How do I fix a "User timeout caused connection failure" error?

Question

I'm following these instructions - How do I configure juju for local usage? and all appears well until :

juju deploy mysql - which gives

2012-08-01 16:14:58,560 INFO Searching for charm cs:precise/mysql in charm store
User timeout caused connection failure.
2012-08-01 16:15:28,592 ERROR User timeout caused connection failure.

~/juju/samples/charms/ is empty.

juju bootstrap completed within 10 secs which I suspect is not correct

geme@GEME1:~$ juju bootstrap

The bootstrapping quickly is to be expected. In most environments the bootstrap will actually spin up a machine, when you're working with a local deployment it just creates the first LXC container and sets up networking. So this typically takes 10-20 seconds. The magic happens on the first deployment, as explained in this local configuration question, this is when Juju downloads ~300MB server image and creates the "master container" which all future deployments are based on.

Now, the error your receiving appears to state that there's a timeout trying to reach the Juju Charm store. I wasn't aware of any outages, but it might be because you're behind a proxy or some other kind of networking issue/timeout. I'd recommend trying again (juju destroy-environment -e local) then re-bootstrap.

If you're having proxy issues, you can download charms locally using Bazaar:

mkdir -p ~/charms/precise
cd ~/charms/precise
bzr branch lp:charms/mysql
juju deploy --repository=~/charms local:mysql

While the directory can be anything, the important item to follow is each charm needs to be in a series folder (following the Ubuntu release names). Outside of that you use --repository which instructs Juju to search here for charms, and the local: prefix tells Juju that the deployment will be from that local --repository path.

How do I fix a "User timeout caused connection failure" error?
