Authentication failure while updating

Question

After it downloaded the file, it reports an authentication failure and skips to the next task.

After finishing all downloads it reports that I should check my internet connection.

Just to make sure, I ran update-manager from terminal but still the same problem persisted.

Result of apt-get upgrade:

E: Failed to fetch http://ubuntu.01link.hk/pool/main/a/app-install-data-ubuntu/app-install-data_14.04.1_all.deb  Hash Sum mismatch

E: Failed to fetch http://ubuntu.01link.hk/pool/main/s/software-center/software-center_13.10-0ubuntu4.1_all.deb  Hash Sum mismatch

Everything else downloaded perfectly the only problem is with app-install-data and software-center. Also, it goes up till 100% then it shows the error. — いちにち, Jul 11 '14 at 15:28
Can you open a terminal and type sudo apt-get update && sudo apt-get upgrade, and post the results? — Mitch, Jul 11 '14 at 15:31

I finally got it to work. Tumbleweed's post here pointed me to what went wrong. I changed the mirror to Main Server and it all worked fine!

I suppose even this can be done, but changing the mirror is a better and more permanent solution.
