Opening unityhub:// URLs with Unity Hub on Linux

Unity Engine

Hi!

The download archives contain UnityHub URLs that us Linux users apparently have to use in order to install older Linux versions.

When I click on the links (leading to, i.e., unityhub://5.6.7f1/e80cc3114ac1), nothing happens.

I tried registering a custom protocol handler like this:

gconftool-2 -s /desktop/gnome/url-handlers/foo/command ‘/opt/UnityHub/UnityHub.AppImage %s’ --type String
gconftool-2 -s /desktop/gnome/url-handlers/foo/enabled --type Boolean true

I added a property called network.protocol-handler.expose.unityhub to my Firefox configuration, but it still complains “The address wasn’t understood”

I called UnityHub.AppImage with different variations of the URL:

./UnityHub.AppImage unityhub://5.6.7f1/e80cc3114ac1
./UnityHub.AppImage 5.6.7f1/e80cc3114ac1
./UnityHub.AppImage e80cc3114ac1

But this only brings UnityHub into the foreground.

./UnityHub.AppImage unityhub://5.6.7f1/e80cc3114ac1
That does work to start a unity hub link download, however, it looks like it’s not available for linux for download. You’ll need a direct download link from support.

Using this post as reference xdg - Create a custom URL Protocol Handler - Unix & Linux Stack Exchange, I was able to get it working by adding a file called ~/.local/share/applications/unityhub-handler.desktop with contents

[Desktop Entry]
Type=Application
Name=UnityHub Handler
Exec=~/Unity/UnityHub.AppImage %u
StartupNotify=false
MimeType=x-scheme-handler/unityhub;

(adjust the Exec line for wherever you’ve installed UnityHub), then running xdg-mime default unityhub-handler.desktop x-scheme-handler/unityhub.

just to add to this for flatpak installs you would use this command in terminal
flatpak run com.unity.UnityHub unityhub://2020.3.7f1/dd97f2c94397

xdg-mime default unityhub-handler.desktop x-scheme-handler/unityhub

Thank you very much !!
