did you remove the cache directory? `rm -rf /var/cache/yum` – Mike Marseglia Sep 19 '19 at 19:01

1Yes.. but it did not have cached anything under /var/cache/yum folder instead it was in /var/cache/dnf , by doing sudo rm -rf /var/cache/dnf/* and then yum update resolved the issue – ras Sep 19 '19 at 19:04

RHEL 8 is based on dnf (dandified YUM), so you would want to use "dnf clean cache" or "dnf clean all" instead of yum. Additionally, if that didn't work, you would want to look in /var/cache/dnf rather than /var/cache/yum.

Using `yum` doesn't make a difference. It will redirect to `dnf` and do the same. One can even install `yum` or create an alias for it that points at `dnf` but even that isn't needed. – Nasir Riley Mar 11 '20 at 01:08

Use sudo yum or elevate to root for aws rhel 8; no need to use dnf (although trying to download a package using dnf did make me realize I didn't have enough permissions).

With RedHat 7 or 8, one way to clean all those caches is to run this command as Sudo
sudo rm -rf /var/cache/yum/*
For those wondering why “yum clean” or “yum clean all” does not clean/remove all caches. It is because “yum clean” or “yum clean all” only removes the cache of repositories which are enabled in /etc/yum.repos.d/*.repo. In other words, cache that are either presently deactivated or from previous RedHat version will not be clear. This is per Yum manual. Which reads: « Note that "all files" in the commands below means "all files in currently enabled repositories". » Source at http://man7.org/linux/man-pages/man8/yum.8.html#CLEAN_OPTIONS
