unable to upgrade wordpress: "Could not deactivate the 'wp-fail2ban' plugin."

Describe the bug

When trying to update from version 5.9.3~ynh2 to 6.1.1~ynh1 I get the error message: [Error] Upgrade failed.

Apparently it's because the plugin wp-fail2ban cannot be deactivated (it is already deactivated, since the redux one is already there and active).
