In Ubuntu system operation, we often use the system permissions, because of insufficient permissions, resulting in some operations very troublesome.

2. Find the line where our user name is located, and modify the ID value of the current user inside. For example, my current user is crystal.

3. Then find the Crystal:x:1000:1000:crystal:/home/linuxidc:/bin/bash to change two 1000 to 0.

4. The result of the final change is:

   Crystal:x:1000:1000:crystal:/home/linuxidc:/bin/bash

   Finally, the Ubuntu system to log off, and then in the login username and enter your own user name and password, so landing is the root authority. This is because root has an ID value of 0.
