Today I fired up my LapTop, logged into Ubuntu and ran

 sudo apt-get update 

Then this happened.

Any ideas what could cause this?
Could it be that those links are not working anymore? If so where can I find new ones?

Thank you <3

The core issue is that the Mirror in use by the ir.archive.ubuntu.com DNS Round Robin that you landed on is not working properly.

About 2 minutes ago relative to this post, the notification of this mirror timing out to the Ubuntu Mirrors team (part of Canonical's Systems Administration teams) indicating that they have, for now, removed the IP from the round robin rotation due to the timeouts (for now).
