Почему не подключается Bluetooth девайс?
Все предыдущие шаги из гайда были выполены. Т.е. пэиринг прошел удачно:
Собственно я не могу понять в чем проблема и что за ошибка:
> Failed to connect: org.bluez.Error.Failed
В гайде сказано, что при возникновении такой ошибки требуется убить демон pulseaudio (pulseaudio -k), но мне это решение не помогает и проблема остается не исправленой.

connect error: Software caused connection abort (103), что это может значить? Можно ли где-то посмотреть более подробный лог того, что происходит? Я посмотрел арч вики по bluetooth, но там ничего про логирование или эту ошибку не нашел.
P.S. Я уже ранее испытывал данную проблему, не помню как ее решил. Либо методом научного тыка, либо все само починилось, далее все хорошо подключалось до недавнего обновления системы. Ничего специфического не делал.

I’m having trouble connecting to my radio for audio output, it most certainly can connect when I use my Android phone, or my previous Windows 10 install. It even worked with Linux Mint 20, but Arch with Plasma 5 says «Resource temporarily unavaliable» if I try to connect from System Settings.

Thanks for reading. If you need any further info feel free to ask.

Ubuntu 20.04 Bluetooth «Connection to the device failed»
This is to my bluetooth headphone. 
Then I click on «Connect», and after a few seconds, I get this message: 
«Connection to the device failed» The strange thing is, this has worked previously. There might have been updates in between but I’m not exactly sure. Also, I was dual booting Windows before, and there Bluetooth with the same headphone works just fine. I recheck by booting in again to Windows, and it still works, but then booting back to Linux, and it does not work. This sounds related, because some people also report dual boots with Windows. However, the suggestion with reloading btusb (or maybe also btintel ) did not help. I had some previous issues with wifi + dual booting with Windows before. I did sth and it solved it, but I forgot what I was. I remember that to permanently get rid of this, I was supposed to disable the Windows «Fast Boot» feature. But there was another workaround to make it working. Related questions here or here, but I had found some other question/website with more information, but I don’t find it anymore. Anyway, I disabled the «Fast Boot» feature in Windows, and the wifi is working all the time. I did not had any issues anymore.

After a bit of digging I was able to sove this issue for myself which involved connecting a bluetooth audio device. For me it was specifically a JBL Charge4.
The solution was to install the pulseaudio Bluetooth module and restart it:
sudo apt install pulseaudio-module-bluetooth pulseaudio -k pulseaudio --start Then when I try to pair I no longer get the message and it works.
