I just installad Fedora 22 and DNF (yum's replacement) is performing terrible.

9 out of 10 request fails out of timeout, with random effect specifying IPv4 or not. The problem seems to be that DNF can't pick a proper mirror nad often pick a non-responding one, or a terribly slow one.

Feil: Error downloading packages:
Curl error (6): Couldn't resolve host name for https://mirrors.fedoraproject.org/metalink?repo=updates-released-f22&arch=x86_64 [Could not resolve host: mirrors.fedoraproject.org]

Also, I think IPv6 is caussing some trouble, so it has been deactivated on my system. Restarts dosn't change anything either...

(Before I found ask.fedoraproject.org I asked the same question on stackexhange first: http://serverfault.com/questions/7069... )

curl http://icanhaztrace.com may show up some issues. I too suspect your DNS provider sucks. It may be time to ditch them, or host your own dns cache.

I agree with the posting, dnf is much slower than yum. Further it often tries to connect to a high/random port on the mirror server, which our company firewall doesn't allow. I never had this problem with yum.

@polywogsys, I am quite new to Fedora. Haven't used an RPM tool since Mandrake's urpmi. But, dnf is always trying to connect in order to keep metadata fresh. Unless they are doing strict whitelisting, your company firewall is dumb. If they allow any <1024 to go through but do not allow any >9000, they are being lazy.

dnf has proxy options for such cases. man dnf.plugin.config-manager

So, you have already found the answer , right?

Updating to googles DNS Servers worked like a charm on the first try! Thank you! If you post an answer I will accept it, also if you have tips on public DNS it would be highly appreciated :)

If you don't know how to permanently change the DNS servers, via NetworkManager, have a look at this answer.

As for DNS service, I'm using OpenDNS(has nothing to do with OpenSource) for some time now and I have no problems.

There are many other fast ones to chose from too:

Symantec also offers free, basic DNS.

Thanks! I'm looking for some good DNS servers, It's a shame that my ISP is not up to the task :/

You could mix more them. The traditional maximum are 3 entries. So 1 from OpenDNS, 1 from Yandex, 1 from Google (;

NuuN ( 2015-07-20 14:53:46 +0000 )edit

Yup, Thinking I should go for OpenNIC as #1, and Google for #2 nd #3... (a little anonymity would be nice :) )

This is just a temporary issue which you are having,keep on repeating the command. Or , it may be that you have a poor internet connection.Also try

dnf clean all
dnf clean packages

keep on trying repeatedly.It may work
