Sometimes I notice that I am unable to connect via SSL with
curl
andwget
to websites that have certificates that should be valid.One example might be
https://squareup.com/
which has a Verisign class 3 certificate - I assume a large banking-related site has a certificate that should be widely accepted.However when I try and run:
wget -O - https://squareup.com/ #grab the homepage and send it to stdout
I get the error:
Unable to establish SSL connection.
Does this mean my system's certs, perhaps one of the
cacert.pem
files, is out of date?I'm on Ubuntu 12.04.1.
Yes, I know I can use
no-check-certificate
but I'm more curious about why this is happening in the first place.How can I update certificates on my system to fix wget's error: "Unable to establish SSL connection."?
