I just upgraded my computer form Ubuntu 18.04 to Ubuntu 20.04 using the terminal. Everything went fine (except for some issues with the video card embedded in the motherboard but I was expecting this and I should have fixed it) but now I cannot turn on the bluetooth switch. I have a bluetooth dongle (Qualcomm Atheros Communications AR3011 Bluetooth, according to lsusb) but I did not menage to turn it on. If I run sudo modprobe btusb I get an erro message saying:

modprobe: FATAL: Module btusb not found in directory /lib/modules/5.4.0-1053-gke

I have upgraded (both with update and dist-update) but all package are up to date.

The output of service bluetooth status is:

 bluetooth.service - Bluetooth service
     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
     Active: inactive (dead)
       Docs: man:bluetoothd(8)

The output of lsusb is:

Hey! Did you manage to find a fix?

I changed the kernel to the generic version using uktools (https://github.com/usbkey9/uktools) and then it worked again!

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.
