本文介绍了解决在使用ROS系统时遇到的证书错误问题。当尝试初始化ROSdep时，可能会遇到因证书问题导致无法下载默认源列表的情况。文章提供了一种解决方案，通过重新哈希证书来修复该问题。

error:

~$ sudo rosdep init
[sudo] password for yyd: 
ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list

solution:

#There's something odd about how the certificates on the TX1 image were installed. 

sudo c_rehash /etc/ssl/certs

result:

~$ sudo c_rehash /etc/ssl/certs
Doing /etc/ssl/certs
