Problema installazione Symfony

[fermat]

ciao ragazzi!

su debian 10 sto avendo dei problemi con symfony.
gia con il binario:

$ wget https://get.symfony.com/cli/installer -O - | bash
--2020-05-15 12:44:07--  https://get.symfony.com/cli/installer
Risoluzione di get.symfony.com (get.symfony.com)... 99.86.163.40, 99.86.163.126, 99.86.163.18, ...
Connessione a get.symfony.com (get.symfony.com)|99.86.163.40|:443... connesso.
ERRORE: il certificato di "get.symfony.com" non è fidato.
ERRORE: il certificato di "get.symfony.com" non ha un emittente conosciuto.

poco male, l'ho scaricato manualmente.
però:

$ ./symfony new test_sym --full

composer è installato e funzionante:

$ composer -V
Composer 1.8.4 2019-02-11 10:52:10
