Bug Sign in link broken

Dromasin · Oct 13, 2021

Hey all. I'm currently trying to log into the unity hub for Linux, however, when I click the link it opens a blank webpage in my browser. I'm running on Ubuntu 20.04 (which I know is non-PORf but I've had no issues with it before!) Any help would be much appreciated.

dgs_stan · Oct 14, 2021

I am having exact same issue using Ubuntu 21.04
I noticed it you copy the link and open it in private browser it actually works sort of. it opens the sign in page you can sign it but after signing in it opens another blank page.
Copying the second blank link to non-private browser gives this:
{
"message" : "Conversation Not Found",
"code" : "132.191",
"details" : [ {
"field" : "cid",
"reason" : "Conversation not found"
} ]
}

PS Tried this on Chrome browser
Using Unity Hub 3.0.0.beta.5
Hope someone can have more info on this.

Thanks,
Stan

This is identical to the issue I'm having. Any support from the Unity team would be great. I'm having to work from a VM and it's not nearly as effective!

Hey guys,

I found a little work around that worked for me on Ubuntu 21.10:
Download Unity Hub 2.4.5
It opens and allow you to download latest version of Unity.
I was able to install Unity 2020 LTS
I am not sure where I found 2.4.5 but if you cant find it let me know I can upload it to google drive for you.

Hope this helps you guys too!

Howdy Thread!

Looks like this issue is resolved with the new re-release of 3.0.0-beta6. (Archive, not Appimage solo) It's an archive with the installation script and the appimage. Installing from the AppImage alone does not include the installation of the handler file to facilitate that login process. Hope it helps!

Crosspost of relevant thread with manual fix and details for those curious.

See reply no.9.
First I also got blank page in firefox, but after several login attempt I got a page said firefox can not understand the link and after a good time of search I got this post.

UnityHub 3.0 beta release is a disaster. Worst experience ever. Whole night was wasted on this problem.

As a former robotic industry software developer I really hate any software developer force you to update your staff, because "if every thing seems work then DO NOT UPDATE!!" is FOR A REASON.

And unityhub become one of them.
Back the day I was using windows, I forced unityhub to not update. After this unexpected-because I'm not joining UNITYHUB BETA- accident, now I'm going to FORCE unityhub to not update again.

I am having an issue running the INSTALL.sh installer script. Any pro tips on how to resolve this issue?

sh ./INSTALL.sh
This script will only run if the UnityHub.AppImage is at the same location as this script
This will wipe any existing Unity Hub installations, are you willing to proceed? [N|y]: ./INSTALL.sh: 11: read: arg count

It does not give me a chance to respond to the N|y question and instead crashes.

I am on Ubuntu 20.04.3 LTS

Same issue, I am on Ubuntu 21.04 LTS

Caused because UnityHub is not registered to handle unityhub:// links

I've found a workaround that works with latest Hub:
- Lauch the UnityHub AppImage, click Sign In
- Enter the credentials
- In the blank webpage you are redirected to, right-click -> show source. Copy the address starting with unityhub://
- close the UnityHub, open a terminal in the folder containing it, and start as a command :
./UnityHub.AppImage unityhub://<the-url-you-have-copied>

And Unity Hub should start properly with you being logged in!

A more direct way to solve this problem is to just register Unity Hub to handle unityhub links.

Just run this, then the sign-in dance between the Hub and the browser will work correctly:
xdg-mime default appimagekit-unityhub.desktop x-scheme-handler/unityhub

Howdy IronMAKERS.

Let's take a second and review OP's problem statement:
"I'm currently trying to log into the unity hub for Linux, however, when I click the link it opens a blank webpage in my browser. I'm running on Ubuntu 20.04"

So I'm assuming people asking for help here are on Linux (and they are running into the problem that the Unity Hub does not have the proper file type associations created for it, which is breaking the login process).

If this applies to you, then you run this by opening a terminal and copy pasting it in like so:

Code (CSharp):

oldman@oldman-desktop2 ~ $ xdg-mime default appimagekit-unityhub.desktop x-scheme-handler/unityhub

oldman@oldman-desktop2 ~ $

Then the next step is to try and login through the Unity Hub again - it should work now.

However, if you're on a different platform, then please create a new thread, as the problem/solution will probably be different.

This method doesn't seem to be working properly. After typing in "chmod +x UnityHub.AppImage," in my UnityHub folder, I followed this tutorial word for word. I've attached below an image of the results, I can't quite understand what they mean.

I was having the same problem, but just figured it out and got UnityHub to login in after 2-3 days of trying. There were two problems I had to overcome.

First, Unity's authentication method is sending a URL back to the browser that is supposed to communicate with the UnityHub app on your computer. However, it has the
unityhub
protocol and by default your operating system (Linux in my case) and your browser (Firefox) don't know how to deal with that protocol (as opposed to
http
for example). I discovered this by looking at the Firefox inspection console, which gave an error similar to:

Prevented navigation to “unityhub://login...” due to an unknown protocol.
Click to expand...

So the first thing to do is to associate the protocol with the Unity Hub app. The info from this link got me most of the way there.

1. Create a file unityhub.desktop containing
Code:
[Desktop Entry]
Name=Unity Hub
Exec=/path/to/UnityHub.AppImage %u
Type=Application
MimeType=x-scheme-handler/unityhub;2. Save it to ~/.local/share/applications/ directory

3. Open file ~/.config/mimeapps.list (create it if it doesn't exist)

4. Put in there
Code:
[Default Applications]
x-scheme-handler/unityhub=unityhub.desktopInstead of mimeapps.list, there may be <your_DE>-mimeapps.list (e.g. gnome-mimeapps.list), or even defaults.list. They are all the same.
Click to expand...

But you also need to make sure to reload the file in the OS before it becomes active:

Build cache database of MIME types handled by desktop files (may need sudo):
update-desktop-database
Click to expand...

I use KDE/Plasma, so nothing here is really Gnome specific. I don't know how this stuff works on Windows, but hopefully knowing what the problem is will help.

The second issue was that Firefox was preventing the authorization script from executing (until I authorized it). To fix this issue you have to open up the Web Developer Tools and open the console. You should see a warning line similar to this:

Loading failed for the <script> with source “moz-extension://[A_STRING_OF_DIGITS_AND_NUBMERS]/lib/SingleFile/single-file-hooks-frames.js”. authorize:1:1
Click to expand...

The text authorize should be a clickable link. Clicking on it will authorize the request and send the data back to the UnityHub app and successfully log you in.

Hope this helps

Andrew_dev_unity · May 12, 2023

My Path to get the unity launcher to work on Ubuntu 22.04 :

1. Download AppImage from https://forum.unity.com/threads/unity-hub-v2-0-0-release.677485/#post-4936106
2. Create unity account
3. Log in to unity Account in the browser
4. Start Appimage (by doing "chmod +x <name of the appimage>" and then "./<name of the appimage>"
5. Click login on Appimage window
6. A empty white window should open in your browser (for me the request for that xdg-open did not change anything)
7. On this empty site right click -> view page source
8. Copy the Link that starts with unityhub://
9. Go into Folder where your appimage is located (from step 4)
10. Open Terminal and type: ./UnityHub.AppImage unityhub://<the-url-you-have-copied>

This worked for me.

But https://forum.unity.com/threads/sign-in-link-broken.1182610/#post-8718240 seems to be a better more permanent solution. But I have not tested that.

EDIT: I don't know if step 3 is needed but I guess it cannot hurt
