While packaging Ktube Media Downloader for Ubuntu 16.04, I needed to make QDesktopServices::openUrl
work in the sandboxed environment. Qt uses xdg-open
, a script that tries to find the users default web browser, to open URLs on linux. This dosen’t work inside a snap since no browsers are installed.
The proper way to open URLs from a snap is by sending a DBus message. At first I thought I had to modify the application to achieve this, but I later realized that a “fake” xdg-open
script is enough. There’s a github repo called snapd-xdg-open that provides a working script.
Below is a snippet that you can add to your snapcraft.yaml
to install the fake script:
parts: snapd-xdg-open: source: https://github.com/ubuntu-core/snapd-xdg-open.git plugin: copy files: data/xdg-open: bin/xdg-open stage-packages: - dbus
