URSim - NO CONTROLLER error with missing xmlrpc library

I just installed a new computer. I have one working perfectly with ubuntu 16 but I used ubuntu 18 for this new computer.

I installed everything and tried all I could found on the forum and can’t get the error "Segmentation fault (core dumped) away from the URControl if I’m not running it as root.

So, these are some information I noticed if that can help find a solution. In my case, I will install Ubuntu16 for now.

See below debugger :

Starting program: /home/gub/ursim/ursim-5.1.2.40245/URControl

I also noticed that on ubuntu18 when you install the ursim, it’s removing the package “libcurl4” to install “libcurl3” but apparently libxmlrpc-core-c3 depends on libcurl4 ( The following packages have unmet dependencies:
libxmlrpc-core-c3 : Depends: libcurl4 (>= 7.16.2) but it is not going to be installed) can this cause some kind of conflicts?
