Solution 1: Check whether there are two Apt

Force unlock, and enter the command in the terminal

Sudo RM/var/Cache/APT/archives/lock

Sudo RM/var/lib/dpkg/lock

Solve the problem.

This problem is actually caused by Operation problems. You must have forcibly shut down the terminal (for example, CTRL + Z), so you cannot obtain the exclusive lock due to running, the solution is to develop a good habit. The terminal often uses Ctrl + C to terminate the operation, and the same problem will not occur in the future.

Solution 2: Disable the apt-Get process forcibly terminated by you.

Enter PS-Aux on the terminal to list processes. Find the process P containing apt '-Get or wgetID,
Sudo kill PID directly. Solution.
