My installation of RHEL 8 lacked a couple of required libraries and programs, which tl-setup noted.

I expected to see tl-setup offering to install these dependencies for me, but I did not. From the tlsetup.log file, I could see this:

While RHEL 8 retains the "yum" name for the package manager, they replaced the yum implementation with dnf.

> # head -n 2 /usr/bin/yum
> #!/usr/libexec/platform-python
> # The dnf executable script.

Also of note in the above snippet - dnf is implemented on top of the "platform python", which is python3.6 in the RHEL 8 beta. I could find no packages that provide an Python 2 API for dnf or any packages providing yum API:s.

> # yum search dnf python

libdnf ships /usr/lib64/libdnf.so.2, nothing explicitly Python-related.
