Temporary workaround for Hub bug

The Hub is now installed on supported platforms via the corresponding package manager. Please see the documentation at https://docs.unity3d.com/hub/manual/InstallHub.html#install-hub-linux to install the Hub. You may want to clean up the files and edits from these steps prior to moving over to the package.

There is currently a bug in the Linux Hub where Hub links do not open the Hub. Additionally, searching for and launching the Hub in GNOME doesn't work.

Until the issue is fixed in the official build, here is a completely unofficial workaround that should get you going. Note that this is only tested on GNOME with no path configuration changes.

You can tell if you affected by this bug by checking for the existence of ~/.local/share/applications/appimagekit-unityhub.desktop. If this file does exist, you should be OK.

Otherwise, you can work around the issue by applying the following steps:

1) Create the file ~/.local/share/applications/appimagekit-unityhub.desktop with the following contents, substituting your correct home path and path of the UnityHub.AppImage file:

[Desktop Entry]
Name=Unity Hub
Comment=The Official Unity Hub
Exec="/home/SubstituteMe/.local/bin/UnityHub.AppImage" %U
Terminal=false
Type=Application
Icon=appimagekit-unityhub
MimeType=x-scheme-handler/unityhub;
Categories=Development;
X-Desktop-File-Install-Version=0.24
TryExec=/home/SubstituteMe/.local/bin/UnityHub.AppImage​

2) (Updated, see old step below if you have issues.) Run the following command to register the URL scheme with XDG: xdg-mime default appimagekit-unityhub.desktop x-scheme-handler/unityhub

2) Create or open the file ~/.local/share/applications/mimeinfo.cache. Add the following content. If the file already exists, leave out the first line:

[MIME Cache]
x-scheme-handler/unityhub=appimagekit-unityhub.desktop;​

You should now be able to open Hub links and search for it in GNOME.

 

Could you give an example about that, a link I could try? I don't seem to have this problem and the desktop file doesn't exist in my system. I'm using Linux Mint Xfce. Thanks.

 

Thanks for the suggestion, but unfortunately that didn't fix the issue in Pop_OS 20.10 (Unity 2020.1.10f1)

 

Works perfectly on Ubuntu 20.04. Really helpful workaround. Thanks for sharing!

 

Thanks. I get a white page in my browser when I click on this link; what should I get instead?

 

Yeah, I've used these buttons many times in the past.

The button for 2019.4.8.f1 you used as an example (not the link, the actual button on the archive page) actually works for me, once I've added the proper instructions to Firefox (I tend to forget to do that when a new version of the Hub is released. It wouldn't be a problem if I didn't change the name of UnityHub.Appimage into the full name of the new version though...):

​

Once this done, on clicking on the green UnityHub button, the hub opens and offers to install Unity:

​

Do I need to desktop file for anything else?

 

Oh, that's not much a bother.

Will this be fixed in a future version of the Hub?

 

@APSchmidt, the .desktop file if still necessary if you are in an GNOME environment where only apps with .desktop files show up in app searches.

Take Ubuntu for example. If you haven't added the Hub as a startup app, you will have to go to the CLI each time you want to start the Hub. If you have the .desktop file, you can press the Windows key and type "hub" and it will show in the search

 

Thanks for the input but, as I've already mentioned, I'm using Xfce, not Gnome. I have no problem at all starting the Hub.

 

It looks like a bug under Ubuntu, on Linux Mint 20 Cinnamon works fine.

 

Thanks, I was thinking it was a problem with my installation, I managed to fix it with the instructions.

I'm on Linux Mint 20 Cinnamon

 

Even though Unity Hub is integrated into my desktop, and set to handle unityhub links, opening it via the browser only opens Unity Hub - it doesn't actually open the version for install. Passing the unityhub link to the Hub Appimage on the command line works, but feels like very much not the intended experience.

Could this be related, or is it a separate bug?

 

Yes, it happens to me too. The only way, is clicking again and again on the Hub button on the web page until the installation starts... or try another day.

Probably a bug of some sort, either related to the Hub itself or the servers. Difficult to say.

 

@ettmetal, @APSchmidt

So clicking on a Hub link from the Unity Download Archive does not work after running both steps 1 and 2?

I tried this on my Linux Mint 20.1 install and didn't have a problem with the Hub links.

If you paste a specific link I can try, that would be helpful.

 

Unfortunately, it doesn't happen with every link; I remember having to try ten times in a row before the installation begins. I don't remember with version of Unity it was.

