Comment 1 for bug 1720630

I assume your testing was on a fresh system, not an upgrade?

We have intentionally hidden several cloud providers by default. See this wiki page for the explanation and how to unhide them:

But on upgrades, your old settings shouldn’t be affected. If that’s the case, this is a new bug. Otherwise, I’ll mark this bug closed as intentional behavior.

(You also shouldn’t have to manually install python-boto and such anymore. If you have S3 set up in deja-dup, we’ll prompt you to install what we need now.)
