Wordpress | Update of UpdraftPlus plugin failing

[donalhunt]

Wordpress has been struggling to update the updraftplus plugin for a few days...

This is the error when manually updating the plugin (the chmod warning is repeated many times):

Update failed: Warning: chmod(): Operation not permitted in /var/www/www.openstreetmap.ie/public/wp-admin/includes/class-wp-filesystem-direct.php on line 173

...

{"success":false,"data":{"update":"plugin","slug":"updraftplus","oldVersion":"Version 1.16.63","newVersion":"","plugin":"updraftplus\/updraftplus.php","pluginName":"UpdraftPlus - Backup\/Restore","errorCode":"files_not_writable","errorMessage":"The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions."}}

fixed with the following ownership change:

# chown -R www-data:www-data ./wp-content/plugins/updraftplus/

Plugin is now updated to version 1.16.65

Donal, Just to point out that a specific plugin for backups is not required. I have been backing up and restoring wordpress for years with just a mysql dump and a tar of the web files.
