yum/dnf update hangs at 99% for all repo sources

Initially, I thought this was an issue w/just Appstream, but even disabling this repo whenever I run `yum update` or `dnf update` it just hangs at 99% and never completes.

I've tried manually setting the base URL as suggested in other posts or using the commented-out default base URL, it does the same thing. I can't install anything or update, so it's fundamentally useless as an OS at this point.

Suggestions?

'Yum" in CentOS 8 now calls dnf, as I am led to believe.

Restore ALL the settings you changed back to what they were. Then try it again:

What's in the dnf log (/var/log/dnf.log) when this happens?

There are no errors in the dnf log.

You're saying yum works but dnf does not? That is very very weird since they are the same thing.

Code: Select all

[root@centos8 ~]# ls -la /usr/bin/{yum,dnf}
lrwxrwxrwx. 1 root root 5 Dec 19 15:43 /usr/bin/dnf -> dnf-3
lrwxrwxrwx. 1 root root 5 Dec 19 15:43 /usr/bin/yum -> dnf-3
But if yum works then use yum not dnf. They're the same program and work the same as they execute the same code.

No, I said neither work.
but even disabling this repo whenever I run `yum update` or `dnf update` it just hangs at 99% and never completes.

Umm - your closing line -
For the record, yum still works, dnf is the new package manager, though.
- and still no details to help us help you.

What details do you want?

It's a brand new install with literally no changes and it can't download from the mirror list. I have logs now from a new install, which again does exactly the same thing.

It's timing out reaching the mirror sites. I have tried manually curling some of them and the download starts, seems to get most of it downloaded then just hangs.

I have a CentOS 7 machine with a fresh install on the exact same network that works fine.

I was responding to the previous comment saying to use dnf. I was indicating the yum still works, in general, in CentOS 8.

Neither command successfully downloads an update. Both result it it hanging at 99%:


[root@localhost yum.repos.d]# yum update
CentOS-8 - AppStream 99% [========================================================================-] 917 kB/s | 7.0 MB 00:00 ETA

It just sits there for about 5 minutes and times out.

I've tried setting a number of baseurls including using the default instead of the mirror, no luck, same problem.

It seems to be complaining about the network connection/speed. I'd investigate that to start with.

Code: Select all

Timeout ...
Operation too slow. Less than 1000 bytes/sec transferred the last 30 seconds]
Yum = dnf ( the yum command runs dnf).
All times are UTC
