LUBUNTU 24.04 LTS, LXqt

Whenever I connect my Samsung phone via bluetoth, it connects and then a second later it disconnects.

I sometimes have an error message Connection failed: br-connection unknown

I read up but I’m unsure what to do next.

Any suggestions?
Thanks!

Which kernel stack are you using?? the install Lubuntu 24.04 (or prior release install media if you release-upgraded to 24.04) install media will determine this. ie. what do you get from uname -r ?

Lubuntu 24.04 LTS being an LTS release has kernel stack options, with Lubuntu your default is set by downloaded & used install media; 2 ISOs using GA & 2 using HWE kernel stacks having been released thus far.

on my Lubuntu system here if I ask I’ll get

guiverc@d7050-next:~/snap$   uname -r
6.18.0-8-generic

where it’s the 6.18 I’m interested in (24.04 won’t give that value though)

( Kernel stack impacts the kernel modules being used; the common name for kernel modules is ‘drivers’ )

@basx Welcome to Ubuntu Discourse :slight_smile:

I edited your title because long titles like the one you had do not help the community to help you.

Please use descriptive titles with concise information.

Thanks

When it disconnects, open a terminal and run:
dmesg | tail
what is the output?

Hi guiverc,

Happy new year!

This is the output from uname -r:
6.14.0-37-generic

Actionparsnip,

Happy new year.

When I type dmesg | tail. I get an errir message about operation not allowed.

So I’m unsure what I’m doing wrong.

Can you paste the exact message, please

Try sudo dmesg|tail Is the phone also paired to Windows on the same computer? Or are you using a USB dongle on multiple computers?

I have 2 computers. The phone is paired with the Windows and I don’t have any problem. The other is the LUBUNTU. Right now I’m on the Windows., I did run sudo dmesg|tail and I got an error message about it being an illegal action. I’ll have to run it again and give you the exact quote.
