Long and boring? It's seven simple one- or two-sentence steps that fit
in half a screen with very generous spacing. Steps 4 and 5 are not
necessary if you're contributing to an existing project.

It's a Bazaar-style branch, conceptually close to a Git-style branch.
http://doc.bazaar.canonical.com/latest/en/user-guide/core_concepts.html
explains the core Bazaar terminology.

The name would usually describe what you were doing in your branch; see
https://code.launchpad.net/launchpad/ for examples.

Launchpad only accepts pushes using SSH keys, so you need to give Bazaar
an SSH key if you want to push to Launchpad. Random interactive prompts
for authentication are unnecessary hassle.

Ah, indeed. Something has clearly broken with the recent upgrade of the
wiki software. I'll try to fix it.

LXC works fine if you use it correctly, and it's documented well on the
page I linked. If LXD works for you, that's fine, but we can't help with
any issues with it.

As I've said, we will be moving to Git soon, which has clone --shallow
and is fast enough that you probably won't want --shallow anyway.

That sequence of commands works fine, but in general you can't just
randomly skip the entire installation procedure and expect what few
steps you do execute to still function.

Again, if you're going to report an error, it's imperative that you
actually report the details of the error. The only specific problem
you've described so far is that the installation script doesn't work
when your Internet connection is down, which is hardly something that we
can solve.
