Debug not working in Visual Studio Code

Question

I'm currently setting up an environment in Visual Studio Code because the roadmap suggests going there. 
 I have experience with Segger and Nordic Segger and with Zephyr. 
 I have installed NCS 2.0.0 and Visual Studio Code 1.70.0. It's hard to find a complete guide how to setup the environment. I'm using: - Ubuntu 20.04 LTS. - NCS 2.0.0 - NRF connect for desktop 3.11.1 - Visual Studio Code 1.70.0 - Toolchain Manager v1.1.3 - nrfutil version 5.2.0 - Zephyr SDK 0.14.2 
 I have used: https://academy.nordicsemi.com/topic/exercise-1-1/ https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html https://www.zephyrproject.org/zephyr-developer-summit-getting-started-with-zephyr-rtos-videos/ I noticed that there are differences in configuration. What I also notice is that a lot of things change all the time. VScode plugins getting deprecated. Environment variables no longer needed to be set. This is one of the reasons I make a new post. I also found: RE: Building/Debugging with Zephyr SDK Toolchain in nRF Connect VS Code (Linux) 
 But unfortunately it did not work for me. It also does not have all the information I need. Like where is settings.json located? Do I need to create it? I have no experience at all in Visual Studio Code. But I managed to install it, configure it and make the flash button work. I managed to get blinky working on the Nordic DK board. 
 Debug button does not work. I get the following error message: GDB executable "arm-zephyr-eabi-gdb" was not found. Please configure "cortex-debug.armToolchainPath" or "cortex-debug.gdbPath" correctly. 
 Then I have to choose between "cancel" and "open 'launch.json'". launch.json is not the same as settings.json. When I look at the previous post, I changed launch.json into: 
 
 { 
 // Use IntelliSense to learn about possible attributes. 
 // Hover to view descriptions of existing attributes. 
 // For more information, visit: go.microsoft.com/.../ 
 "version" : "0.2.0" , 
 "configurations" : [ 
 { 
 "type" : "nrf-connect" , 
 "request" : "launch" , 
 "name" : "Launch nRF Connect application" , 
 "config" : "" 
 } 
 
 ], 
 "cortex-debug.JLinkGDBServerPath" : "/opt/SEGGER/JLink/JLinkGDBServerCLExe" , 
 "cortex-debug.armToolchainPrefix" : "arm-zephyr-eabi" , 
 "cortex-debug.armToolchainPath" : "~/zephyr-sdk-0.14.2/arm-zephyr-eabi/bin" 
 } 
 
 But that did not work. 
 I also tried creating .vscode/settings.json with the following contents: 
 
 { 
 "cortex-debug.JLinkGDBServerPath" : "/opt/SEGGER/JLink/JLinkGDBServerCLExe" , 
 "cortex-debug.armToolchainPrefix" : "arm-zephyr-eabi" , 
 "cortex-debug.armToolchainPath" : "~/zephyr-sdk-0.14.2/arm-zephyr-eabi/bin" 
 } 
 
 But that also did not work. 
 The previous post also suggested to set the environment variable GNUARMEMB_TOOLCHAIN_PATH in .bashrc 
 export GNUARMEMB_TOOLCHAIN_PATH=/home/ephimee/ncs_v2.0.0/v2.0.0/zephyr/cmake/toolchain/gnuarmemb 
 But this also did not work. 
 I also tried opening VScode via Toolchain manager and without Toolchain manager in all scenarios. That did not make a difference either. What I did notice is that sometimes GNUARMEMB_TOOLCHAIN_PATH is set to zephyr and sometimes set to gnuarmemb. If I search on the internet there's no real answer where it has to be set to because both seem to work for some users? 
 I hope there are more suggestions?

This is not related to the problem. Anyway I spent some extra time and found why debug is not working: 
 ephimee said: "cortex-debug.armToolchainPath" : "~/zephyr-sdk-0.14.2/arm-zephyr-eabi/bin" 
 The ~ has to be replaced with the home directory of the user. In my case /home/ephimee 
 After I changed that, the debugger is working.
