Hi @Abdelkrim Boujraf, I think I see the issue here. I believe at this time, you need to have an IBM internal network connection to complete the installation on WSL. That would be why the connection to the ibm.com domain fails. You are a business partner, correct?
Alternatively, you can try installing at least version 13 on Linux instead of Windows but no guarantees that this will resolve the issue. Sorry, I am not an expert but have seen some tips and tricks internally 😊
