I had a problem when I was going to configure roundcube webmail, where I had problems with GuzzleHttp\Client not loading (aka NOT OK) which prevented me from going to the next step
One way that I have done is try to install the library with the command "apt-get install php-guzzlehttp", but the package cannot be located. then I tried using composer to install the library, but the result I got is still the same.
my hope is that GuzzleHttp\Client can be loaded enter image description here
