Fix the "Installing an External Smart Proxy Server on Debian" guide

[ekohl]

https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html contains many thing that are incorrect. I think some of these also affect Foreman without Katello installations.

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#system-requirements_smart-proxy

The users apache, foreman and postgres will not be needed. apache doesn't even exist on Debian (it's www-data), but no Apache is installed. foreman can also be dropped from the RPM-based guides since it doesn't matter. postgres is only relevant on content proxies.

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#capsule-ports-and-firewalls-requirements_smart-proxy

Port 5646 is irrelevant on non-Katello installs.

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#capsule-ports-and-firewalls-requirements_smart-proxy

This whole chapter is irrelevant on non-Katello since port 5646 isn't used.

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#enabling-connections-to-capsule_smart-proxy

Ports need updating

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#configuring-repositories-proxy-deb_smart-proxy

Always lists buster as the distro, but that doesn't work on Ubuntu. I'd recommend using what's on https://docs.theforeman.org/nightly/Quickstart_Guide/index-foreman-deb.html#configuring-repositories_foreman since that also sets up Puppet, which is required.

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#installing-the-satellite-capsule-server-packages_smart-proxy

Is wrong, needs to be what's @ https://docs.theforeman.org/nightly/Quickstart_Guide/index-foreman-deb.html#installing-the-satellite-server-packages_foreman

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#synchronizing-the-system-clock-with-chronyd_smart-proxy

It's odd to refer to RHEL docs for Debian users.

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#configuring-capsule-default-certificate_smart-proxy

Completely incorrect on non-Katello installs

• [ ] https://docs.theforeman.org/nightly/Installing_Proxy_on_Debian/index-foreman-deb.html#enabling-openscap_smart-proxy

We don't package the OpenSCAP plugin for debs.

https://github.com/theforeman/foreman-documentation/pull/651 made a start on the network ports.

@Lennonka I didn't find it during today's meeting, but I did start to open concrete issues for guides. This issue is old and some have been addressed. The links are all dead now, but would this be a good format to make guides ready?

By now I would propose to open a PR to mark the guide as ready and then in the review go through the various sections.

[Lennonka]

@ekohl I'm not sure what you mean by "this" as a good format. Do you mean creating an issue for each guide and marking the sections that need fixups for Debian? Something like that?

Probably yes. We can try one and take it from there.

[ekohl]

Yes, that's what I indeed meant.
