今天在使用pycurl加上代理后出现了一下的错误内容：
Traceback (most recent call last):
File "xici.py", line 19, in <module>
c.perform()
pycurl.error: (35, 'gnutls_handshake() failed: An unexpected TLS packet was received.')
于是乎google了一番，找到了以下的解决方法：
首先先确定自己安装的pycurl依赖的软件包类型：
访问下载自己接下来要编译的版本，里面三个文件都要下载
将三个文件放到pycurl_make文件中，开始编译安装：
1. sudo apt-get install build-essential fakeroot dpkg-dev
2. mkdir ~/pycurl_make
3. cd ~/pycurl_make
4. sudo apt-get source python-pycurl
5. sudo apt-get build-dep python-pycurl
6. sudo apt-get install libcurl4-openssl-dev
7. sudo dpkg-source -x pycurl_7.43.0.1-0.2build2.dsc
8. cd pycurl-7.43.0.1
9. sed -i 's/libcurl4-gnutls-dev/libcurl4-openssl-dev/g' debian/control
10. sudo dpkg-buildpackage -rfakeroot -b
11. sudo dpkg -i python3-pycurl_7.43.0.1-0.2build2_amd64.deb
之后在查看版本：
