I follow this tutorial about Kubernetes.
I got to the part, which guide me to run:
minikube service sa-frontend-lb(I used sudo to run it, because if I don't use sudo it ask me to use sudo).
I get those following errors:
Opening kubernetes service default/sa-frontend-lb in default browser...

/usr/bin/xdg-open: line 881: links: command not foundI installed chromium and xdg-utils, but neither works.
How can I enter to the service, to see that it works?
As one can see, it is attempting to launch a browser, but there are none installed that it recognizes, except for what I would guess is Chrome (since one can see that "chromium" did not work out), and as the message indicates, it doesn't tolerate running as root.
In that case, what you want is actually:
minikube service --url sa-frontend-lbwhich causes minikube to print the URL rather than attempting to use xdg-open to launch a browser.
