Software Center Empty

ok, so I’d apologize, shouldn’t I?

BTW, please remember another thing: here there are people coming from all the world, not native english speakers… and all we are just reading black words on a white background… they have no “sound” and a reader can misunderstand the meaning

in any case, sorry for the misunderstanding

Here Error YumRepo Error: we found a problem with ipv6.
Could you try to disable ipv6?

sysctl -w net.ipv6.conf.default.disable_ipv6=1
sysctl -w net.ipv6.conf.all.disable_ipv6=1

Adam · November 12, 2015, 3:46pm

I ran those two commands and rebooted. Still seeing the same errors when running any yum commands.

I ran ifconfig and ipv6 addresses are still listed. Is that normal?

filippo_carletti · November 12, 2015, 3:48pm

Please, don’t reboot after running those commands.

Adam · November 12, 2015, 3:50pm

LOL! Oops! OK. ifconfig looks as expected without rebooting. Still seeing the same errors though.

filippo_carletti · November 12, 2015, 3:53pm

In the meantime I did check again that ipv6 is working as expected on mirrorlist.nethserver.org.
Could you please run the following curl command?

curl -v -L 'http://mirrorlist.nethserver.org/6.7/nethserver?release=6&repo=updates&arch=x86_64'

Here’s my output

Looking again at repolist output, you may have problems reaching centos mirror, not nethserver mirrors.

I agree… but I can ping mirror.centos.org just fine from the server.

Adam · November 12, 2015, 4:03pm

I hard coded the distro version, release and arch in /etc/yum.repos.d/NethServer.repo for the two repos that are having problems and I’m no longer seeing errors.

New:

[centos-base]
name=CentOS-$releasever Base
mirrorlist=http://mirrorlist.nethserver.org/6.7/centos?release=6&repo=os&arch=x86_64
baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
enabled=1
enablegroups=0

[centos-updates]
name=CentOS-$releasever Updates
mirrorlist=http://mirrorlist.nethserver.org/6.7/centos?release=6&repo=updates&arch=x86_64
baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
enabled=1
enablegroups=0

Old:

[centos-base]
name=CentOS-$releasever Base
mirrorlist=http://mirrorlist.nethserver.org/$distroversion/centos?release=$releasever&repo=os&arch=$basearch
baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
enabled=1
enablegroups=0

[centos-updates]
name=CentOS-$releasever Updates
mirrorlist=http://mirrorlist.nethserver.org/$distroversion/centos?release=$releasever&repo=updates&arch=$basearch
baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
enabled=1
enablegroups=0

So why would it not pull these values correctly just for these two repositories?

filippo_carletti · November 12, 2015, 4:14pm

I reproduced the problem. It seems that mirrorlist.centos.org has problems with ipv6.
See using ipv6:

# curl -L 'http://mirrorlist.centos.org/?release=6.7&arch=x86_64&repo=updates'
Invalid release

Forcing ipv4:

# curl -4 -L 'http://mirrorlist.centos.org/?release=6.7&arch=x86_64&repo=updates'
http://mirror.cov.ukservers.com/centos/6.7/updates/x86_64/
http://mirror.ukhost4u.com/centos/6.7/updates/x86_64/

Adam · November 12, 2015, 4:28pm

I see the same results you posted, but I don’t see how it’s related. Did you see the post above? For some reason it’s not resolving the $distoversion, $releasever, or $basearch variables. I didn’t try hard coding them individually… hmmm…

Adam · November 12, 2015, 4:36pm

OK. I did more testing and found that disabling IPv6 is required, even with the variables hard coded for distro version, release & architecture. Then tried changing from hard coded values back to the variables and everything is still working… wtf? lol

Maybe I needed to run yum clear all again after disabling ipv6?

I added the two lines @filippo_carletti mentioned to /etc/sysctl.conf and rebooted. Confirmed that everything is still working.

davidep · November 12, 2015, 6:00pm

This issue already came out in the past. We’ll left it behind when we stop asking the minor version to mirrorlist.centos.org (release=6.7 should be release=6). Their servers behave differently for ipv4 and ipv6.

filippo_carletti · November 12, 2015, 6:04pm

Yes @davidep, I’ve a plan to switch to relver=6 soon (you know, coffee machine chit-chat).
Meanwhile, I’m trying to understand if centos team is keen on considering a bug they server behaving differently over different protocols.

davidep · November 12, 2015, 6:10pm

I’ve read about this issue on their forums since years, I don’t think they’ll fix it soon

Adam · November 16, 2015, 6:01pm

Just to keep everyone updated, I installed another NS instance at a customer’s site today and had this same problem again. I ran the two commands Filippo mentioned and then the software center worked. Rebooted and it continued working… so there was no need to mess with repos or any of that mess. Not sure why it is happening in the first place or why it was so much easier to resolve this time.
