Manual upgrade error message

NethServer Version: 7.4.1708 (Final)
Module: bash yum

When I run a (partial) upgrade from the command line with “yum update” after the update I get this message :

Traceback (most recent call last):

Should I worry or is it normal behaviour when upgrading from command line?

yum clean all and yum update should fix
nethserver-hosts and nethserver-dnsmasq needs to be updated together or they introduce a circular dependency, but the second one has been released a bit too late.
Here the correct versions:
# rpm -q nethserver-hosts nethserver-dnsmasq nethserver-hosts-1.2.2-1.ns7.noarch nethserver-dnsmasq-1.6.6-1.ns7.noarch


Are the latest updates safe? I got a lill hesitant to update since latest major update :angel:
And I saw some recent updates are just released yesterday.

they’re tested, they should


Indeed, they seem ok, I’ll try a reboot tomorrow morning, before office hours.
