Initially, I was able to install Icinga2 on the client, but I was running into issues where it was unable to connect to the master host during the node wizard setup, so I decided to uninstall Icinga2 with the command below and removed all of the folders and the nagios user:
sudo apt remove icinga2 && apt autoremove
After a reboot, I attempted to install Icinga2 again, but I found that it was unable to create the nagios user and group and all of the other general folders were not installed i.e.:
How do I reinstall Icinga2 onto the client host with all of the common folders and nagios user and group? I’ve also tried
apt install -f icinga2, but that didn’t work.
