I have a problem with Bluetooth on my PC; I put Ubuntu on my Laptop. I have never had a problem but recently, the Bluetooth no longer works. It has always worked very well but overnight the Bluetooth no longer works — it shows me "No Bluetooth Found" "Plug a dongle to use Bluetooth". I don't know what to do. I have recently formatted my PC and completely reinstalled Linux. I'm on Ubuntu 22.04.2 LTS

this is the results for lsusb:

Welcome to Askubuntu. Please provide the type of Bluetooth and/or make and model you are using. If you are using a USB Bluetooth, you can find information using the `lsusb` command. Most importantly here, is the alphanumeric code for the USB device which is something like abcd:1234 or something similar like a1b2:c3d4. If not a USB device, then use the `lspci` command to list all your devices and then look for the Bluetooth device in the results. Also, please provide the version of Ubuntu. Thanks.

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.