 

I know I'm not on a supported distro (dirty Arch/Plasma user here) but this worked perfectly for me

Since the version installed from the AUR installed the bins rather than the appimage I modified the Exec and TryExec lines to /opt/unityhub/unityhub-bin

Many thanks for the workaround

 

working! this should be stated in the docs tho
but how to add an icon? this gear icon is ugly lol

 

Please help! I'm having a trouble logging in into Unity. It pops up a dialog saying "You must install UnityHub to sign in and use unity services". I followed the steps and was expecting that this popup will go away, but it didn't. How can I let Unity know that UnityHub is already installed and let me log in? I'm using Ubuntu 20.04LTS. Thanks so much!

 

You need to launch Unity Hub to be able to start Unity.

https://docs.unity3d.com/Manual/GettingStartedUnityHub.html

 

Hello!
I am having this issue on Linux Mint 20.2 Cinnamon and the workaround doesn't work. Passing the link to the AppImage at CLI also doesn't work.

More specifically: I can't login, the redirection link just opens an empty page.

 

I managed to get this to work. A couple of tips:

• You need to create the file in #1 - yes, "Create" is the first word of the first instruction, but I somehow didn't read it
• Remember to put the correct path to the appimage file (probably you have to replace not only your username but the path to the bin file)
• You need to open the hub from the desktop entry (not via command line). In cinnamon launcher, if I created the .desktop file correctly, I could search for Unity Hub.
• If you have gotten your browser / xdg in a weird state from all the previous attempts:
  • Open the Hub
  • Click on the sign-in link
  • You will be directed to an empty page
  • Copy the URL
  • Open a private browsing window
  • Paste in the URL
  • Sign-in on the web
  • You will see an empty page
  • Go back to the Hub, cross your fingers, it should hopefully log in now
• I had to manually re-add my licenses to the new version (skip the buy flow after logging in and then manually activate)

 

Thanks for the advice! I just redid all the steps carefully from the first post and I realised that I stupidly believed "~/path/to/AppImage" would mean the same as "/home/MyUsername/path/to/AppImage". Which is completely false because I presume my user isn't the one handling xdg? So now that I properly substituted the paths it works! Thanks again for making me try the steps again, haha!

 

Hello, I know this is an old thread revived recently but I was having the same issue in Xubuntu 20.04 using Firefox or Chromium and wanted to say that this guide helped to solve my issue.

Thanks!

 

Hi, just wanted to say thanks for this. I was stuck with UnityHub not logging in just opening a blank webpage. After following this all is working. One thing to note, the .desktop lines have the AppImage name as UnityHub.AppImage - The one I download was UnityHubBeta.AppImage, but works as expected after getting the paths and the filename correct.

 

Thanks a bunch! Got it to work with Pop!_OS 21.04.

hadrosaurunity and Bodsda's comments were both super helpful. Thanks!

 

No, I use a script to launch my projects from terminal by just typing `unity project_name`

To launch a project, you just need to run the Unity binary and pass the path to your project's root using '-projectPath', no need to launch the hub first.
Ex: /home/my_user/unity/2020.3.20f1/Editor/Unity -projectPath /path/to/my/unity/project

 

No longer, you need to start Unity through the Hub nowadays.

 

This issue is still present on UnityHubBeta.AppImage V 3.0.0-beta6 in Debian 11 x64amd - KDE Plasma

Tested on Firefox-ESR Firefov-Dev-Ed Konqurer and Chromium. All same result with no changes to behavior. But this now affects Hub Logins outright. Since switching from embedded login dialog over to browser oauth.

OP's solution worked with minor correction to the appImage name intended. (UnityHub > UnityHubBeta)
Step 2 was not necessary in my case. It just worked.

EDIT. The re-release of the Linux UnityHub 3.0.0-beta6 will resolve this issue (Archive, not the solo AppImage) Follow included install instructions and it'll place the *.desktop file for you now.

Witch version of unity hub should i use as mine freezes when i try to search for licence
I'm a little confused how licence should be able to get and set is there any complete guide that would guide me through the process.

Seeing that xfce has less bug problems I might just switch to manjaro xfce also seeing arch doesn't have problems (people's posts)

 

ok found the witch hub to install

https://unity.com/download

and just follow the steps on the read me file

works fine

on Xubuntu

 

Sorry but this fix is not working on Ubuntu 18.04 - It works on Ubuntu 20.04. I tried with both Chrome and Firefox. I dont see the Pop-Up when I click on the Green Unity Hub button for a specific Unity version.

@Tautvydas-Zilys @KevinWelton Any suggestions on what I could do?

 

I can't get the desktop shortcut working! I have followed what it says in post 1.

 

if you are on archlinux or manjaro which this 2 aren't supported BUT in AUR repository there's UnityHUB it works flawless

 

I will update this post. The Hub should now be installed via the package manager. The package will configure the Hub link making the workaround unnecessary.
