xterm报错如下:
Attaching to process 9636
Could not attach to process. If your uid matches the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.
解决方案:
打开文件: /etc/sysctl.d/10-ptrace.conf
修改:kernel.yama.ptrace_scope = 1 改为0
接着:sudo service procps restart
完成!
