Fix the “The package could not be installed. PCLZIP_ERR_BAD_FORMAT” WordPress Error

This is pretty straightforward, you’ll see this error when updating or installing a plugin.

[enlighter linenumbers=”true”]The package could not be installed. PCLZIP_ERR_BAD_FORMAT[/enlighter]

Basically the file WordPress is trying to download is either corrupt or you don’t have the PHP curl module installed. So simply install it, for Ubuntu this is:

[enlighter linenumbers=”true”]apt-get install php-curl[/enlighter]

or

[enlighter linenumbers=”true”]apt-get install php7.3-curl[/enlighter]
