Root Cause

The process does not have the necessary file system permissions to open the file, often due to running as a non-root user.

generic

中文

进程没有打开文件所需的文件系统权限，通常由于以非root用户运行。

Workarounds

  1. 85% success Check permissions before opening and use appropriate user or sudo 
    if os.Geteuid() != 0 { return errors.New("must run as root") }
f, err := os.Open("/etc/shadow")

Dead Ends

Common approaches that don't work:

  1. Running entire application as root 30% fail

    Security risk; better to use capabilities or proper user.
