What does it mean that linux permissions are insufficient?

Insufficient permissions in Linux means that you do not have the necessary permissions to access a file or resource. Permission levels are divided into users, groups, and others, corresponding to read, write, and execute permissions respectively. Reasons for insufficient permissions may include: you are not the owner, do not belong to the group, or permissions are set to read-only. The workaround is to request permissions, use the chmod command to change permissions, or run the command as root.
