Editar: Eu atualizei meus certificados de CA raiz do curl.haxx.se.
Quando eu tento curl -Iv https://yahoo.com , recebo um erro como unable to get local issuer certificate no resultado. No entanto, se eu tentar curl -Iv --cacert /etc/ssl/certs/ca-certificates.crt https://yahoo.com , obtenho um resultado sem nenhum erro.
Estranhamente curl -Iv https://google.com funciona corretamente. Mas curl -Iv https://deb.nodesource.com não.
Existe alguma chance de superar esse problema? (mudando a configuração de curvas etc.)

curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
O Becase curl não consegue verificar o certificado fornecido pelo servidor.
Existem duas maneiras de ignorar:
1.add -k opção que permite que o curl faça conexões inseguras, o que não verifica o certificado.
2.add root curl ca ( faça o download aqui ) para /etc/ssl/certs/nodesource-ca.crt
Ou, para mim, trabalhei simplesmente isso:
sudo apt-get install ca-certificates
