OpenSSL: certificate signature failure error
- by e-t172
I'm trying to wget La Banque Postale's website.
$ wget https://www.labanquepostale.fr/

ERROR: cannot verify www.labanquepostale.fr's certificate, issued by `/C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=Terms of use at https://www.verisign.com/rpa (c)06/CN=VeriSign Class 3 Extended Validation SSL SGC CA':
certificate signature failure
To connect to www.labanquepostale.fr insecurely, use `--no-check-certificate'.
Unable to establish SSL connection.
I'm using Debian Sid. On another machine which is running Debian Sid with same software versions the command works perfectly. ca-certificates is installed on both machines (I tried removing it and reinstalling it in case a certificate got corrupted somehow, no luck).
Opening https://www.labanquepostale.fr/ in Iceweasel on the same machine works perfectly.

Any idea why I get certificate signature failure? As if this wasn't strange enough, copy-pasting the "server certificate" mentionned in the output and running openssl verify on it returns OK...
