Hi,
while trying to install some packages via apt-get in a Windows Azure Ubuntu 12.04 VM, I am getting sporadic error while fetching packages, e.g.:
Failed to fetch http://azure.archive.ubuntu.com/ubuntu/pool/main/m/mysql-5.5/mysql-common_5.5.35-0ubuntu0.12.04.2_all.deb 503 Service Temporarily Unavailable
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
A workaround is to change the repository in /etc/apt/sources.list from azure.archive.ubuntu.com to whatever else official ubuntu mirror, like de.archive.ubuntu.com.
What is going on?
