Hub app not launching after updating Ubuntu

I just updated Ubuntu from 18.04 to 18.10 and I can no longer open Unity Hub. I tried fixing it, but I can't find and delete all the installed files and then reinstall. I tried removing files from my folder:

1. home/.local/share/applications/Unity Hub
2. home/.local/share/unity3d
   
3. home/.config/UnityHub

And then running the AppImage again. I get the dialog asking me to integrate it with my system, I press yes, try to run it and nothing happens.

 

It turns out it was some kind of problem with permissions. I ran the AppImage with sudo and it worked. I didnt see any similar problems to mine, so I figured it would be a problem on my side. Now everything is working as expected. Thank you though

 

Hello, I have same problem.
I use unity hub on Mint 18.10 and all was good.
Next I setup Ubuntu 19.04 (it was clear install, not update).
I download UnityHub.appimage but it's start only with sudo.
I try version 1.6.0, 1.6.2 and today 2.0.0.
Without sudo, when you first start, there is a dialogue about integration in the system (you can agree or refuse, it does not matter) and nothing else.

 

I got same issue in 18.04 ubuntu.

I found a solution for running unityhub from command line.
cd ~/Unity/Hub/Editor/2019.2.0f1/Editor
./Unity

This will open Unity Hub

 

Same for me here; a fresh install of a 19.04 ubuntu. Only root can run UnityHub.appimage; and the install stops without messages.
[edit]It came from my internet connection. Now I can run Unity but only with root; standard user gives segfault[/edit]

[edit]Sum up for installation on 19.04 :
- sudo apt install libgconf-2-4
- get the UnityHub from https://forum.unity.com/threads/unity-hub-v-1-6-0-is-now-available.640792/
- run the UnityHub as root
- install Unity
- change rights on the following directory
- chown -R user:user ~/Unity/
- cd ~/.config
- sudo chown -R user:user unity3d/ Unity UnityHub/
- cd ~/.local/share
- sudo chown -R user:user unity3d
Now you can run Unity for the standard user with :
- ~/Unity/Hub/Editor/2019.2.0f1/Editor/Unity

I get error when trying to run a blank project; but with no label no description!!!

I installed 2018.4.5f1 it seems to work well (kart demo)
