最近遇到了一个恼火的问题，在Ubuntu上尝试用svn命令checkout一个https的repository时遇到个错误信息：

svn: E175002: Unable to connect to a repository at URL 'https://domain/svn'svn: E175002: OPTIONS of 'https://domain/svn': SSL handshake failed: SSL error: Key usage violation in certificate has been detected. (https://domain)

Solution:

安装libneon库：

sudo apt-get install libneon27

替换link：

sudo mv /usr/lib/libneon-gnutls.so.27 /usr/lib/libneon-gnutls.so.27.oldsudo ln -s /usr/lib/libneon.so.27 /usr/lib/libneon-gnutls.so.27
