Hi everyone!
Fresh installation of Zentyal 7.0 for using as Authoritative DNS Server, so only few modules installed: Network, Firewall, DNS, Logs.
After first configuration and first reboot, as many of you, I did not able to do updates, even if the available updates were shown in Dashboard / Software Management.
Following @mscfw hint https://forum.zentyal.org/index.php/topic,35174.msg114308.html#msg114308 (https://forum.zentyal.org/index.php/topic,35174.msg114308.html#msg114308), I did the updates (Core to 7.0.3 and other Zentyal software).
After reboot, same issue: Temporary failure in name resolution
Does anybody know how to fix this, or we must to wait an update from Zentyal?
I have the same configuration with Zentyal 6.2 and it works like a charm.
Kind regards,
Gabriel

Hi,
Do you get any error in the log files '/var/log/zentyal/zentyal.log' and '/var/log/syslog'?
When you lose the resolution, is the configuration file '/etc/resolv.conf' empty? If it is, did you try to restart the Network module? When the network module is restarted, it generate the content of the configuration file.
Also, I sent you a PM, please, as soon as you can read it.
Best regards, Daniel Joven.

Hi Daniel,
I sent you a PM.
The file '/etc/resolv.conf' is not empty.
Kind regards,
Gabriel

Hi Gabriel and thank you for your feedback,
I could reproduce the error and it seems to be related to DNSSEC. Please, add the following parameter below the option 'auth-nxdomain' in the stub '/usr/share/zentyal/stubs/dns/named.conf.options.mas':
dnssec-validation yes;
Then, restart the DNS module:
[code}
sudo zs dns restart
[/code]
Finally, check the DNS resolution.
Best regards, Daniel Joven.

Hi Daniel,
Sorry for my late feedback!
After I made the correction as you said, it works now.
Thank you for your help!
Kind regards,
Gabriel

Hello,
I had the same problem as Gabriel, and got it fixed after applying the stub fix.
Think this should be included as an official patch.

Hi Daniel,
Solved but not quite solved.
After I made some updates that appeared after I modified the file as you said, after restarted the system, the file was re-written without the modification and I was forced to insert the parameter again.
Will be an update to fix this issue?
Moreover, in Dashboard, at Core version, is written 7.0.3 (available).
If I check from Software Management, the messages said that no updates are available.
If I check from CLI, same messages.

Hi guys,
There is an open issue in Github related to this DNS resolution issue, you can check it out here:
* https://github.com/zentyal/zentyal/issues/2026
Solved but not quite solved.
After I made some updates that appeared after I modified the file as you said, after restarted the system, the file was re-written without the modification and I was forced to insert the parameter again.
If you set that configuration parameter in the stub located at '/usr/share/zentyal/stubs/dns' and you lost it after restarting the DNS module, it is because you have another stub located at '/etc/zentyal/stubs/dns', and this directory has more priority than the other.
Moreover, in Dashboard, at Core version, is written 7.0.3 (available).
If I check from Software Management, the messages said that no updates are available.
If I check from CLI, same messages.

Hi Daniel,
Hi guys,
There is an open issue in Github related to this DNS resolution issue, you can check it out here:
* https://github.com/zentyal/zentyal/issues/2026
The following commands do not work for me (even after rebooting the system):
sudo rm -v /var/cache/bind/managed-keys.bind*
sudo zs dns restart
---------------------------------------------------------------------------------------
If you set that configuration parameter in the stub located at '/usr/share/zentyal/stubs/dns' and you lost it after restarting the DNS module, it is because you have another stub located at '/etc/zentyal/stubs/dns', and this directory has more priority than the other.
/stubs/dns - these directories do not exist in my installation:
# cd /etc/zentyal/
# dir
core.conf firewall.conf logs.conf post-save pre-save
dns.conf hooks network.conf ppa.gpg zentyal.conf
#
----------------------------------------------------------------------
Moreover, in Dashboard, at Core version, is written 7.0.3 (available).
(available) disappeared. By the system itself, i think. ;D
---------------------------------------------------------------------
For now, I will stay with your solution.
Kind regards,
Gabriel
