This error message is usually being displayed when the plugin is not activated and you try to update it.
In case it is, please try to reactivate it (deactiate and then immediately activate again), this refreshes the database and should solve this problem as well.
I'm unable to update the plugin. I click the blue "Install Now" button and I get the following:
Update Plugin
Update package not available.
Return to Plugins page
I'm also unable to update it via the plugins page. I'm having this problem on multiple sites.
Thanks.
