I have already used the commands that the error itself suggests but the following appears

1° No ~ sudo su eduardo@Eduardo:~ apt install xorg-x11-utils
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

2° With ~$ sudou su

Dear Eduardo,

did you install and run an XServer on Windows as described in sections 1.2 and 3.1 of the guide you linked?

Cheers,
David

Yes Dávid,

I installed the 2 and I believe this must be disturbing something. But I tried to uninstall MobaX and the following message appears.

Dear Eduardo,

unfortunately, I can’t help you with this error. But, did you try restarting your PC before uninstalling it?

Cheers,
David

Hi guys, I can uninstall the program,

I went to the website and downloaded the windows troubleshooter.I chose MobaXterm and then did the procedures mentioned in the website.

Now I did the procedures, installed Xming

I ran it using No Access Controll activated.

But the same problem is happening when I run the program ./check_fluka.sh

However this doesn’t mean that everything is functioning properly
Start flair, verify that the output doesn’t contain any error or warning message
Create a small input, run and plot the results :slight_smile:

Dear Eduardo,

the correct package name should be x11-utils for Ubuntu or Debian-based systems, but the error message is only generic. In your case, the package is installed, since xdpyinfo gives you an error message.

I can only think of one cause at the moment: Maybe your firewall is interfering. If you are using the default firewall of windows you could check in Xming is allowed to pass: Couldn't connect to display - #4 by horvathd

If I understood correctly – except this warning – Flair is working correctly. Is this correct? If so I wouldn’t worry about the issue.

Cheers,
David

Dear Dávid, thank you very much for your assistance!

Unfortunately, as I needed to perform the installation as soon as possible, I chose to give up Windows and dual-boot Windows/Ubuntu on my machine.

So I can’t validate your last answer as correct, sorry.

To download on ubuntu I had few problems.

Thank you for assistance.
