Initial WiFi Setup Issue in U20.04 Server

I just installed Ubuntu Server 20.04 on an old HP PC (AMD Phenom II quad-core with 8GB RAM and large hdd). After realizing I needed wired internet to configure WLAN, I dutifully broke out the obligatory, decade-old, unused ethernet cable and got to work.

I did some research here and elsewhere, and made adjustments to netplan using my .yaml. 500 indentation issues later, I finally got sudo netplan apply to shut up after hitting enter.

“$ ip a” showed address for ethernet, but WLAN returns “<NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000 link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff” where “xx:…” is a bunch of random numbers/letters and “ff:…” is actually “ff:…”.

No wireless connectivity. I have not tried to connect wirelessly after reboot yet. I believe my system time/date is correct.

[EDIT]: Adding info almost immediately after posting - I did install wpasupplicant. Also, I don’t know how to do the whole box with code thing to show you the edits I made to *.yaml, but I spent a lot of time trying to learn how to do it correctly on netplan.io, which is really not that helpful for what I was attempting. Also - I just tried to connect wirelessly after reboot and no luck.

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.
