Note: This solution is not just limited to codecommit but also for other Ubuntu gnults_handshake related issues.
If you have AWS cli installed in ubuntu 14.04 and working with AWS codecommit, you are likely to get “gnutls_handshake() failed” error when you try to clone a repository created in codecommit. Do not worry about it, we have a solution for it.

问题似乎是 Ubuntu gnutls_handshake 的问题。

解决方案重新编译 git

使用 libcurl-openssl-dev 去替换 gnutls

• 安装必要的依赖及环境
  sudo apt-get install build-essential fakeroot dpkg-dev
• 建个目录放 新编译的 git
  mkdir ~/git-rectify
• 获取 git 源码
  cd ~/git-rectify
sudo apt-get source git
• 安装 git 的依赖
  sudo apt-get build-dep git
• 安装 libcurl
  sudo apt-get install libcurl4-openssl-dev
• 进入 git 目录，这里目录名视你安装的版本
  cd git-2.7.4/
• 修改两个文件后重新编译 git
  vim ./debian/control # 把libcurl4-gnutls-dev 修改为 libcurl4-openssl-dev
  vim ./debian/rules # 把TEST=test整行删除
  sudo dpkg-buildpackage -rfakeroot -b
• 回到上一级目录，安装编译好的安装包
  cd .. # 也就是在 ~/git-rectify 目录下
  sudo dpkg -i git_2.7.4-0ubuntu0.4_amd64.deb

源码安装 git

这里只是记录一下源码安装 git 的步骤。
git clone https://github.com/git/git.git
切换到相应的版本 tag
git checkout -b v2.22.0
sudo apt-get install libssl-dev
根据 doc 文档 说明的安装命令安装即可。
