Opening Links from Document Viewer
Hi! I just received the error "Failed to execute child process "/usr/bin/vivaldi-stable" (Permission denied)" when I tried to open a link in Document Viewer in Ubuntu 16.04. I tried the link just in the browser itself – it works fine – but I'm wondering if it's having issues using Vivaldi to open pages as my default browser. I'm not sure that's the reason, though; that's just a guess.
Let me know if you have any explanations and/or fixes.
On my system, /usr/bin/vivaldi-stable is a link to /opt/vivaldi/vivaldi which is the real vivaldi startup script.
However, /usr/bin/vivaldi is a link to /etc/alternatives/vivaldi which is a link to /usr/bin/vivaldi-stable which (as above) is a link to /opt/vivaldi/vivaldi!
That's complicated, but it would suggest that if you can start vivaldi from your GUI (however you do it) you should be able to start it via Document Viewer.
All I can suggest is that you check that the files and links exist and have the correct permissions.
