windows上是没有问题,ubuntu上一直报错,百度出来的解决办法一点用都没有。。。照着改了老半天,一直是两种错误提示来回报错
1.Failed to connect to github.com port 443: Connection timed out
2.gnutls_handshake() failed: The TLS connection was non-properly terminated.

Update failed
			unable to access 'https://github.com/xxxxxx/xxxxxx/': Failed to connect to github.com port 443: Connection timed out

或者

Update failed
			unable to access 'https://github.com/xxxxxx/xxxxxx.git/': gnutls_handshake() failed: The TLS connection was non-properly terminated.

我最后是关了所有的代理,不使用代理了,报错443。然后发现一个地方没有勾起来。。。。勾起来之后就一切正常了
