Yeah, take a look at the makefile for wget and you can get an idea of how
complicated these kinds of general use programs are. you can make a
relatively simple http client in code, but trying to get it to handle all
the corner cases of the web, it's just easier to depend on something that
already does all the heavy lifting. For scripting, it's usually either
wget or curl. Full languages will tend to have their own http libs and
don't have to reach outside, though they will tend to depend on SSL/TLS
from openssl or gnu_tls on the OS to avoid having the implement that whole
stack in native code. Tend, not required. There is a native ssl
implementation in java for example.
Interesting about wget2. The distros I tend to use are so ancient I wasn't
aware it had been released. Finally support for some of the more modern
http options, which has always been a weakness of wget. Thanks for that!
Regarding the certificate trust issue, if you want to continue poking,
check to see if you have
/etc/ssl/certs/USERTrust_RSA_Certification_Authority.pem
check to see if that's in /etc/ssl/certs/ca-certificates.crt
If it is, try wget with --ca-certificate or --ca-directory options and see
if that helps.
Based on the error, ERROR: cannot verify
www.gutenberg.org's
<
http://www.gutenberg.org%27s/> certificate, issued by ‘CN=Network
Solutions OV Server CA 2 ,O=Network Solutions
L.L.C.,L=Herndon,ST=VA,C=US’: that
should follow the chain to CN = USERTrust RSA Certification Authority.
Since it's not, that would be where I would look. "sudo
update-ca-certificates -f" if you need to clean up /etc/ssl/certs from old
links.
