You shouldn’t need to change permissions since wordpress is logging in as if you were logging in via FTP.
All you need to do is rename the folder upgrade to ‘upgrade2’ and then rerun the upgrade automatically link. WP will recreate the upgrade folder and proceed.

I had this issue with using the TweetThis plugin. Disable all your plugins and add one by one.
I was also able to fix this by using WP Supercache.
