Installing Nvidia drivers on CentOS 8

[TrevorH]

Check to see what files you have left in /etc/yum.repos.d that are not owned by any installed package: rpm -qf /etc/yum.repos.d/*.repo

I suspect you've removed the package but it's left .repo files behind that point to Stream repos.

Should I remove anything stream* ?

Right, so there is a centos-stream-repos package that also need to be replaced with the equivalent centos-linux-repos package.

Thanks for your help so far!
How can I go about this?

dnf shell:
> remove centos-stream-repos
> run

Problem: The operation would result in removing the following protected packages: setup
Nothing to do.

dnf info centos-linux-repos
Error: No matching Packages to list

[TrevorH]

You need to replace it with the centos-linux-repos package in the same way you did with the other one.

Since you are out in uncharted territory here, please make sure that this is not a mission critical system and that you have all your data backed up before you continue.

Ok.

sudo dnf shell:
> remove centos-stream-repos
> install ./centos-repos-8.2-2.2004.0.2.el8.x86_64.rpm
Error: Cannot add local packages, because transaction job already exists
> run

Nothing to do.
Complete!

Did you previously kill dnf in some way that it was interrupted? Are there any files in /tmp that look like they might be transactions?

[secetspaces]

Now that you say it: I did Ctrl+C out of dnf shell before I knew how to exit properly.
I think there weren't really any tasks pending and I can't seem to find something interesting in /tmp.

The above mentioned error persists after reboot.
(Error: Cannot add local packages, because transaction job already exists)

[TrevorH]

I have no idea how dnf tracks its transactions. Yum used to create a file in /tmp called something with "TX" or "tx" in its name. If not there then perhaps /var/tmp? Or maybe /var/cache/dnf?
