document steps to obtain "LibreSSL libtls" on Ubuntu

[reschke]

...because it doesn't seem to be as simple as it should be :-).

ok - found https://github.com/rpki-client/rpki-client-portable/blob/master/build_libtls.sh

You should not use that. This is only for the CI system there is no warranty that this will not eat your system.

[cjeker]

there is libretls and there are libretls packages for e.g. debian available. Push ubuntu to pull that package into their packaging system.

[reschke]

The plan is to use it in a docker image with the sole purpose of building rpki-client.

[cjeker]

why don't you use https://github.com/rpki-client/rpki-client-container?

[reschke]

Because company policy requires a specific base Ubuntu image for everything.

Ubuntu 22.04 should have a package for libtls (libtls22 and libtls-dev).
I have no Ubuntu install to try this on but I guess it will just work.
