Can't create new calendar with fresh install on Ubuntu Server 22.04

[mazzekp]

Installed a fresh install on a new Ubuntu Server 22.04. The email part of the server works perfectly, but when I wanted to setup the calendar (the modoboa-installer was used with the Let's Encrypt certificate option so Radicale was installed with it), nothing happens when I login as the domain admin (adminuser@example.com), navigate to calendar, and then new calendar (create button on the pop-up window doesn't do anything).

Going to the mail.example.com/radicale/ displays the "Radicale works!" message. I've read a lot of message boards about this issue and couldn't find whether this was ever fixed or if there was a solution. Let me know if there are any questions or missing information. Thank you.

I too have the same problem. For info, I tried following advice in the Radicale documentation (https://radicale.org/v3.html) to create manually a collection /srv/radicale/collections/collection-root//calendar and created a file in the folder ".Radicale.props" with the following content {"tag": "VCALENDAR"}
{"tag": "VADDRESSBOOK"}. I had installed SSL certificates signed by my own CA. When I logged in to my account (https://<server.domain.tld>/accounts/login) and navigated to calendar no calendar showed and the new calendar button still did not work. When I tried to connect to the server from a Thunderbird client to create a new calendar on the client I was able to connect using the url "https://<server.domain.tld>//calendar" and was prompted to provide the user password. I received, not unexpectedly, the message "could not find calendars at this location". I had hoped I might be able then to import data to the client calendar and sync the data to the server. All to no avail. So I am left, like mazzekp, concluding the issue is not resolved.

Hi, can set DEBUG to True in settings.py, restart uwsgi service and try again to check what the server is responding ?

@mwyngloddwr, I'm working on that, see #112 :)

18 months on and I've solved my problem. I had installed SSL certificate and key created by my own CA in /etc/ssl/certs & private. I tried again recently to create a calendar and received an error notification 'certificate verify failed: unable to get local issuer certificate' - this despite the fact my CA certificate was also in /etc/ssl/certs. I now realise it should have been in the directory 'certifi' of the site-packages file of my modoboa instance (/srv/modoboa/env/lib/python/site-packages) where there was a file cacert.pem. When, having made a copy of cacert.pem, I replaced it with my own CA certificate re-named to cacert.pem modoboa-radicale worked as I had originally expected.
