We are running Wordpress version 6.1.1. When we try to update one or more (we've tried to do it in several ways) plugins, Wordpress returns a -1 (see image below)

Wordpress returning -1 when trying to update plugins

The system is then stuck in maintenance mode. We can only get the system out of maintenance mode by deleting the .maintenance file via FTP. Plugins do not update.

It seems that several template plugins are causing these kind of issues (Astra Starter templates, Smart Templates, etc.) If you have one of these installed, try to deactivate them and then update all the plugins, including the template ones. Once updated, you can safely re-active such plugins. Hope it helps.
