[dput-ng-maint] Bug#863723: dput-ng: skip `please login: To accept ssh-rsa hostkey [...]`

[Nico Schlömer]

Package: dput-ng
Version: 1.8
Severity: wishlist

I'm using dput-ng for submitting builds to launchpad via sftp. Every time I
submit, I have to answer the question
```
please login: To accept ssh-rsa hostkey 6b03de9833252318a646b34722cd54f2 for
ppa.launchpad.net type "yes": [yes, no]:
```
That makes it impossible to dput in a cron job. I've played around with my SSH
settings, but that doesn't seem to have anything do with it.

Is there a way to skip the above question?

Cheers,
Nico
