libstdc++6 && gcc-9 for ubi8-minimal distro

Question

I cannot seem to install gcc-9 or libstdc++6 for ubi8-miniman distro.

error: No package matches 'gcc-9'

I know there is a enablerepo= which I can use to point towards the repo for packages that are not inside the minimal one, but the repos I tried so far were not correct.

Maybe somebody had a similar challenge and solved it?

Answer 1

The minimal base image also only comes with a minimal package manager. As you can read in RH's blog post on this the minimal image has the following:

Minimal - Designed for applications that contain their own dependencies (Python, Node.js, .NET, etc.)

Minimized pre-installed content set

No suid binaries

Minimal package manager (install, update, and remove)

So you can only install what's available more or less. You can enable and disable repos but only from the following list:

You can look up all packages available for those here but there will only be gcc in version 8.5 available.
