wget -r -p -np -k http://archive.openwrt.org/barrier_breaker/14.07/ramips/mt7620a/packages/
When downloading site https:
ERROR: Certificate .c.ssl.fastly.net Common name `* 'does match Not bootstrap.pypa.io requested Host name`'.
The To Connect to bootstrap.pypa.io insecurely, use `--no-Check-Certificate '
unable to establish SSL connection.
wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py
because wget when using HTTPS protocol, the default will be to verify the site's certificate, but the certificate validation often fails. Plus the "--no-check-certificate" option, you can exclude this error.
