Unity3D projects not opening from UnityHub

Hi all,

I use Unity3D for work and have been using UnityHub for project and installation management. Lately, since v2 of the Hub, I am unable to see my projects in the hub, nor am I able to add them via the UI. Opening my project with the Editor via the terminal results in the Hub being opened to select my project...

There is a thread on the Unity forums already, but Unity support is adamant that this is purely because of non-latin characters in the path... I opened an issue with the issue tracker, but they closed it and pointed me to the aforementioned forum thread. Since Arch is not officially supported, I do not foresee getting much more help from that end.

Here is a list of things that may help diagnose the issue:

Here is the log file from UnityHub: https://pastebin.com/naYMAC1b
The error message that pops up when following the log with is:

I have a laptop that I use for this as well, that is running Arch and I do not have this problem at all. I cannot see any differences between the two installations. I will update this post with that info when I turn on the laptop.

[EDIT]
Here is the information for the laptop:

Re: Unity3D projects not opening from UnityHub

Seems that the error messages in the info log were pertaining to the prefs file in ~/.local/share/unity3d being a directory instead of a file. I have corrected that, but the issue of not being able to add my projects remains.

The info log does not change when I try to add a new project, so I am now at a total loss.

For reference, my path is pure ASCII and does not contain any non-latin characters: /home/dabr/test

Opening the project with ~/Unity/Hub/Editor/2019.1.8f1/Editor/Unity -projectPath /home/dabr/test results in the following:

[0702/111653:ERROR:browser_main_loop.cc(161)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on.
[0702/111653:ERROR:sandbox_linux.cc(308)] InitializeSandbox() called with multiple threads in process gpu-process
[0702/111653:ERROR:browser_main_loop.cc(207)] Gtk: gtk_window_present_with_time: assertion 'GTK_IS_WINDOW (window)' failed
$ [Unity Package Manager (Upm)]
Parent process [4796] was terminated

In the UnityHub log I can see:

{"moduleName":"UnityIPCServer","level":"info","message":"[ 'client process has connected to /tmp/Unity-hubIPCService.sock!' ]","timestamp":"2019-07-02T09:16:53.086Z"}
{"moduleName":"HubIPCService","level":"info","message":"[ 'socket has disconnected: [object Object] , false!' ]","timestamp":"2019-07-02T09:17:03.474Z"}

I hope this information can shed some light on what is happening here.

Hi dude.
Did you manage to get unity3d installed and working with it?
I tried a lot of things, but today it seems unreal.
I can install an editor and a hub. The project even starts to come off, but falls ...
It is important for me to understand that at least one person was able to solve the problem or unity3d is not at all ready for arc ...
It is officially clear that only for ubuntu and centOs.
I found solutions ... But it was 2014

Re: Unity3D projects not opening from UnityHub

Another old topic. TiZed, instead of bumping all the old Unity topics, please start your own.

Closing.
