It seems that rtl8761b-fw.bin is a Bluetooth 5.0 driver that I had to manually install 6 months ago to get a cheap Amazon BT 5.0 dongle to work. I don’t know if I’ll still it yet, but I’m not sure how to fix. Any help appreciated.

It’s an AUR package most likely. Try updating with yay.

That is a tough one.

It is possible that firmware has been added to linux-firmware and you need to remove the AUR package before updating.

It is also possible that what is in linux-firmware won’t work.

Since it is only BT support, I would try removing the AUR package first and see if it works without it after rebooting.

So, there is an AUR package when I search yay:

yay 8761
2 aur/rtl8761usb-dkms 20201202-3 (+1 0.09) 
    Realtek bluetooth modules for RTL8761 usb based devices (DKMS)
1 aur/rtl8761usb 20201202-3 (+1 0.03) 
    Realtek bluetooth modules for RTL8761 usb based devices

but I installed it manually (don’t remember how though), through some modprobe-ing. :confused:

5

I don’t think so, it is owned by the package rtl8761b-fw

6

yay doesn’t report an “installed” package though.

I know I did it manually because no drivers were provided when I bought it, so I had to Google it forever and find it.

7

Like you said you probably just used modprobe to load the module.

8

That is because of how you are using it. That isn’t how you check for installed packages. Try:

yay -Qs 8761
9

You can save a copy of the file before you remove package if you want to.

I believe I used some steps in this (everything listed before 2021):

(1) https://bbs.archlinux.org/viewtopic.php?id=260125

and this:

(2) Readme file for “mpow_MPBH456AB_driver+for+Linux.tgz”
Readme.pdf (18.1 KB)

yay -Qs 8761 lists this:

yay -Qs 8761
local/rtl8761b-fw 20200816-1
    Realtek bluetooth firmware for RTL8761B based devices
11

That topic says this in the end:

there’s a package in the AUR for this chip - rtl8761b-fw

My guess is that package isn’t there anymore but was at the time.

y’all…

In ~October 2020, when I manually installed this driver, that Feb 2021 suggestion did not exist yet. So I could not have installed it via that method.

Regardless, I still need a way to fix my kernel, how should I continue? I don’t mind uninstalling that original package, but I don’t know how to do that.

14

I think you installed the firmware using a different method most likely?

15

Maybe? I had another kid since then so my dad brain is still scrambled

16

I’ll let @dalto give you advice to remove the file and update just so i don’t send you down a bad path. :laughing:

17

First, save a copy of the file, just in case. Then you simply remove the package. Like this:

cp /usr/lib/firmware/rtl_bt/rtl8761b_fw.bin ~/.
sudo pacman -R rtl8761b-fw
18

Does this copy it to / or what is it called?

19

That copies it to your home directory.

I was going to say that first but wasn’t sure if that’s where it went. If you were to say /home instead would that not work also?

Edit: Or i need user also
