CentOS 8 and versionlock not behaving as expected

[MargoK]

Just started playing around with CentOS 8 and I'm seeing some odd behavior using the versionlock plugin. Basically I'm building a docker container and I'm starting with centos:centos8.1.1911. I make sure all the repos I need are enabled, install the versionlock package and setup my versionlock.list file (basically following the same process I've been doing for CentOS 7). What I'm seeing is that a handful of packages have been downgraded from what I have in my versionlock.list file. What am I missing?

I'll use the binutils package for this example

This is what I have in the versionlock.list file (and yes this is the file specified in the versionlock.conf file)

Code: Select all

$ grep binutils /etc/dnf/plugins/versionlock.list 
binutils-2.30-58.el8_1.1.x86_64

This what is actually installed

Code: Select all

$ yum list installed binutils
Installed Packages
binutils.x86_64                                        2.30-58.el8.0.1                                        @System

This is what's available

Code: Select all

$ yum list available binutils

Now when I try and run yum update it tells me there's nothing to do (even though I have the _1.1 version specified in the versionlock.list file

Code: Select all

# yum update

Nothing to do.
Complete!

If I clear that entry in the versionlock.list file and run the update again it works

Code: Select all

# yum versionlock delete binutils
