Kolab at Debian12

[ladas at seznam.cz]

Hi everybody,

I installed Kolab at Alma9 last week, but up to now It not work properly. Guam listener crash, Folders at settings menu are not displayed, ... So I decided to try Debian12.
It is funny story, because here I am not able even set repo to be possible to install Kolab. Is it really so broken?

Here is my kolab.source file:
Types: deb
URIs: https://mirror.apheleia-it.ch/repos/Kolab:/16
Suites: Debian_12.0
Components: all
Signed-By: /usr/local/share/keyrings/apheleia-keyring.pgp

I downloaded and convert keyring file by:
wget -O- https://mirror.apheleia-it.ch/repos/Kolab:/16/key.asc | gpg --dearmor --yes --output /usr/local/share/keyrings/apheleia-keyring.pgp

when I try to update repos I get message:
Hit:1 http://deb.debian.org/debian bookworm InRelease
Hit:2 http://security.debian.org/debian-security bookworm-security InRelease     
Hit:3 http://deb.debian.org/debian bookworm-updates InRelease                    
Ign:4 https://mirror.apheleia-it.ch/repos/Kolab:/16 Debian_12.0 InRelease        
Err:5 https://mirror.apheleia-it.ch/repos/Kolab:/16 Debian_12.0 Release

If I use old style apt source list, kolab.list:
deb [signed-by=/usr/local/share/keyrings/apheleia-keyring.pgp] https://mirror.apheleia-it.ch/repos/Kolab:/16/Debian_12.0/ ./

after repos update I get message:
Hit:1 http://security.debian.org/debian-security bookworm-security InRelease
Hit:2 http://deb.debian.org/debian bookworm InRelease
