Unable to install SDK via VS Code

[akshaybabloo]

I have installed nRF connect 2025.9.732 on my VS code Version: 1.103.2 on Ubuntu 22.04.

I am able to install the toolchains successful but I am getting this weird error message

I have west installed globally via pip, but I do NOT have ZEPHYR os installed in ~/zephyrproject.

I am not sure what that error is, do I have to go to /home/akshay/ncs/v3.1.0 and type west update?

I have an almost identical problem. I updated toolchain (using 'Manage toolchain') and SDK (using 'Manage SDKs'), both from a happily working v3.0.2. I'm running Windows 10 on a PC.

Installs seemed to go OK but building my projects with these updates fail, exactly as per this thread. I tried suggested solution 'west update' and also 'west -v update'. Creating a new project with these updated tools also fails.

Note that I am new to Zephyr and have no idea what these commands do. But they seemed to run OK. But underlying problem persists.

Just a guess - Could it be a permissions thing ? Do I have to run VS Code as administrator to do these updates ?

I also have pretty much the same issue for macOS 15.6

Hi,

So far we are unable to reproduce this issue. Thank you for reporting this. 

Could you try to remove the previous west installation and try again from a clean state?

Maybe the west main utility is the issue here.

I am in the process of doing this now, although I don't have the knowledge or skills to remove the 'west installation', as I have only a very vague idea of what that is. Instead I am removing all things Nordic from my PC and doing a complete re-install based on Lesson 1 in the Developer Academy course. This will likely take a number of hours.
