Answer 1

Both Amades and Chaos answers are correct. But it only works for local drives not for mapped network drives. Z: is one of my network drives. Same operation on /mnt/c/Users/xxx/ works fine.

$sudo mount -t drvfs Z: /mnt/z -o metadata
$touch test
$chmod +w test
 chmod: changing permissions of 'test': Operation not permitted

This is a known issue, see drvfs: metadata (chmod\chown) possible for mounted SMB drives?

Answer 2

There was an update to WSL recently (source), which lets you change permissions to files (Insider Build 17063).

All you have to do is to run:

sudo umount /mnt/c
sudo mount -t drvfs C: /mnt/c -o metadata

Answer 3

Amade's answer is correct, but please note, the cmd only take effect in session scope. If you exit current bash, you'll lose your setting.

To fix this, you need to edit /etc/wsl.conf. and put below config in.

[automount]
enabled = true
options = "metadata"
