This seems to be broken again. Some update since 11 March 2026 to the evening of 12 March 2026 has broken /usr/share/doc/radicale/examples/apache2-vhost.conf . At least, I haven't been fiddling with any of the config files.
I know Apache (mostly) works because it lets me connect to https://localhost/radicale , which I've been using for the last 3.5 years until it started throwing 503 errors. I know Radicale is (technically) working because I can run its service and connect to 127.0.0.1:5232. Unfortunately, that's not good enough because I cannot log in to the latter because it's expecting remote_user credentials and any other authentication scheme fails. On the Apache side, every attempt to connect is getting this error message: No such file or directory: AH02454: uwsgi: attempt to connect to Unix domain socket /run/uwsgi/app/radicale/socket (radicale:0) failed I have python3-radicale & radicale installed, with all their dependencies, recommendations and suggestions. The fault is probably between apache and uwsgi. But since the stock radicale configuration files and examples aren't working, I wonder whether they need tweaking... again.
