    Try MANUALLY updating:

    – Plugins:
    https://codex.wordpress.org/Managing_Plugins#Manual_Plugin_Installation
    https://codex.wordpress.org/Using_Themes#Adding_New_Themes_Manually_.28FTP.29

    – Themes:
    https://codex.wordpress.org/Using_Themes#Adding_New_Themes_Manually_.28FTP.29

    – WP:
    Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old wp-admin and wp-includes folders and files on your server before uploading the new ones. Please read the Manual Update directions first.

    All well and good suggesting a manual update *but* why is this happening? One assumes that there is a checksum stored somewhere for the download (separate to the download) but after downloading, the checksum is incorrect calculated for the zip file doesn’t match? Does somebody need to update the download system with the right checksum?

    Also, what checksum algorithm is it using?

    I’m getting the same error with v4.8.1:

    Update WordPress
    Downloading update from https://downloads.wordpress.org/release/en_GB/wordpress-4.8.1.zip…
    Download failed.: The checksum of the file (db3941fd244e09bcc5eaf6684715ae16) does not match the expected checksum value (1ea35c589fd15b2332f43ddf171695d8).

    Interesting, when I generate the MD5 checksum for the manually downloaded zip file, it’s getting the expected value so this sounds like the download is not working correctly.

    Side note to @robnicholson,

    Please do not jump into other topics.

    If the troubleshooting already posted made no difference for you, then, as per the Forum Welcome, please post your own topic.

    Err, I don’t understand your comment t-p. I’ve got exactly the same error so why would I post another topic on the same problem??

    Very simple, as per the Forum Welcome, please post your own topic 🙂

    *Without* changing the subject.

    Downloading update from https://downloads.wordpress.org/release/wordpress-4.8.1-partial-0.zip…

    Download failed.: The checksum of the file (d41d8cd98f00b204e9800998ecf8427e) does not match the expected checksum value (93f5b9e6f0e24e245899165c6701f222).

    Installation Failed

    I have the exact same issue: now it’s all well and good saying do a manual install, and reading the instructions gives me the goosebumps, and yes! – At some point when I have half a day to spare, I’ll give it a go, but the question remains: why did the installation fail originally?

    Rider: I know you work hard to provide this platform, and it’s all free of charge, and I know you are proud of what you do here, but when this happens: you chaps get really uptight, as in the above response to check-sums.

    – Something wrong happened here, and no one is pointing fingers, but a manual update of your site isn’t to be taken lightly. Perhaps one of you wizards could look into it at sometime, and (honestly:) tell us what happened here.

    BTW – My other two sites updated without a hitch, but the one with the subdomain didn’t. This extra information (off topic), may help you track down the issue that caused my, robnicholson: and mhardin1369 problems.

    Many thanks for reading, Jessica.
