tips on how to install Arduino IDE v1.8.13 on modern distribution

[UltraMej]

Hello,

As you advise the IDE v 1.8.13 as the only ARDUINO that runs mTC out of the box; I tryed installing it (on Kubuntu 25.10)...

• I download it from: https://github.com/arduino/Arduino/releases/tag/1.8.13 following the link https://github.com/arduino/Arduino/releases/download/1.8.13/arduino-1.8.13.tar.xz
• I extract the archive
• when I excecute $ sudo ./build/linux/dist/install.sh I get the following error messages:

Anybody help?
How do you install the IDE v 1.8.13 on modern linux distrib?

(PS: I also created an issue on the ARDUINO git, but not sure if they still support version prior to 2.x... arduino/Arduino#12117)
