I was trying to install artiq on WSL Linux subsystem following the instruction in ARTIQ Manual, and encountered the following problem: after I created the flake.nix file in an empty dictionary as instructed in the manual, I launch the command nix shell in the same dictionary. The terminal asks for confirmation of the configuration setting as in the manual, but after I confirm all setting, the installation failed with the warning:
warning: creating lock file '/home/zhangzj/opt/artiq/flake.lock'
error: opening file '/home/zhangzj/opt/artiq/flake.lock': Permission denied
I also tried using the command nix shell --accept-flake-config --show-trace to trust all configuration setting and demonstrate the detailed error, and I always get the following error:
`warning: creating lock file '/home/zhangzj/opt/artiq/flake.lock'
error:
… while updating the lock file of flake 'path:/home/zhangzj/opt/artiq?lastModified=1679039554&narHash=sha256-zWoisYlIJTZ5iqPZqCc36%2fmfcbbRcr1rwPxbeXGp+CU='

   error: opening file '/home/zhangzj/opt/artiq/flake.lock': Permission denied`

However, there is no flake.lock file created. How should I tackle this problem?

Try changing the permissions on the relevant paths.

How to do so? I am not familiar with Linux commands, and from the file manager of Windows, the path where flake.nix is located is set as READ ONLY, and changing it from the "Property" manual seems useless.

Try with chmod from the WSL prompt instead.
