gnutls_handshake() failed问题解决方法

编译openwrt时候遇到此问题，原因貌似是gnutls的协议不支持，可以安装openssl来解决此问题：

下面是网上找到的解决方法：

Got reason of the problem, it was 

gnutls

 package.
It's working weird behind a proxy. But 

openssl

 is
working fine even in weak network. So workaround is that we should compile 

git

 with 

openssl

.
To do this, run the following commands:

sudo apt-get update
sudo apt-get install build-essential fakeroot dpkg-dev libcurl4-openssl-dev
sudo apt-get build-dep git
mkdir ~/git-openssl
cd ~/git-openssl
apt-get source git
dpkg-source -x git_1.7.9.5-1.dsc
cd git-1.7.9.5

(Remember to replace 

1.7.9.5

 with
the actual version of git in your system.)

Then, edit 

debian/control

 file
(run the command: 

gksu
gedit debian/control

) and replace all instances of 

libcurl4-gnutls-dev

 with 

libcurl4-openssl-dev

.

Then build the package (if it's failing on test, you can remove the line 

TEST=test

 from
the file 

debian/rules

):

sudo dpkg-buildpackage -rfakeroot -b

Install new package:

i386: 

sudo
dpkg -i ../git_1.7.9.5-1_i386.deb

x86_64: 

sudo
dpkg -i ../git_1.7.9.5-1_amd64.deb

执行完成后重新编译即可
