PlayOnLinux on Ubuntu Server?

Question

I can't find the system requirements for PlayOnLinux, but all I got from their website is how to install on Ubuntu 20.04 - is it even possible to install it on Ubuntu 20.04 Server?

I tried to install PlayOnLinux_4.3.4 .deb (link below) on Ubuntu Server 20.04 and I got the message below - which make me think PlayOnLinux needs the GUI of Ubuntu Desktop:

"xrdb: Can't open display '' Unable to access the X Display, is $DISPLAY set properly?

https://www.playonlinux.com/en/download.html ** PlayOnLinux installer for Ubuntu

I downloaded: > PlayOnLinux_4.3.4.deb Then installed as below:

sudo dpkg -i playonlinux_4.3.4.deb

Questions:

Is PlayOnLinux compatible with Ubuntu Server? If so, how do I fix the error above
Running my VPS with Ubuntu Desktop doesn't look good, do I have any alternatives?
I just need to run a MSDOS app, how do I get the command prompt in PlayOnLnx?

Many thanks

How about you tell us specifically what you actually want to achieve instead of how to fix something you tried that didn't work? What DOS app, and why? — Organic Marble, Dec 30 '22 at 18:01
You are correct, you need a GUI. However if a DOS app is all you need, can't you try DOSBox instead? — Matias N Goldberg, Dec 30 '22 at 19:37
I've a console app that uses .NET libraries and if I run it with >Wine cmd.exe it doesn't work. So Matias thanks for confirming that POLnx needs a GUI. No, DOSBox doesn't work either, so I've installed Win 8 on a VM and it works. Thanks everyone. — Brian Tracy, Dec 31 '22 at 18:16
