When running apt-get on an Ubuntu 20.04 LTS AWS EC2 instance in ap-southeast-2, the apt repo is sometimes failing with 503 service unavailable.

1

When running apt-get on an Ubuntu 20.04 LTS EC2 instance in ap-southeast-2, the apt repo is sometimes failing with 503 service unavailable. The instance is using the default apt repo config provided with the Ubuntu image "amazon/ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-20230616", owned by 099720109477. Found from the Ubuntu image locator: https://cloud-images.ubuntu.com/locator/

For example (run via an ansible task):

/usr/bin/apt-get -y -o \"Dpkg::Options::=--force-confdef\" -o \"Dpkg::Options::=--force-confold\"       install

Some of the packages sometimes fail to be fetched with this error. The specific packages and IP addresses might vary, the error is the same Failed to fetch ... 503 Service Unavailable [IP: 3.26.8.197 80].

failed: E: Failed to fetch http://ap-southeast-2.ec2.archive.ubuntu.com/ubuntu/pool/main/[...]_amd64.deb  503  Service Unavailable [IP: 3.26.8.197 80]
E: Failed to fetch http://ap-southeast-2.ec2.archive.ubuntu.com/ubuntu/pool/main/[...]_amd64.deb  503  Service Unavailable [IP: 3.26.8.197 80]

Is this an issue with the apt repo at http://ap-southeast-2.ec2.archive.ubuntu.com or is there something I need to change on the EC2 instance?

The repos are hosted on ubuntu.com so it's an Ubuntu issue and not AWS.

I get similar problems on a sandpit EC2 in ap-southeast-2 I just spun up to test:

ap-southeast-4 (Melbourne) is fine just now though, so looks like it may be local to Sydney:
