Hi ! I’ve just transitioned to Linux from Windows and I’m trying to re-implement my workflow zotero->zotfile->mdnotes->obsidian. Unfortunately, I have the same problem as described by @alex_m above : nothing happens in Obsidian when i click on a link to Zotero in format [...](zotero://...). It does work though when I use the same link in the browser or LibreOffice Writer.
I work with ubuntu 20.04, I’ve downloaded Zotero from the deb file and Obsidian in the flatpak format.
As suggested by @argentum , it might be a setup problem. The outputs of xdg-mime query default x-scheme-handler/zotero and xdg-settings get default-url-scheme-handler zotero are both zotero.desktop and Zotero appears in the [Default Applications] section of ~/.config/mimeapp.list.
Any help welcome, thanks !
