WordPress update failed to complete

I have a bunch of sites running on a Debian multi-site setup. Managing it is normally simple.

However, one day I activated automatic WordPress updates. Big mistake.

The next minor WordPress update failed miserably, due to lack of permissions, and all the sites carried the message:

An automated WordPress update has failed to complete - please attempt the update again now.

There was no way of getting rid of the message.

In the end, after much digging, I discovered that WP had set an option “auto_core_update_failed” on the sites. Removing that the message disappeared.

The issue is here on the WordPress Developer site.

The WordPress CLI command is your friend for these things.
