Comment 8 for bug 1047480

Launchpad really doesn't give you a way to pull the "latest" download or md5 hash. There's nothing wrong with using a "hard-coded" version of the release. It means the charm will always work even if upstream changes. Given they release about every 3-4 months it wouldn't be _too_ tedious to update every release, or not. For now, until a more clear release pattern emerges (and development settles) I would just hard-code "17213009a326a730a9de40b70ce93978" for the md5 hash of the tar.gz download from launchpad (https://launchpad.net/chive/1.1/1.1/+download/chive_1.1.tar.gz) So it would look something like this:

chive_file=`ch_get_file "https://launchpad.net/chive/1.1/1.1/+download/chive_1.1.tar.gz" "17213009a326a730a9de40b70ce93978"`

I would be great if they updated their PPA, you could consider contacting the author and asking them to update it.
