Nah we will get past it.
let me see this please:

less /var/lib/dkms/btusb/4.0/source/dkms.conf

[drumone]

MAKE="'make' all KVER=${kernelver}"
CLEAN="make clean"
BUILT_MODULE_NAME=btusb
BUILT_MODULE_NAME[1]=ath3k
DEST_MODULE_NAME="btusb"
DEST_MODULE_NAME[1]="ath3k"
DEST_MODULE_LOCATION="/updates"
DEST_MODULE_LOCATION[1]="/updates"
PACKAGE_NAME=btusb
PACKAGE_VERSION=4.0
REMAKE_INITRD=yes
AUTOINSTALL=yes

[#&thj^%]

Here it is>>"AUTOINSTALL=yes"
Before I start swinging any hammers here, first give this a try:

sudo nano /var/lib/dkms/btusb/4.0/source/dkms.conf

Change that line I show to:

AUTOINSTALL=no

Save and exit, now upgrade with:

sudo apt install -f

Fingers Crossed

[drumone]

Ummm.... nope. I even double checked the file to make sure it was changed properly.

drumone@Linux-Desktop-2021:~$ sudo apt install -f

[#&thj^%]

please show me this:

apt policy btusb

if nothing try this:

apt search btusb

If there is still nothing shown,,,,Hammer Time...LOL

sudo rm -rf /var/lib/dkms/btusb/4.0/source/dkms.conf

[drumone]

Well, in keeping with the music theme.... Sledge Hammer! Rebooting now and hoping it worked.

[drumone]

Aaaaaaaaaand... Success!! Thank you @1fallen!!! I greatly appreciate your time and effort to help me with this.

[#&thj^%]

Go Team!
lets not forget to clean up a bit:

sudo rm -f /etc/apt/sources.list.d.bk

You now seem to have a good source list so the back-up can be trashed

And you can if(?) you want re-install bluetooth again
