Issue with Ubuntu admin tools that do not detect wifi properly

my flag
Fred L.

I've done a fresh and clean install of Ubuntu Server 20.04 LTS on a NUC 10i7 Network connection is done thru wifi, and this message is written from Firefox installed on this server, so it is working fine. After reboot and run:

sudo apt update && sudo apt upgrade && sudo apt-get install tasksel -y

I installed ubuntu desktop and ubuntu minimal desktop using: sudo tasksel When I try to configure thru parameter GUI: Wifi,and livepatch configuration failed: notice: Internet connection is missing... But I was able to sudo ua attach with the right key, and this post is written thru this server.

so I've configured my wifi connection with by CLI using netplan.

What's wrong?

So I've decided to do another fresh and clean install using Ubuntu 20.04 Desktop, and everything is working perfectly! Going back to Ubuntu 20.04 Server, and issue is back!

some capture/logs:

Seems like normal and expected behavior. Ubuntu Desktop includes more kernel modules for wireless chipsets than Ubuntu Server includes. In the past, wireless has not been reliable enough for regular server use. Simply install the appropriate kernel module for your wireless chipset. Use `sudo lshw` to find your chipset model. If you need help figuring out which module to add, or need help reading the `lshw` output, add the lshw output to your Question above.

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.
