meatsack · #1 26th June 2009, 05:42 AM

Problem: Yum cannot seem to reach any repository. Returned error is as follows:

Quote:

[root@enterprise dyland]# yum update
Loaded plugins: fastestmirror, presto, protectbase, refresh-packagekit
Loading mirror speeds from cached hostfile
Error: Cannot retrieve metalink for repository: fedora. Please verify its path and try again

Additional information: Attempting to reach download.fedoraproject.org or mirror.fedoraproject.org via lynx or firefox returns a "unable to connect to remote host" error.

Diagnostic 1:

Both download and mirror respond to ping.

Both firefox and lynx can reach these sites via ip. URL address still fails. This indicates DNS issue.

Diagnostic 2: Confirm dns settings are correct

Correct DNS servers for my ISP. Confirm their reachability and return of correct data:

Confirmed correct dns server addresses and they are functioning.

Diagnostic 3: Statically assigned url -> ip pairs in the hosts file and then ran yum update

Quote:

[root@enterprise yum.repos.d]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

209.132.176.120 download.fedoraproject.org
209.132.176.120 mirrors.fedoraproject.org

192.150.18.37 linuxdownload.adobe.com
193.28.235.40 rpm.livna.org

193.28.235.60 download1.rpmfusion.org
213.129.242.84 mirrors.rpmfusion.org

Yum updates now work

Conclusion: Something is interfering with fedora 11 functions from accessing dns in the protocol stack (my best guest).

Note: Firefox was fixed by going to about:config and changing network.dns.disableIPv6 = TRUE

Can anyone who has this same problem with a FRESH install of Fedora 11 please confirm that static assignments in the hosts file fixes the issue.

This link addresses the issue:

http://digitizor.com/2009/06/17/how-...-in-fedora-11/

HOWEVER . . .

I still believe the root issue is a DNS problem.

Going to try to open a bug on this

Bug 508423

CiaW · #5 27th June 2009, 10:13 PM

I got the same error message on the netinstall cd -- fwiw. I didn't know of any way to check dns issues from there, but I did try different mirror addresses via the 'edit' option and got the same error.

meatsack · #6 30th June 2009, 05:44 PM

Ok, please consider the static hosts file entries in my above post a work around.

The root cause of the problem has been determined and a fix is in place.

Please consult bugzilla for the fix

Iam having the same issue on a system I installed and want to chime in with some info.

I used the fedora 11 cd for x86-64 for install. Same disk as my home system that gets its connection from comcast and I have no problems what so ever. I did an update (yum -y update) and rebooted and still no issues. Everything runs fine on my home system.

Now, On system2 I built using gigabyte MB/AMD dual core at another location also in comcast I had the same outcome. No problems what so ever. Just like my home system.

Then--- I installed an exact same system as system2 but gets its connection from AT&T DSL (yahoo, Ill call it system3). System3 is connected to a motorola dsl box (model 2210-02) and I did NOT do any updating. What I found was I can surf the net ok with firefox but I cannot do any yum updates. Yum errors out with the mentioned error message. I have tried to add fedora to the hosts file and doing a yum update but I get alot of errors for sites being busy. So, Its not really a fix.

/etc/nsswitch.conf file contains the line: hosts: files dns

This is the same line that is in the nsswitch.conf file of the other boxes that work fine.

Therefore, I think its something related to how a DSL connection (pppoe ? ) is handled as any boxes connected to something else like comcast have no problem. As far as I can figure the dsl modem handles pppoe internally so there is no reason that would be a problem.

In reading the above posts I didnt see any mention of what type of connection the boxes where on that are having this issue. Might it be a DSL connection issue within fedora??

Love to hear from anyone with their point of view on this and any real fixes possible.

I'm in Canada and am using as Shaw Cable cable modem. Its connected to a linksys wireless router and I use wireless primary.

As far as I can tell, all dns values are being passed correctly and nslookup / digs show proper resolution . . .

I wonder if anyone out there is on the AT&T DSL sbc yahoo service and having any problems?

Im thinking its a proxy problem maybe for me. I dont know. Browsing works fine with no proxy settings. Ping works but yum doesnt with the DNS error.

Same problem with a cable modem. Even tried the nss-dns patch but didn't fix it. Firefox, thunderbird etc, ok, yum isn't. F11 through update on F10.

coffee412 · #11 4th July 2009, 03:56 PM

Can I ask what service you have for internet?

Im thinking right now that the problem has something to do with proxy service maybe? My home system running F11 with updates runs fine tru comcast internet. I havent experienced this problem except for SBC/yahoo DSL for a customer of mine.

I am using a cablemodem. I have in the meantime solved the problem. I do not think it was dns resolution as I substituted the ip numbers for the names and was having the same problem. Eventually I manged to update the list of repos and I think that was it. I think it might have been a problem with the repo list following an upgrade from F10 to F11.

Hopefully that works in my case. Thanks for chiming in on it.

Happy Fourth of July

I think the error below is the same problem, am I right? If not, please say so, so that I can open a new thread to try and solve my own problem...

Code:

rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
Retrieving http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
curl: (6) Couldn't resolve host 'download1.rpmfusion.org'
error: skipping http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm - transfer failed

For convenience all the other rpmfusion urls removed as they give the same error.

The above is the error that Iam getting.

Can you ping your address in your link? Im not sure they are the same.
