Plugin Updates show as Failed – could not be verified as no signature was found

  • Hi

    I have had a problem for a little while now that all plugin updates show as failed due to a signature problem, but they do actually succeed. This shows up both on my test site and my live site:

    Update Failed: {"success":true,"data":{"update":"plugin","slug":"ewww-image-optimizer","oldVersion":"Version 4.8.1","newVersion":"Version 4.9.2","plugin":"ewww-image-optimizer\/ewww-image-optimizer.php","pluginName":"EWWW Image Optimizer","debug":["Enabling Maintenance mode…","Downloading update from https:\/\/downloads.www.remarpro.com\/plugin\/ewww-image-optimizer.4.9.2.zip…","The authenticity of ewww-image-optimizer.4.9.2.zip could not be verified as no signature was found.","Unpacking the update…","Installing the latest version…","Removing the old version of the plugin…","Plugin updated successfully.","Disabling Maintenance mode…"]}}

    Update Failed: {"success":true,"data":{"update":"plugin","slug":"jetpack","oldVersion":"Version 7.6","newVersion":"Version 7.7.1","plugin":"jetpack\/jetpack.php","pluginName":"Jetpack by WordPress.com","debug":["Enabling Maintenance mode…","Downloading update from https:\/\/downloads.www.remarpro.com\/plugin\/jetpack.7.7.1.zip…","The authenticity of jetpack.7.7.1.zip could not be verified as no signature was found.","Unpacking the update…","Installing the latest version…","Removing the old version of the plugin…","Plugin updated successfully.","Disabling Maintenance mode…"]}}

    etc.

    Any pointers appreciated.

    Thanks
    Kevin

  • Just a guess but I’d probably disable that ‘WordPress File Monitor’ and try the update again if it still shows in my update available page.

    That plugin looks to be possibly abandoned or orphaned.

    If that doesn’t work then I’d disable all the plugins and try again as needed.

    Thanks,

    Without doing any disabling, the error has now changed, not getting the checksum issues anymore:

    Update Failed: {“success”:true,”data”:{“update”:”plugin”,”slug”:”wp-all-export”,”oldVersion”:”Version 1.2.4″,”newVersion”:”Version 1.2.5″,”plugin”:”wp-all-export\/wp-all-export.php”,”pluginName”:”WP All Export”}}

    but disabling WordPress File monitor didn’t solve it.

    Interestingly, I take an exact copy of the site (database dump, rsync, and db restore) onto a different host and I don’t get the issue – so looks more related to the host of the wp-config file rather than wordpress directly.
