Problem with installation icingadb-redis

When i can try to install this package: icingadb-redis in my machine (Ubuntu Server latest version) I received this message: Unable to locate package icingadb-redis.

Also I tried with apt update but nothing, the problem persist

Hi @Samuele28

I think it’s in the Icinga repository and did you add it?
What’s the output of apt update?

Having the same issue. Here is the output of the apt install icingadb-redis:
Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
E: Unable to locate package icingadb-redis

Results from apt update:

Working on a demo install of Icinga2 for work and this is holding it up now.

there are no packages for 23.10 since it is not officially supported as an icinga server disto

here is the support matrix which indicates to use a LTS distro
