Why do you check for errors only on the next-to-last command? You could write

apt-get update &&
echo root:passwd | chpasswd &&
add-apt-repository ppa:juju/pkgs &&
apt-get update &&
apt-get install juju

Also, why the first apt-get update?

the first apt-get is because when a cloud vm first launches on a cloud the apt list is stale/partial. If you try to install things, it will usually fail.

Regarding the question about why am I only doing && on the last line? because I was just getting started. I usually set errexit and don't use && at all.

In trying to debug these I decided to implement https://github.com/angst/cloudtee ... it helps debug failures.
