Hi guys,
thanks for the great work. I am looking forward to Andy’s hands on training and as prerequisite I installed zabbix from mrmarkuz repo on a new nethserver, which worked flawlessly. 
I don’t see a possibility to switch the webinterface to german language though. Is there any additional package or configuration needed?
You may edit /usr/share/zabbix/include/locales.inc.php and edit line 57 to set “display” to true for German language:
'de_DE' => ['name' => _('German (de_DE)'), 'display' => true],
After browser refresh it should be available in the “User settings” dropdown. They hide it by default because it’s not fully translated.

Perfect. Thank you, that worked. 
Hi Markus
I’m helping a friend who has a NethServer running at a lawyers practice.
The NethServer has a Crostino Subscription running.
My friend wanted to update Zabbix and ran into issues…
I had a good look, and completly deinstalled Zabbix:
yum remove zabbix* nethserver-zabbix
I then also removed the PG database, removed the entries in the cnfiguration DB, cleared out the folders under /var/lib/nethserver/zabbix, /var/lib/zabbix, /etc/zabbix
Even rebooted the server.
Doing an installation it breaks with
Note: It’s looking for Zabbix 4x stuff on a fresh installation of Zabbix 5x - and failing!
This shouldn’t happen - even with a subscription (Repo conflict?).
It seems more a deps problem on something…
Any ideas?
Thanks
Andy
Did you already try with enabling the repos?
yum -y install --enablerepo=mrmarkuz,zabbix,zabbix-frontend nethserver-zabbix
Maybe it helps to clean yum before reinstalling?
yum clean all
Both tried…
I almost always automatically enable the repos with a -y…
Some habits die hard!
The console still has the command listed…
Just to discard it, check if there’s and older zabbix repo file.
Correct. Check the zabbix repo and the URLs it contains
Just install most recent zabbix release:
yum -y install https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
That is installed now…
However:
running the next step:
yum -y --enablerepo=mrmarkuz,zabbix,zabbix-frontend install nethserver-zabbix
gives me this:
The error seems to appear right after checking the deps…
Bingo!
That was the solution!
It’s installing the right versions right now!
I do love NethServer - especially the people on this Forum!
And It’s back up & running…
My 2 cents
Andy
Hi all,
What a marvellous forum this is.
A pro has a problem, another pro solves it within an hour.

And for No-Pros too. This is actually the even greater achievement, as it demands a lot more from the Pros.
Hi @mrmarkuz, I have the same problem Andy was faced with. I’m trying to find that script but have no luck. Could you please point me in the right direction?
Thanks
Nevermind, I found it
#!/bin/bash
systemctl stop zabbix-server
sudo -i -u postgres pg_dump zabbix > /tmp/pre-encoding-fix-backup.sql
sudo -i -u postgres psql -c "alter database zabbix rename to zabbix_pre_encoding_fix_backup"
sudo -i -u postgres psql -c "create database zabbix with encoding 'UNICODE' template=template0"
sudo -i -u postgres PGCLIENTENCODING=SQL_ASCII psql zabbix -f /tmp/pre-encoding-fix-backup.sql
systemctl start zabbix-server
And it works perfectly! Thanks
Does ist suffice to install from the repo for a fresh install or do I have to do these database things?
