Why should the repos download and not syncronise?
Code: Select all
# yum install firewall-config
CentOS-8 - AppStream 30 B/s | 38 B 00:01
CentOS-8 - Base 166 B/s | 38 B 00:00
CentOS-8 - Extras 167 B/s | 38 B 00:00
Failed to synchronize cache for repo 'AppStream', ignoring this repo.
Failed to synchronize cache for repo 'BaseOS', ignoring this repo.
Failed to synchronize cache for repo 'extras', ignoring this repo.
No match for argument: firewall-config
Error: Unable to find a match
The problem seems to exist for all
yum commands I've tried.

try to comment mirrorlist and uncomment baseurl in
/etc/yum.repos.d/CentOS-AppStream.repo
/etc/yum.repos.d/CentOS-Base.repo
/etc/yum.repos.d/CentOS-Extras.repo
(or wait - maybe not synchronised yet...)

it looks like the repos are still empty.. see the size... EPEL8 is 1.8MB... the first three have 38 bytes:
Code: Select all
centos8:~# dnf grouplist

CentOS-8 - Base 30 B/s | 38 B 00:01

What i did and seems working for the moment is, changing the baseurl to:
/etc/yum.repos.d/CentOS-AppStream.repo
baseurl=
http://mirror.centos.org/centos-8/8/App ... x86_64/os/
/etc/yum.repos.d/CentOS-Base.repo
baseurl=
http://mirror.centos.org/centos-8/8/BaseOS/x86_64/os/
/etc/yum.repos.d/CentOS-Extras.repo
baseurl=
http://mirror.centos.org/centos-8/8/extras/x86_64/os/
/etc/yum.repos.d/CentOS-centosplus.repo
baseurl=
http://mirror.centos.org/centos-8/8/cen ... x86_64/os/
/etc/yum.repos.d/CentOS-fasttrack.repo
baseurl=
http://mirror.centos.org/centos-8/8/fas ... x86_64/os/

It's working now. I must have just been a bit too eager!

just a hint that when you install CentOS the network isn't always configured from the get go and it can produce similar errors. Try to ping or nslookup a website like centos.org to see if you see the outside world. I had the same error message on my fresh installation of CentOS then enabled network and yum was good to go. You can search on internet how to enable network.

Good points, but in my case I tend to do a network install, so the network was good! My usual test is ping 8.8.8.8, which cuts out any DNS resolution problems for a first stab.
