangely enough, that is the only option on the networking tab.

If you wish for your networking to be controlled by the graphical interface; that is, Network Manager, please amend your netplan yaml file. First, back up the current file:

sudo mv /etc/netplan/*.yaml  /etc/netplan/*.bak

Write a new file:

sudo nano /etc/netplan/01-network-manager-all.yaml

Write the following:

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

Netplan is very specific about spacing, indentation, etc., so proofread carefully twice. Save (Ctrl+o followed by Enter) and exit (Ctrl+x) the text editor.

Follow with:

sudo netplan generate
sudo netplan apply
sudo service NetworkManager restart

You should be all set.

Thanks. This seems to have fixed it. I have the network controls showing up now.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
