Okay I found why it fails, I was misunderstood how distro package works, it seems distro.id() is NOT always same output as ID in /etc/os-release.
On /etc/os-release, OEL is ID="ol", but distro.id() returns oracle:

[vagrant@localhost ~]$ /opt/scylladb/python3/bin/python3
Python 3.8.3 (default, May 15 2020, 00:00:00) 
[GCC 10.1.1 20200507 (Red Hat 10.1.1-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import distro
>>> distro.id()
'oracle'

No vulnerable release.

@penberg why is the promoter re-adding the backport candidate label?
