Hi, we would like to use Python 3 on the default installation instead of Python 2 on Fedora 22.
According to FESCo, we should firstly focus on the cloud image.
From that perspective, your package is considered as IMPORTANT - that means, is has to be updated to Python 3, for our intention come true.
The goal here is, that at least for F22 you should provide python3- prefixed subpackage.
Please, help us update to Python 3 flawlessly.
Check if upstream already support Python 3, if yes, use it and add the support to the package.
If upstream doesn't support Python 3 yet, encourage it to do so by sending patches and offering your help.
When upstream is dead or unwilling to support Python 3, say so and we can solve the problem together.
Chances are, that you ARE the upstream. In that case, everything is easier, just do it yourself.
There is a table on wiki, that should list your package. Chances are, that you can see an upstream link that covers the problem. Anyway, please update the table with information you know.
I offer my help with this task, so if you have no idea, how to work on this, or it is just not your priority, don't hesitate to ask for help.
(As you've already realized, this is a bulk text, so if something is not quite exact about your package, sorry for that, just ask)
cloud-init does no longer need cheetah and that old thing is probably never going to be Python 3 compatible anyway.
