Hi list, I'm struggling with git connecting to Github. The problem might be SSL/TLS related. https://githubengineering.com/crypto-removal-notice/ I suspect that my setup still uses tlsv1 or tlsv1.1. I've tried to explicitly set git to use tlsv1.2 in my .gitconfig file like this: [http] sslVersion = tlsv1.2 I've tried to re-compile git with OpenSSL and GnuTLS. All give the same error. git clone https://github.com/OnionIoT/source.git Cloning into 'source'... * Couldn't find host github.com in the .netrc file; using defaults * Trying 192.30.253.112... * TCP_NODELAY set * Connected to github.com (192.30.253.112) port 443 (#0) * ALPN, offering http/1.1 * Cipher selection: ALL:!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4:@STRENGTH * successfully set certificate verify locations: * CAfile: /etc/ssl/certs/ca-certificates.crt CApath: /etc/ssl/certs * error:1409442E:SSL routines:ssl3_read_bytes:tlsv1 alert protocol version * Curl_http_done: called premature == 1 * stopped the pause stream! * Closing connection 0 fatal: unable to access 'https://github.com/OnionIoT/source.git/': error:1409442E:SSL routines:ssl3_read_bytes:tlsv1 alert protocol version lev@jive:~/git$ unset GIT_SSL_VERSION lev@jive:~/git$ git clone https://github.com/OnionIoT/source.git Cloning into 'source'... * Couldn't find host github.com in the .netrc file; using defaults * Trying 192.30.253.112... * TCP_NODELAY set * Connected to github.com (192.30.253.112) port 443 (#0) * ALPN, offering http/1.1 * Cipher selection: ALL:!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4:@STRENGTH * successfully set certificate verify locations: * CAfile: /etc/ssl/certs/ca-certificates.crt CApath: /etc/ssl/certs * error:1409442E:SSL routines:ssl3_read_bytes:tlsv1 alert protocol version * Curl_http_done: called premature == 1 * stopped the pause stream! * Closing connection 0 fatal: unable to access 'https://github.com/OnionIoT/source.git/': error:1409442E:SSL routines:ssl3_read_bytes:tlsv1 alert protocol version I can connect to other git servers without any error. This is a debian stable system with the following components: git version 2.11.0 libcurl 7.52.1 OpenSSL 1.0.2l Is there any way to know what is the exact protocol used? Are there any workaround, fix for this issue? Any help welcome. Thank you, Levente -- Levente Kovacs Senior Electronic Engineer W: http://levente.logonex.eu
