I can't launch Roadrunner after installation

My machine specs:

1. Ubuntu 22.04.1
2. 32GB memory, Intel Core i9 x 16
3. One GeForce RTX 3080 + one integrated Intel UHD Graphics (could this be the reason of issue?)
4. Roadrunner ver: R2021b

Problem description:

1. Clicking the icon, nothing happened
2. Going to /usr/share/applications and clicking "RoadRunner_R2021b.desktop", it gave "Failed to add a plugin to the panel" + "GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.xfce.Panel was not provided by any .service files"

What I tried:

1. I found https://www.mathworks.com/matlabcentral/answers/1460889-roadrunner-can-t-be-launched, and followed Kyle's instruction, but it gave me "./AppRoadRunner: errror while loading shared libraries: libidn.so.11: cannot open shared object file: No such file or directory".
2. I tried to install Roadrunner R2022b in the first place, but I couldn't even get it installed. It gave "buffer error", "error exit status 2"

Ubuntu 22.04 is... too new to run RoadRunner R2022b. The newest verison of Ubuntu that it support is 18.04, so you have to do some funky stuff to get it working.

If you make symoblic links to libidn.so.12 that 22.04 ships with, put them in the place that RoadRunner expects them to be in, and then name the symoblic link after libidn.so.11, then it should work, I believe.

More specifically, run these commands:

• sudo ln -s /usr/lib/x86_64-linux-gnu/libidn.so.12 /usr/lib64/libidn.so.11
• export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/libidn.so.11 (you'll probably want to add this to your bash.rc file.)

If it still returns an error, you want to go to /usr/local/RoadRunner_R2022a/bin/glnxa64/ and rename the following files, so they have an “.old” extension at the end of them:

• libdrm.so.2
• libXi.so.6
• libX11.so.6
• libXau.so.6
• libXext.so.6
• libXdmcp.so.6
• libXfixes.so.3
• libXdamage.so.1
• libXrender.so.1
• libXxf86vm.so.1
• libxshmfence.so.1
• libcurl.so.4

Thank you Jestzer! I've tried your solution but unfortunately it still won't work. Now I'm using a Win 10 machine instead.

I’m curious, what happened when you tried that?

Also if you want to use Liunx with RoadRunner, try Debian 11. It seems to work for me without any issues even though MathWorks doesn’t list it as supported.

For the future reference - this seems to work. Tested on Ubuntu 22.04, R2023b
