Update to 6.8 failed

Hi, my update to 6.8 keeps failing and I’m not sure what to do. It says usually due to inconsistent file permissions but how do I change that? Can anyone help? I’m a rookie at this stuff.

Also, do I really need to update? I get daily emails about updating but my site seems to be working fine with the update.

Here is the error message I’m getting when I try to update:

Downloading update from https://downloads.wordpress.org/release/wordpress-6.8-no-content.zip…

The update cannot be installed because your site is unable to copy some files.
