DNF via ipv4 fails

Rocky Linux Help & Support
1

Hi,

today I did a new install of RL9.4, but thereafter an update via dnf failed wit “connecting refused”. Trying curl instead, to access ‘https://mirrors.rockylinux.org…’ showed me, that obviously ipv4 is not accessible. I tried an update on another machine, same result. Then I went over to IT department, and they told me, that ipv6 is not supported in the network of my machines. However, not long ago (mid December I guess) everything worked. I verified that in the network of the IT department, where ipv6 is supported, the update finished regularly. Now I am wondering, if something changed with deployment of repos via ipv4 or if I have to consider another problem? Currently I am a bit lost, the IT department will provide me a VLAN with ipv6 support, but I assume, that dnf should also work with ipv4, don’t? Please, can anyone point me into the right direction?

Kind Regards

Hello @hazel,

To my knowledge, dnf should work with either IPv4 or IPv6. It works on my machine with only IPv4. I’m running Rocky Linux 9.5.

Can you use curl on this machine? If so, what is the publicly routable IP address reported from:

curl ifconfig.me

Hi, thanks! Unfortunately I will have to wait until tomorrow, since I’m out of office now, but I will definitely check!

OK, if it reports only an IPv6 address, then you need to go back to your IT department and yell! :slight_smile: If it shows and IPv4 address, then try changing the repository mirrors you are using. You can even temporarily set them to the baseurl in /etc/yum.repos.d/rocky.repo research the repositories you have enabled as you may need to temporarily change this on all of your enabled (Rocky labeled) repos.

Good luck!

P.S., or choose another mirror location.

Good morning!

I tried curl ifconfig.me, and it returned a valid IPv4 address. I tried dnf check-update --refresh again this morning, and now it worked :blush: … maybe a temporary unavailability!? I’m not sure, but I will keep having an eye on it.

I will close this issue, thanks a lot!
