+    ### Method #1: Check for Running Processes

+    You could terminate the process using
+
+    ```bash
+    sudo kill <PID>
+    # from above picture PID is second col from left. PID is 7991 and 7993 [Yours will be different]
+    ```
+
+    ### Method #2: Remove Lock Files Manually
+
+    !!! warning ""
+
+    Run the below commands and then attempt to run `sudo apt update`
+
+    ```bash
+    sudo rm /var/lib/apt/lists/lock
+    sudo rm /var/cache/apt/archives/lock
+    sudo rm /var/lib/dpkg/lock
+    sudo rm /var/lib/dpkg/lock-frontend
+    ```
+
+    Above should solve the problem, but if doesn't, run `sudo dpkg --configure -a` then try to `sudo apt update`
