Unable to changer fichier permissions on Ubuntu Bash for Windows 10

[ForumBot]

I was trying to use an ssh instance and I received l'erreur suivante, which is odd since J'ai essayé de change the permission using `chmod`, but that didn't seem to work as permissions were still `777`:

```
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: UNPROTECTED PRIVATE KEY FILE! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0777 for 'privkey.pem' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "privkey.pem": bad permissions
Permission denied (publickey).

```

J'ai ouvert `git bash` and was able to SSH into my instance with no problem, and permissions were not `777` aussi.

Si vous êtes referencing files in the Windows système de fichiers, they do not, par défaut, retain Linux permissions.
Cependant, there's a way to enable that. Edit or create (using `sudo`) `/etc/wsl.conf` and add the following:

```
[automount]
options = "metadata"

```

Shut down all WSL instances and restart an instance, and any `chmod` changes are now retained.
