I was trying to download "curl", but could not do so. As far as I could tell, I did not have the problem last time.

$ wget https://curl.haxx.se/download/curl-7.52.1.tar.gz
--2017-02-18 16:32:21--  https://curl.haxx.se/download/curl-7.52.1.tar.gz
Resolving curl.haxx.se..., 2a00:1a28:1200:9::2
Connecting to curl.haxx.se||:443... connected.
ERROR: certificate common name `anja.haxx.se' doesn't match requested host name `curl.haxx.se'.
To connect to curl.haxx.se insecurely, use `--no-check-certificate'.
Unable to establish SSL connection.

I tried to download it to my Mac, and transfer it to via Cyberduck, but met another message : "connection failed Indicated packet length 1684366188 too large." the same things happened when I attempted to transfer untared folder. Any suggestion?


macOS comes with curl as /usr/bin/curl.

$ /usr/bin/curl -O https://curl.haxx.se/download/curl-7.52.1.tar.gz

This seems to work on my MacBook Air, from a terminal.

You could also try using the --no-check-certificate option with wget, as kindly suggested by the message from wget.

  • Yes, I could download with "--no-check-certificate", sorry that I did not realize that "use `--no-check-certificate'" means an option for wget ... Tks! – Jun Feb 18 '17 at 7:58
