Did Bluetooth work on the machine before the upgrade? What Bluetooth device or procedure are you trying to use? What error message are you getting?

A search of the error in your post "Failed usb_autopm_get_interface with -16" shows this is most likely a kernel error. What kernel are you using?

Thank you @David for your reply. Before upgrading to 22.04 I was using bluetooth. There was no problem.Now I am trying to use the build in bluetooth service. The Kernel I am using is Linux 5.14.0-1052-oem.

Ubuntu 22.04 shipped with 5.15 how did you get downgraded?

Dori

I have no idea about the kernel version. I have upgraded to 22.04 from 20.04 with software updater.

In a terminal run the uname -a command just to be sure.

Dori

10/16/23, 2:16 PM

The output of uname-a is `Linux dori-Inspiron-3505 5.14.0-1052-oem #59-Ubuntu SMP Fri Sep 9 09:37:59 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux`

It is a custom kernel from Dell?

Dori

10/16/23, 2:22 PM

Yes, I guess it is.

David

10/16/23, 2:25 PM

See if they have a newer kernel.

Dori

Thank you @David. The problem was with kernel.I have installed a fresh version of Ubuntu 22.04 with kernel 5.15 and now my bluetooth is working.

David

Great glade it is fixed. Mind if I make that an answer and you can accept it?

If you have done an upgrade from Ubuntu 20.04 to 22.04 and are using a Dell OEM kernel you may still be using an OEM kernel after the upgrade. If your Ubuntu 22.04 is using the 5.14.0-1052-oem kernel your Bluetooth will most likely not work. A fresh install of Ubuntu 22.04 will give you the default kernel, 5.15 kernel and your Bluetooth will work. To verify what kernel you are using in the terminal you can use the uname -a command.

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.
