wsl2 fail to change file permissions

I am working on wsl2 of win10:

PS C:\Users\Gaowei> wsl -l -v
  NAME            STATE           VERSION
* Ubuntu-20.04    Running         2

After entering wsl, I make a file of test.md:

➜  ~ ls -l test.md
-rwxrwxrwx 1 gaowei gaowei 0 Aug 25 17:17 test.md

then try to change its permissions:

➜  ~ chmod 755 test.md
➜  ~ ls -l test.md
-rwxrwxrwx 1 gaowei gaowei 0 Aug 25 17:17 test.md
➜  ~ sudo chmod 755 test.md
➜  ~ ls -l test.md
-rwxrwxrwx 1 gaowei gaowei 0 Aug 25 17:17 test.md

Unfortunately, it turn out to be stay unchanged.

My machine info:

The problem was solved by creating /etc/wsl.conf file and configuring it as:

# Enable extra metadata options by default
[automount]
enabled = true
root = /mnt/
options = "metadata,umask=22,fmask=11"
mountFsTab = false
# Enable DNS – even though these are turned on by default, we'll specify here just to be explicit.
[network]
generateHosts = true
generateResolvConf = true

Reference : wsl.conf
