Comment 7 for bug 941784

After deployment, there were 18 cases when retries were used:

$ grep -l -a "apt-get failed" /var/lib/jenkins/slave-i-* | wc -l
18

Of them,

$ grep -l -a -E "apt-get failed.+aborting" /var/lib/jenkins/slave-i-* | wc -l
10

still failed at the end.

Final failure errors were like:

W: Failed to fetch http://us-east-1.ec2.archive.ubuntu.com.s3.amazonaws.com/ubuntu/dists/natty-updates/universe/binary-amd64/Packages 403 Forbidden

I.e. it's the same infamous 403 error we tried to get rid of with S3 mirror.
