Thanks. I see you're one of the WP Rocket developers.

I had problems updating on my local install of WordPress because of this licence check.

First I had queried the production server for the update URL:

wp plugin list --update=available --fields=update_package --format=csv | tail -n +2 | grep wp-rocket

Then locally, where the plugin was disabled:

WP_HOME="https://www.mydomain.com" wp plugin install --force https://wp-rocket.me/12345678/wp-rocket_3.14.2.1.zip

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

And the downloaded zip contained:

BAD_UA_XR: WordPress/6.2.2; https://www.mydomain.com & not set%

I see the header is updated in: \WP_Rocket_Requirements_Check::add_own_ua()

to be: WordPress/6.2.2; https://www.mydomain.com;WP-Rocket|3.13.1|12345678|[email protected]|https://www.mydomain.com|8.1;

So this worked to install the plugin locally:

WP_HOME="https://www.mydomain.com;WP-Rocket|3.13.1|12345678|[email protected]|https://www.mydomain.com|8.1;" wp plugin install --force https://wp-rocket.me/98426592/wp-rocket_3.14.2.1.zip
