Support » Installing WordPress » Update to V6.4.1 failure

  • team118



    I am helping to take over updating our website which has not been changed or upgraded in many years. I do not know the current WordPress version, but there are numerous links to update to V6.4.1

    When I attempt to do so, I receive an error message:


    Update WordPress

    Downloading update from…

    The authenticity of could not be verified as no signature was found.

    Unpacking the update…
    Notice: fwrite(): write of 8192 bytes failed with errno=28 No space left on device in E:\web\catalina380\htdocs\wp-admin\includes\class-wp-filesystem-direct.php on line 76

    Could not copy file.: wordpress/wp-includes/css/editor.min.css

    Installation failed.


    I cannot tell if this is a server issue that our website is hosted on or not. However, many of the newer mods, plug-ins and page builders are incompatible with our current version.

    Our current website is frankly a mess and I am hoping I can fix it rather than start all over….

    Thanks for any thoughts or guidance

    It’s a server issue, but probably not quite what you think.

    The error message says “No space left on device” which means that the ZIP file for the new WordPress version either can’t be saved, or can’t be expanded because there’s not enough disk space available to do that.

    The first thing to do is log into your hosting account control panel – note that this is NOT your WordPress site, but the main account with your hosting company. In there you should be able to see how much space you have left for your site. It won’t be much.

    If you have access to a file manager in your hosting account area, or you can use FTP to view the file system, you can look for any files that don’t need to be there and delete those. Things like log files and error logs can be safely deleted, but unless you know what you’re doing I wouldn’t go too crazy with this!

    The easiest thing to do is talk to your hosting company and upgrade your hosting account to allow more disk space. That will let you do what you need, and expand your site as it’s needed.
