I use 20.04 with no problem, so it’s probably something with your `LD_LIBRARY_PATH` or other config. You can try running `Slicer --launch xterm` and then run `SlicerApp-real` in the new window to see if there is more diagnostic info. Also inside that window you can try `ldd $(which SlicerApp-real)` to see if any of the core slicer or python libraries are pointing outside of your install tree.

Qt libraries, along with all required dependencies are distributed. You should not have to install Qt.

This seems to indicate the application started but it crashed once the Welcome module is loaded.
Could you try:
```auto
./Slicer --modules-to-ignore Welcome
```
Does the application start ? Are you able to select other modules ?

This may not be the issue, but is there a reason why you install this in root? Are you running the application as root?
