In the above graphic, you can see the planned Red Hat Enterprise Linux 8 life cycle. Looking at the line for 8.4, there is a period of time where it is an actively developed Minor Release. 8.4 is also an eligible Extended Update Support (EUS) release, meaning that in the later part of 2021, when RHEL 8.5 is released, those wishing to remain on RHEL 8.4 can subscribe their systems to an EUS repository using Subscription Manager. The EUS repository will receive updated packages, as mentioned previously, until early 2023.

I'm having this issue upgrading my lab server from 8.5 to 8.6. I removed three of the packages it was complaining about but it still chokes on some other packages and the only way to get the update to go through is to use the --nobest option. I'd rather not have to rely on this going forward with production servers (this just indicates to me that 8.6 is corrupted). I only have the following repos enabled:Updating Subscription Management repositories.

You should always check for a package in the Linux distro repository first. It is possible the package available may not be the latest version, however, enabling autoupdate will ensure the Linux Agent will always get the latest update. Should you have issues installing from the package managers, you should seek support from the distro vendor.
Enable agent auto update.This version of Debian doesn't have a version >= 2.0.16, therefore AutoUpdate isn't available for it. The output from the above command will show you if the package is up-to-date.
EUS is not supported on RHEL Extras. This means that if you are installing a package that is usually available from the RHEL Extras channel, you will not be able to do so while on EUS. The Red Hat Extras Product Life Cycle is detailed on the Red Hat Enterprise Linux Extras Product Life Cycle - Red Hat Customer Portal page.
If you are using an older RHEL VM image, for example, RHEL 7.4 (image URN: RedHat:RHEL:7.4:7.4.2018010506), you will experience connectivity issues to RHUI due to a now-expired TLS/SSL client certificate. The error you see may look like "SSL peer rejected your certificate as expired" or "Error: Cannot retrieve repository metadata (repomd.xml) for repository: ... Please verify its path and try again". To overcome this problem, please update the RHUI client package on the VM using the following command: 2ff7e9595c
