Error when launching nRF Connect for desktop on Linux.

[Chams]

I have recently installed nRF Connect for desktop V3.0.0 on my ubuntu machine and I installed the Bluetooth Low Energy App but it doesn't launch and I keep getting this error : 

   " Error while probing devices: Error occured when get serial numbers. Errorcode: CouldNotOpenDLL (0x7) Lowlevel error: JLINKARM_DLL_NOT_FOUND (ffffff9c) " and I can't seem to find this missing file. Also when I tried to download JLink from SEGGER website I went through all the steps to get to the download link of the .deb file but when the download finishes I get a .html file and not the .deb. I don't really get what's going on.

Please can anyone help me.

No I don't want to use any dongle I wish to advertise a custom ble service using nRF connect for desktop just like the mobile app but I don't get how to do that. Is it possible ??

No, you need to use Bluez,etc to control regular BT HW. nRF connect desktop will only work with the Softdevice stack. You could try noble if you comfortable programming with Javascript: https://github.com/noble/noble-device. There are also Python modules available.

Yes I'm trying to do it using Bluez and I will try out what you suggested. Tank you very much for helping me I really appreciate it.

we have installed the following debs

-JLink_Linux_V684a_x86_64.deb

-nRF-Command-Line-Tools_10_10_0_Linux-amd64.deb

After that my programmer(1.4.6 , nrfConnect 3.6.0) starts without any error and I managed to flash my Thingy91
