+This is macOS 11.2.1 (Big Sur), installed via `brew install git-annex`. I've tried the same behaviour on 2 separate macs, same error both times. It seems like the switching in the web UI is a bit tricky. I've also tried a few browsers (Safari, Chrome) and my dev browser without any ad blocking. It seems like there's an HTTP request to `/config/repository/switchto/...` which returns a 500.

+## Thanks
+
+I've just started the missing of moving from nextcloud to git-annex after the second random deletion of data by nextcloud. I'm deeply grateful to the authors for giving me the confidence of git to manage my files. Wonderful.
