Bug [Ubuntu 22.04] Hub won't launch

Hello ,

After my fresh 22.04 install,

I tried installing UnityHub both via the AppImage & via the apt install (as explained here: https://docs.unity3d.com/hub/manual/InstallHub.html#install-hub-linux). None of those installation works. Best case scenario, I can accept the EULA but then nothing happen.

When I install the Hub via the AppImage and INSTAL.sh script, Hub wont launch and I have this error
I tried to apt install fuse, I no longer have this error but hub still won´t launch.

When I launch the Hub after the apt install unityhub method, Hub don´t launch. After a while I have this error:

Clicking the Report a bug button does nothing.

Any ideas ?

 

Also, I found those logs:
I'm currently trying to find a solution for the libssl thingy, but with no luck

 

FYI, I’ve managed to launch the Hub and login by compiling an older libssl version (since there’s only libssl3 on the new Ubuntu).
However, I can’t activate any license due to an other error with the ssl (that say to look in the enclosed exception, but unfortunately there's nothing).

 

Up!

 

same! up!!!!!

 

Ubuntu release thursday, I hope someone from Unity will check out the forum at some point...

I took the liberty to report a bug (Case 1421236).

 

Hello, I also had the same problem with the new version of Unity Hub.

The previous version was also not running on this new version of Ubuntu "22.04".

I managed to solve it by installing FUSE.

If it helps, follow below the commands for installation until the problem of the new version is solved.

Installing FUSE:

Open the terminal and type line by line.

sudo apt install fuse libfuse2
sudo modprobe fuse
sudo groupadd fuse

user="$(whoami)"
sudo usermod -a -G fuse $user


Download Unity Hub version 2.4.6

https://unity3d.com/get-unity/download


In the terminal, access the Downloads folder.

$ cd Downloads

type

$ chmod a+x UnityHub.AppImage


type

$ ./UnityHub.AppImage

and enjoy!

 

Thanks for this. Did you manage to activate your Unity license?

EDIT : I tried this on a VM and it works. However, it looks like we can't have updates for the Hub this way.

 

Yes, in this version of Unit Hub "2.4 "it's easy to activate the license, but in the new version I couldn't even activate it on Windows. This hub is rubbish. Some things shouldn't change.

 

I don´t know about on ubuntu 22.04 but on my fedora 36 install I had the same issue and I managed to get it working after installing these two packages:

sudo dnf install openssl1.1-1:1.1.1n-1.fc36.x86_64
sudo dnf install openssl-libs-1:3.0.2-3.fc36.x86_64

 

I managed to get it working on ubuntu 22.04 as well

I had to add this repository
echo "deb http://security.ubuntu.com/ubuntu impish-security main" | sudo tee /etc/apt/sources.list.d/impish-security.list
and install
sudo apt update
sudo apt-get install libssl1.1

after installing unityhub 3.1.2 works without any problems.

I have tried it on a clean install.

 

Thank you for the help.

It should have come from Unity but from what I see they don't care about Linux issues

 

Thanks you so much!!! I will post this solution on other threads this was the only solution that worked for me

 

Excellent thank you!

UBUNTU please update your install guide.

ubuntu 22.04
unityhub 3.1.2

 

Thanks! i had the same issue, now it works very well.

 

Thank you, you help me a lot

 

This worked for me as well! Thank you.

 

Thanks, this did it for me

 

This did the trick for me, kudos to you!

 

Wow this actually worked...ish Now to overcome the stupidity of failed to execute default browser. Thought it was some issue with snap apps but I replaced the snap version with a normal and still no dice...Unity sure knows how the layer the bs...

 

What a great job. It worked on my new ubuntu 22.04. I spent days trying to sort it out, but thanks to you, it finally worked

 

This did not work for me, as sudo apt update cannot find the location.

It seems I managed to get the hub working by manually installing the libssl1.1 from http://security.ubuntu.com/ubuntu/pool/main/o/openssl/, specifically libssl1.1_1.1.1f-1ubuntu2_amd64.deb.

 

Thank You So Much buddy....it perfectly works for me.

 

Just here to confirm this solution works (using Pop!_OS 22.04 - based on Ubuntu 22.04), without the need to adding a new source list.
However, you will need to restart your computer for this solution to be effective.

Anyhow, here are the command lines based on the solution provided by SudoPotato.

wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb

sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb

rm libssl1.1_1.1.1f-1ubuntu2_amd64.deb

PS: The last command line code removes the libssl file, to ensure that you do not have that unwanted file in that directory.

 

I read the thread, so it seems we need to have libssl1.1 working on the system to work with unity… But according to people at askubuntu it seems to be a very bad idea to mix libssl1.1 into Ubuntu 22.04… What would be great would be to use libssl3 in unity. Any plans to do that in the near future?

 

For those who still have problems, there is an official workaround with a list of steps, but as mentioned above require libssl1.1 which may not be ideal.

The workaround is mentioned in the OP of the following thread: https://forum.unity.com/threads/running-unity-on-ubuntu-22-04.1284083/

However, ideally, the Unity Hub should get patched so it supports libssl3 as well on Ubuntu 22.04 and later soon since as I mentioned in that thread that the workaround is not without consequences.

 

This worked for me, though if you are here by this date http://security.ubuntu.com/ubuntu impish-security main is no longer supported.

What is really important here is to install libssl1.1. You can do this by following the answer in this post of stackoverflow. https://stackoverflow.com/questions/73251468/e-package-libssl1-1-has-no-installation-candidate

If you get the warning that unity key is deprecated, the solution is here:
https://askubuntu.com/questions/1398344/apt-key-deprecation-warning-when-updating-system

 

Thank you very much for this solution. I finally get UnityHub working.

 

Again, this solution is just a workaround and might hinder the stability/security of your system.

I think the explanation given is not justified too well, still the harmlessness of the workaround is not justified any better. The consequences of installing libssl1.1 in the comments of the aforementionned askubuntu thread seem to bend on the "danger" side…

I'd take this workaround with caution (I'd rather not understand the consequence of what I am not doing than of what I've done…).

We might be getting close to a solution with libssl3 in unityhub3.4.0-β : it seems to launch succesfully in mint 21 !

 

Now unity itself won't work… The errors when trying to load an empty 2D project with freshly installed unity 2021.3.13f1

All compilers errors have to be fixed before you can enter playmode! :-(

 

Windows no longer supports older processors (such as Xeon). Unity, as we can see, ignores Linux.
Maximum motivation to study open-source programs like Godot. It's sad because time was spent learning Unity.

 

This issue is solved for me by installing unity hub beta. Check the forum here
