Hi,

I'm doing some tests of upgrading CentOS from 7 to 8 reading this
step-by-step guide:
https://netshopisp.medium.com/how-to-upgrade-linux-servecentos-7-to-centos-8-ec2db96a189b

I'm trying this upgrade in a VM, so I can save "snapshots" and
restart in a past saved point. However, all my test ends wrong, exacly in Step 4
when I run "rpm -e `rpm -q kernel`". Then, systems says that some
packages are kernel dependencies. After I remove that dependencies, I can't
remove kernel...

Anybody has tested process upgrade from 7 to 8?

Thanks.
