Hi,
I was using yum for years on CentOS servers, and since a few years ago dnf on Fedora desktops. My question is: Is the same yum4 on CentOS 8 that dnf? What should I use? Thanks in advance
yum4 is a thin wrapper on dnf mainly because Enterprise Linux users and scripts are used to the yum commands. You can use either dnf or yum4 on the command line and get the same results.
You mentioned you're familiar with Fedora, so you're probably aware of Application Streams -- but for those reading this thread unfamiliar with AppStreams, I'll add the caveat that dnf behaves differently than yum in this regard.
Here's some background:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/htm...
Right now, the only EL8 AppStream with multiple versions is postgresql, but it looks like several applications are setup for future multiple streams. To see the AppStream packages, run
dnf module list
If you squint carefully, you'll see that you can install either PostgreSQL 10 (the default) or 9.6.
