permissions errors when updating to 2.5.39

When trying to update to 2.5.39, I get the following error pasted below, and the update fails.

Otherwise, the sites (and the plugin) seem to be working fine.

An error occurred while updating All-in-One Event Calendar by Time.ly: The update cannot be installed because we will be unable to copy some files.
