Deja-dup should not propose ssh as storage location when python-paramiko is not installed

[autra]

As far as I understand things, duplicity uses paramiko for ssh2 protocol. But python-paramiko is only a suggestion for duplicity package.

When the user does not have this package installed on its system, he/she can still select "ssh" as storage location method in deja-dup.

So I guess deja-dup should explicitely depend on python-paramiko, or make ssh option unavailable if the package is not present.

Option 2 would be preferred, as the user will get a chance to know something is missing.

This is still the case in Ubuntu 16.04.

<Vej> Could someone please triage https://bugs.launchpad.net/ubuntu/+source/deja-dup/+bug/1472598 and set the importance as "Low" (Bug that affect a non-essential aspect and limited scope of the application)? I want to forward this to upstream afterwards.

Did you actually experience an issue with SSH? Deja Dup doesn't use duplicity's normal ssh backend, it connects to ssh servers through its gio backend. So python-paramiko isn't used in the normal cases.

I'll mark this as invalid, but if I'm wrong, please re-open.
