I'm using Kubuntu 19.10 and I have a problem with xdg-open.
Every link that redirects to an application doesn't work. For example slack links: I am on their website, when the link of accessing a workspace appear I only get the popup: "Open xdg-open?" and then nothing happens.
Same thing for zoom video calls. I click the link that should redirect me from the browser to the zoom application, same pop-up and nothing happens.
How can I fix it? The only thing that looks correct is the browser, so if I run in my terminal: xdg-open www.google.com
it opens the window on my default browser
