@maxiauer, could you please try the deb target for Linux here. Let me know if you have any issues downloading the artifact.

Please note, this is not an official Arduino IDE build; it's from my fork to test if the deb target solves the ibnss3.so: cannot open shared object file: No such file or director problem.

@kittaakos

Yeap, it works !!! Missing dependencies are correctly detected and installed. I was not able to plug an Arduino board due to lack of time, but the app loads without any issue.
You can see libnss3 detected as missing and installed (among other dependencies)

Thank you so much for the help with the verification, @maxiauer. I am closing the PR; the Arduino team can decide how to proceed with this.
