PPA upgrade to 11.5.0 fails on updating Service Node with error: Unable to detect the fully qualified domain name of the host.


Hostname of Service Node is not fully qualified domain name or does not resolve.


  1. login to Service Node where issue occupied and check hostname. It should be fully qualified domain name like below:

    [root@servicenode ~]# hostname -f
    [root@servicenode ~]# cat /etc/hosts
    123.345.23.678  servicenode.domain.tld servicenode
