Icinga 2 Ubuntu Installation Guide is broken about icinga2

[oxzi]

Thanks for trying out Icinga 2 and creating an issue.

I took the liberty of editing your entry so that the shell output is displayed as a code block.

icinga@icinga:~/Downloads$ sudo wget -O - https://packages.icinga.com/icinga.key | gpg --dearmor -o /usr/share/keyrings/icinga-archive-keyring.gpg
[...]
gpg: can't create '/usr/share/keyrings/icinga-archive-keyring.gpg': Permission denied

You are using sudo for wget -O - […] which then downloads the key as the root user to put it on the stdout. However, your following gpg command is then run as your local icinga user again. Thus, you also need to prefix this command with sudo, as well as every following commands requiring evaluated privileges.

As the linked documentation expects the root user to enter the command, you could also switch to a root shell for installation as most commands are requiring root permissions anyway.

It more broken that that.

I've tried twice with clean installs of Lubuntu and even the key is broken from my last try, splitting up the key settings.

Err:8 https://packages.icinga.com/ubuntu icinga-focal InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C6E319C334410682

Could you please paste a full terminal output of everything you did to get to this error? Are you using the root user?

I split this command wget -O - https://packages.icinga.com/icinga.key | gpg --dearmor -o /usr/share/keyrings/icinga-archive-keyring.gpg

wget -O - https://packages.icinga.com/icinga.key
sudo gpg --dearmor -o /usr/share/keyrings/icinga-archive-keyring.gpg

I've rebuild this VM a few time to try to get this app to install on Lubuntu 22.04.2 LTS but it always seems to fail.

Pardon, but I am simply not able to reproduce where your installation fails. As you haven't posted a full log, it is hard for me to follow your steps.

Please retry with using the root user for everything.

Just to make sure, I tried the installation within a container which should be very similar to your setup:
