Oracle Linux 8 RPM installation broken

Byetzion 16/02/202416/02/2024

I got the following error message when attempting to upgrade RPM packages: Oracle Linux 8 introduced a bug with a package called rpm-plugin-selinux (details: rpm-plugin-selinux-4.14.3-28.0.1.el8_9) which prevents RPM packages from being installed correctly, either by dnf/yum or manually.

Forgot to mention kernel update

net-snmp broken in RHEL (and Centos, of course) – diskio

Byetzion 09/06/2007

ACFS was a good-enough…
