Ubuntu Server 11.04 has proven to be a venerable server platform, it has nonetheless, reached its end of life on October 28, 2012. Whether or not you are blissfully unaware, end-of-life means that updates and security patches have been discontinued.
As part of the EOL'ing of a release, the mirrors are retired over time. Last week the mirrors for 11.04 were retired from archive.ubuntu.com, which in turn propagated through to the S3 EC2 mirrors. Any person using Ubuntu 11.04 and the S3 mirrors or archive.ubuntu.com will be unable to install software. Over the last week, the Cloud Image team has fielded several questions from distraught users caused by the continued use of 11.04. We strongly suggest that those running Ubuntu Server 11.04 and the recently expired 11.10 and 8.04 LTS upgrade to a supported release to prevent any disruptions to their infrastructure. The current supported LTS is 12.04 with 13.04 being the latest stable release. Ubuntu 10.04 LTS is supported until April of 2015. Those who continue to run expired Ubuntu releases may experience issues and may be required to mitigate the movement of mirrors from the S3 and main archive servers to old-releases.ubuntu.com/ubuntu [2]. While Ubuntu 8.04 LTS and 11.10 are currently available at the main archive and S3 locations, they will be removed anytime, per policy [3] The Symptom For those who are still running 11.04 and are running the 11.04 Cloud Image, you mostly likely have encountered or will encounter some ugly error messages when you try to access the S3 archives for EC2 images in the form of 404 and 403 errors. For example: Err http://security.ubuntu.com natty-security/main Sources 404 Not Found [IP: 91.189.92.201 80] Err http://security.ubuntu.com natty-security/universe Sources 404 Not Found [IP: 91.189.92.201 80] Err http://security.ubuntu.com natty-security/main amd64 Packages 404 Not Found [IP: 91.189.92.201 80] Err http://security.ubuntu.com natty-security/universe amd64 Packages 404 Not Found [IP: 91.189.92.201 80] Ign http://security.ubuntu.com natty-security/main Translation-en_US And.... Err http://us-east-1.ec2.archive.ubuntu.com/ubuntu/ natty-updates/main libapr1 amd64 1.4.2-7ubuntu2.1 403 Forbidden Err http://us-east-1.ec2.archive.ubuntu.com/ubuntu/ natty/main libaprutil1 amd64 1.3.9+dfsg-5ubuntu3 403 Forbidden The reason for this is that when the archives were expired the S3 mirrors themselves replicated the expiration. This is a friendly way to let you know that you should upgrade [3] to the Ubuntu Server 12.04 LTS. If, however, you are unable to upgrade, there are two options. Fix Option 1: sudo sed -i 's,http://.*ubuntu.com,http://old-releases.ubuntu.com,g' /etc/apt/sources.list sudo apt-get -y update If you intend on rebundling the image, you will need to run the following commands to ensure that bundled images retain the settings: dpkg-divert --local --rename --add /etc/cloud/templates/sources.list.tmpl sed -i 's,http://.*ubuntu.com,http://old-releases.ubuntu.com,g' \ /etc/cloud/templates/sources.list.tmpl.distrib \ | sudo tee /etc/cloud/templates/sources.list.tmpl Fix Option 2: Starting new instances If you are starting a new instance, you can configure your cloud-config to default to the new mirrors. The relevent option is the #cloud-config bootcmd: - sed -i 's,\$mirror,http://old-releases.ubuntu.com/ubuntu,g' -e 's,http://security.ubuntu.com.,http://old-releases.ubuntu.com,g' /etc/cloud/templates /sources.list.tmpl.distrib > /etc/cloud/templates/sources.list.tmpl References [1] http://fridge.ubuntu.com/2012/10/28/ubuntu-11-04-natty-narwhal-end-of-life-reached-on-october-28-2012/ [2] http://old-releases.ubuntu.com/ubuntu/dists/ [3] https://help.ubuntu.com/community/PreciseUpgrades -- Ben Howard ben.how...@canonical.com Canonical GPG ID 0x5406A866
