if you are asking for a final repository for Kopano One…
Ah yes apologies. I only recently starting using Kopano so still a bit confused about what everything is called. From what I understand there is no more Kopano One but there is Kopano Groupware.
Final repositories for Debian 11 Bullseye are available in the supported tree and therefor only available with a valid subscription.
Thanks also for claritying. I thought that would be the case, because when I looked for files here:
I only found these:Debian 10 Ubuntu 18.04 and Ubuntu 20.04 RHEL 8
So far unfortunately we only have one client that had typical shared hosting IMAP email and we were about to loose them to due to lack of calendar sharing when someone suggested Kopano open-source. So we managed to put together an Ubuntu 20.04 installation using public information on the internet. The client has practically no budget.
