Dear Ian Hinder

Many Thanks

I'm searching google, but still not resolved

My Ubuntu version: Ubuntu 14.04.5 LTS
 and
curl --version: curl 7.52.1 (x86_64-pc-linux-gnu) libcurl/7.52.1 OpenSSL/1.0.2l zlib/1.2.8
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp

Hi,

(Please can you leave users@einsteintoolkit.org in the CC, with "reply all", so that others will benefit from and contribute to the discussion?  Thanks!)

OK, that all looks good.  This is weird.  Can you check that the right host is being connected to with

host raw.githubusercontent.com

and also that you can connect using openssl:

openssl s_client -connect raw.githubusercontent.com:443

You should see something like 

    Verify return code: 0 (ok)

at the end.  (Use ctrl-C to exit from the connection).  If you get some error message, please post it here.


With Best Regards!!!

After installing all requirements, I just typed the following commands in Ubuntu terminal: 

!curl -kLO https://raw.githubusercontent.com/gridaphobe/CRL/ET_2018_02/GetComponents
!chmod a+x GetComponents

Due to my machine failure I'm reinstalling Toolkit, but I faced the following error. 

curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol



Hi,

I copied that command and ran it on Mac OS and Linux, and it worked OK.  What version of Ubuntu are you using?  You can get this from the output of

cat /etc/issue

Can you send the output of

curl --version

A quick google search says that that particular error message occurs if you try to access an http server with https.  Is it possible that there is some firewall or redirection happening on your network to prevent you from accessing https servers?
