Opening unityhub:// URLs with Unity Hub on Linux

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 https://unix.stackexchange.com/questions/497146/create-a-custom-url-protocol-handler, I was able to get it working by adding a file called

~/.local/share/applications/unityhub-handler.desktop

with contents

Code (csharp):

1. [Desktop Entry]
2. Type=Application
3. Name=UnityHub Handler
4. Exec=~/Unity/UnityHub.AppImage %u
5. StartupNotify=false
6. 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 !!
