Ubuntu8.04 failure to use the "apt-getupdate" command Solution

The update source is updated on Ubuntu8.04 today. After updating the source, enter sudoapt-getupdate in the terminal. However, this command does not seem to work and cannot be updated. The terminal is displayed as E: unable to obtain lock/var/lib/apt/lists/lock-open (11 Resourcetemporarilyunavailable) E: unable to add Status List Directory

The update source is updated on Ubuntu 8.04 today.

After updating the source, enter sudo apt-get update in the terminal. However, this command does not seem to work and cannot be updated ---

Terminal display
E: unable to obtain the lock/var/lib/apt/lists/lock-open (11 Resource temporarily unavailable)
E: Unable to lock the Status List Directory

So I searched for a solution online and quickly found a solution: Delete the/var/lib/apt/lists/lock file, the specific command is sudo rm/var/lib/apt/lists/lock.

After deleting the lock file, enter sudo apt-get update in the terminal and press Enter. The update starts normally. (To run the Administrator command, use sudo Ubuntu to hide the root user by default)

It took me about 50 minutes to update Ubuntu today. It was really slow. I use the following update sources. I wonder if there is any faster update source?
