- python-software-properties

This package has been deprecated and it is already replaced by software-properties-common.

It is causing fail during Streisand installation on Ubuntu 18.04. Should be either commented out or replaced by newer package name

Same problem on debian 9:
fatal: [Existing.server.ip]: FAILED! => {"changed": false, "msg": "No package matching 'python-software-properties' is available"}
Is there a solution?
EDIT: after fixing ansible and the pc I don 't get this error (but an another).

These are "existing server" or "localhost"? Streisand currently only supports Ubuntu 16.04 as a target system. If you're interested in helping update target support to Ubuntu 18.04, check out #1453.

I doubt that Debian as a target will be supported; if you can pick Debian, usually you could also pick Ubuntu. PRs welcome, but please show your work early; I don't want you to get stuck later.

8th option existing server for me, anyway i forgot to change network (client and server were in the same).
Now I need to use a custom ssh port, later maybe i will have again this problem.

Indeed I tried with local host and I have the same error.

Could you upload a streisand-diagnostics.md file from one of the failures?

[root2185]

I did several attempts this one should be the one with localhost, so the problem is python-software-properties.
(I still waiting for a custom shh port solution #1483).
Is it possible to use python3? So i can use the package python3-software-properties.
Or somehow install/use python-software-properties on python2?
