Hello! I've got a Radicale service running on a Guix host that has Let's Encrypt certificates issued. There are no problems connecting to it with Icedove, or DAVx5.
Unfortunately Evolution, or its accompanying evolution-data-server fails to sync the Calendars whenever it is launched outside of Gnome's desktop environment. The error it throws are: --8<---------------cut here---------------start------------->8--- Failed to connect calendar “CalDAV : calendar” TLS support is not available --8<---------------cut here---------------end--------------->8--- Gnome-calendar obviously throws a very similar error: --8<---------------cut here---------------start------------->8--- (gnome-calendar:19192): GcalManager-WARNING **: 13:53:39.487: source_credentials_required_cb: Failed to authenticate 'calendar': TLS support is not available --8<---------------cut here---------------end--------------->8--- This is the same for calling Evolution inside Xfce, or i3. There is no problem while being inside Gnome. Though there is generally no problem with using Mail in Evolution -- in case someone wonders. Does anyone else maybe use Evolution outside of Gnome? And if so, do you use CalDAV calendars? I've compared my shell environments and manually copied exports that where set in Gnome's environment. Though that didn't help. Gnome-keyring is running, and accessible. I've also set up --8<---------------cut here---------------start------------->8--- (service gnome-keyring-service-type) --8<---------------cut here---------------start------------->8--- Even while inside Evolution it is possible to subscribe to CalDAV calendars and have possible subscriptions listed. So it is working somehow. I suspect that maybe a path to glib-networking or similar is missing. Kind regards Simon
