Hi, I have some additional information to share:
- Initially (see below), when I entered my login information into gnome-online-accounts, nothing was displayed in Calendar or Evolution. - For some reason, Calendar and Evolution now display the list of my calendars and address book; but they can't connect to their contents. Here are the error messages from Evolution: Adressebook: Impossible de se connecter au carnet d’adresses « CardDAV : Sans nom » Échec avec l’erreur HTTP 405 : Method Not Allowed Calendars: Impossible de se connecter à l’agenda « Sur le Web : Next_Ponctuel » Bad Request Impossible de se connecter à « chris...@posteo.net@nl.tab.digital » Erreur de résolution de « posteo....@nl.tab.digital » : Nom ou service inconnu - Note that : -> Connecting to my NextCloud account works fine from Files, which accesses and displays documents saved on my Nexcloud space. -> Before this last guix installation, everything worked fine with Evolution or Calendar. - among the things I've tried so far: separately (re)installing evolution-data-server and gnome-online- accounts. run guix pull then guix package -u and sudo guix system reconfigure Nothing changes I hope that these additional hints will help someone to find a solution for this problem.
