I am running a dnf update -y to prep the system for an upgrade to Rocky Linux.

When I run the dnf update the VM complains about packages that are required to be upgraded.

# dnf update
Last metadata expiration check: 2:37:02 ago on Thu 13 Jan 2022 11:47:08 AM CST.
Error:
Problem: cannot install both graphviz-2.40.1-43.el8.x86_64 and graphviz-2.40.1-40.el8.x86_64
- package graphviz-gd-2.40.1-40.el8.x86_64 requires graphviz = 2.40.1-40.el8, but none of the providers can be installed
- cannot install the best update candidate for package graphviz-2.40.1-40.el8.x86_64
- problem with installed package graphviz-gd-2.40.1-40.el8.x86_64
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

# dnf list installed | grep graph*
graphite2.x86_64 1.3.10-10.el8 @AppStream
graphviz.x86_64 2.40.1-40.el8 @AppStream
graphviz-gd.x86_64 2.40.1-40.el8 @PowerTools
python3-cryptography.x86_64 2.3-3.el8 @BaseOS

It seems as if graphviz and graphviz-gd don't match up.

I sent an email into support to see if I can get some help a little sooner but no response there either.

You're not trying to in-place upgrade CentOS 8 to Rocky Linux, correct? That wouldn't be supported, you would need to migrate instead of in-place upgrading as in-place upgrading isn't supported.

What is the output of these commands?

No I am not doing a direct upgrade I am running a migrate but that's not the problem I am having.

Here is the output requested.

What is the output of this command on your XI server?
I'm labbing this up to see if I'm able to replicate.

# rpm -qa | grep nagiosxi
nagiosxi-deps-el8-5.8.3-1.noarch

I found an article that said you can temporarily get around it by disabling the appstream repo but I want to know if your system is an RPM install of XI before I have you do that as I'm not sure of the impact.

I was not able to replicate it, I reverted to a snapshot that contained the graphviz-2.40.1-40 packages with the repos below enabled and it worked properly:
Do you have any custom dnf or yum protected packages?

Make sure it matches.
