ubuntu下云锁卸载出错后无法重新安装的解决办法checking installation environment:

unbuntu下云锁卸载的时候出了点问题，重新安装总是提示已经安装过了：

Welcome to install YUNSUO.

If you encounter any problems during installation, you can use ‘ctrl-c’ to cancel.

checking installation environment:                         [ FAILED ]

Error: Has been installed.

然后卸载又提示：

cat: command_control: No such file or directory

Are you sure to uninstall?(y/n)y

Uninstall Success.

解决办法如下：

vi打开install,找到function check_installed()这个函数，里面的return 1改为return 0，这样就让检查是否安装的时候返回还没安装。

第二步，执行 chmod +x /usr/local/yunsuo_agent/uninstall ，给卸载程序加执行权限。然后执行/usr/local/yunsuo_agent/uninstall就可以成功卸载了。卸载完按照正常程序重新安装即可。
