I upgraded the system until I have to check “the safe rpms” a the surprise:
Can’t install tree package.
Repos not available i had to http://docs.nethserver.org/en/latest/subscription.html#removing-a-subscription and the system came back to live.
I haven’t see the benefits of the safe repositories. I know that is a long and heavy work for a FreeServer, but a client will be upset for this kind of failures. I’m not in a hurry, is the third problem of this week, ¿any body helps?
Once you complete the registration, can you attach the output of
yum repolist -v
Also
yum check-update
And
rpm -qf /etc/yum.repos.d/*[root@nethserver /]# yum repolist -v

Now is working 
(after the RE-subscription, of course) I saw librabbitq 08 for update not the last kernel. thanks @davidep for Your help.
I’m happy you solved.
a support specialist will be upset if the client is upset for this kind of failures 
Lesson learned: don’t be upset.
…and remi markuz ocsinventory… How many third parties repos did you install? Please consider to remove any additional package that comes from those repositories: problems are difficult to track and debug in a such environment! As the link above states:
The subscription provider may not accept support requests for the contents of custom repositories.
Okdoky, I need a SQLserver repositories for SQL-Server database That we have on work (just for check-backups on another server) OCS Inventory for machine info, mrmarkuz for OnlyOffice.
Now everything is back to normal way.
