Does not start in Linux Mint

There are several machines running Linux Mint 18.3 Cinnamon x64 (core 4.10.0.38-generic). Configuration:
1) GIGABYTE GA-F2A68HM-S1 Motherboard;
2) AMD Athlon x4 840 Processor;
3) SSD PNY 120 Gb;
4) RAM 4-8 GB;
5) video Cards are different, quite old, such as GeForce GT220, Radeon X550, GeForce 7600GS, GeForce 9500GT, etc.
Install The Unity Hub. Everything is OK.
I log in, too, everything is OK.
I install the Unity version, also OK. And I tried to put different versions - both 2019 and 2018 - no difference.

Then I create a new test project (I also tried different ones). The project appears in the folder.

But I can't launch any of the new projects in any version of Unity or on any machine. Always gets an error:




According to the error text, the project is supposedly created in a different version, but the project is new, created just in the newly installed Unity. Clicking on any button closes the error window and closes the Hub, nothing else happens, Unity does not start. What can I do?

 

Linux Mint is like a twin brother to Ubuntu, but less bloated. The Linux mint version you're using has to be the same versions that Unity 3D is supporting. Linux Mint 19 is based in Ubuntu 18.04

Just out of curiosity, why do you support Centos? Is it popular on the server side for the stability of RHEL, but free?

 

Many Pro 3D software in Linux, video editors, compositors, etc Support RHEL 7 = Centos 7. I guess it is because the Long Term Support, and Red Hat solves a lot problems in the Linux Community. Centos can take those solutions for free, and I moved to Centos 7. It's quite fast as Fedora 32.

 

As far asI know CentOS is used a lot in the cinema industry, VFX...

 

I am using Linux Mint 20 and the Unity 2019 LTS and 2020.1 and 2020.2 works fine at the moment.
