I am trying to download the calibre source code using Bazaar via the command:

bzr branch lp:calibre

In doing so, I get the message:

You have not informed bzr of your Launchpad ID, and you must do this to
write to Launchpad or access private data.  See "bzr help launchpad-login".

And then nothing. I don't get an error message. It just keeps blinking and is stuck.

After a long time this is what is displayed:

Branched 12247 revisions.

But, if I go into the calibre folder it is empty. What am I doing wrong here?

Please cd inside the directory and paste the output of this command: bzr status; bzr checkout . – janos Jun 8 '12 at 19:19

It sounds like it has created a branch without a working tree. If so, you should see a .bzr directory in the calibre directory. To create a working tree, run bzr checkout in the branch.

The message you get about Launchpad ID is only a warning and you can ignore it for now.

It is normal that a branch operation takes long, keep in mind that it downloads the full history of the Calibre project.

The last message Branched N revisions indicates that the operation was successful. If you did this inside a shared repository that is configured with the --no-trees option then it is normal that the calibre directory contains only a .bzr directory, as in this configuration Bazaar will not create working trees. To create the working tree use the bzr checkout . command (notice the . (dot) at the end).

If you don't need the full history you can get the files much faster using so-called light-weight checkouts like this:

bzr checkout --light lp:calibre

Although this will speed up the branching process, all history operations like bzr log etc will take longer, as Bazaar will need to fetch data from Launchpad.
