Whenever I update anything on my local WordPress development site, whether it be plugins, themes, or the WP 3.7.1 update, I get this error message:
Unpacking the updateâ¦
The package could not be installed.: PCLZIP_ERR_BAD_FORMAT (-10) :
Unable to find End of Central Dir Record signatureInstallation Failed
I’m using WampServer 2.4, with Apache 2.0.63, PHP 5.2.11, and MySQL 5.0.88.
I had same issue today on my new server.
After a while i realize that zip/unzip is not active in my apache/php . When i recompile my apache with zip extension , problem solved.
