Error Updating core WordPress (3.8) and plugins - PCLZIP_ERR_BAD_FORMAT (-10) (6 posts)

    I'm having a problem updating my sites through the Admin panel. I receive the following errors when updating both core and plugins. My hosting provider has looked into it. In an attempt to solve it, they increased the PHP timeout values and server space. However, I had plenty of server space available. None of this worked. I have updated a few of the sites using ftp without any problem. However, I have 15+ sites that need to be updated. I'd like to find out why this is causing problems.

    Initially, WordPress provided me with the following error:

    ------------Start----------------

    The package could not be installed.: PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

    -------------End-------------------

    Now, WordPress has added in the following errors:

    ------------Start----------------

    This was the response from my hosting company after working on it for the past 36 hours ...

    This issue with updates for plugins failing on wordpress seems to be popping up a lot more in recent days from what I have seen. So far it looks to only affect modern installs 3.7.1 or newer. We're still looking into whether there is a server side issue, but since I've noticed this on other servers as well, I've been wondering if there is a bit of an issue with wordpress itself. We are however still looking to see if we can come up with a workaround to get this running.

    It is a server configuration error related to an unresolved dns issue.

    If you google this, WordPress could not establish a secure connection to WordPress.org you will see this is resolved at the host level.

    Hi kmessinger,

    Thanks for your reply. The hosting company has already tried increasing the available disk space, as well as increasing PHP timeout values. These seem to be to two most common solutions. However, they didn't work. Do you have any suggestions that I can pass along to them?

    Thanks!

    Hi Pali,

    After going back and forth with my hosting company, looking at it from every possible angle, we determined that it was a problem with WordPress.org's servers. Very frustrating, esp when people on the forums here will assure you it has nothing to do with WP's servers. I politely disagree.

    You can manually update your site. However, if you have many sites, you might just want to wait a few hours, or a day, to run your updates.

    Good luck.
