Just installed Ubuntu on to my Raspberry Pi 4 (8GB). But I hate wires, so I want to connect my BT keyboard and mouse. However I get the [Please plug in dongle] message when I open by BT settings.

I have also tried updating the software and firmware as well as commands such as

sudo systemctl restart bluetooth service bluetooth restart

when I run

service bluetooth service

I get

     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)

I've also noticed that a log of the config files are empty? Is this normal? I only figured this out when I overclocked the CPU.

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.
