For the fourth time, I'm 100% aware that yum = dnf. Let's make sure that's understood. If you'd like to explain it again just to be sure, go ahead.

The network connection speed is fine. During the download, it showed a speed of 3-5 MB/s; a test of the bandwidth was around 4.

Are you behind a web proxy of some sort? Perhaps your ISP uses one without you knowing?

Can you use e.g curl http://mirror.centos.org/centos/8/AppSt ... es.yaml.gz -o to retrieve the file it's complaining about?
CentOS 6 will die in November 2020 - migrate sooner rather than later!

I did try curling it; the behavior is similar. It seems to successfully download most of the file then just hangs an eventually times out.

We've found this was a Cisco FirePower rule blocking this erroneously. Thanks for looking anyway.

Would you mind posting which rule it is. I am having the same issue and have Firepower firewalls.

Thank you

Just ran into this today as well. It's a result of the following bug: https://quickview.cloudapps.cisco.com/q ... CSCva10734

Thank you for linking that!

I've got a test system that suddenly 2 months ago wasn't able to receive updates. I thought it was a transient problem, but then I powered it up yesterday and it STILL couldn't. I exhausted everything I could think of locally with dnf and finally wiped the system and started fresh thinking there must've been something and it STILL wouldn't work.

Turns out it was the Cisco bug linked above. CentOS-8 - AppStream was hanging at 99% every time.

Strangely CentOS 7 and Fedora 32 machines on the same network worked fine through that period, but now they're failing too.

EDIT: elrepo is the only one hanging on CentOS 7, Fedora it's the repo for some proprietary software.
