Apt update failing on AWS us-east-1 instances

Support and Help
1

I’m seeing the following error when running apt update on us-east-1 instances in AWS:

E: Failed to fetch http://us-east-1.ec2.archive.ubuntu.com/ubuntu/dists/noble-updates/universe/binary-amd64/Packages.xz  File has unexpected size (1568696 != 1568516). Mirror sync in progress? [IP: 18.232.150.247 80]

It seems like the problem started this morning. I am able to work around it by replacing the default mirror (e.g. via sed -i 's/http:\/\/us-east-1.ec2.archive.ubuntu.com\/ubuntu\//http:\/\/mirror.cogentco.com\/pub\/linux\/ubuntu\//g' /etc/apt/sources.list.d/ubuntu.sources).

This also happened a couple of months ago, starting on Saturday 21Mar, and wasn’t resolved until people returned to the office the following Monday. The status page at https://status.canonical.com/ doesn’t show any incidents today. Is there any way to flag this for the folks responsible for maintaining the AWS mirrors?

sudo rm -rf /var/lib/apt/lists/* && sudo apt-get clean && sudo apt-get update

Should do it

This error is showing up on brand new instances - I don’t think there’s an apt cache to clear.

Have you logged a ticket to the AWS support? You are using their repo

Hm, that is an idea - I thought Ubuntu maintained the AWS mirrors since status.canonical.com lists other cloud mirrors but maybe it’s actually AWS maintaining them.
