[Bug 1750633] Re: signer and verifier have been deprecated

[Robert Mader]

Hej Kenneth, thanks for the answer. I agree that this is a sufficient
workaround, but for an LTS version of Ubuntu, I think it would be
worthwhile considering backporting this fix.

People will use Ubuntu 18.04 for many years to come and many will hit
this issue, especially people using it on servers and doing backups with
duplicity. Installing packages from pip makes updates more complicated
and dangerous and is certainly not the desired state for backup
solutions. Maybe the maintainer of paramiko, @jbouse, can comment on
that?
