arm-none-eabi-g++: no such file or directory

[caternuson]

OS = Ubuntu 24.04.1 LTS 64bit
Arduino 1.8.19
arduino-nRF5 BSP 0.8.0
Tools -> Board = BBC micro:bit V2

Example sketch:

void setup() {
}

void loop() {
}

Then just do a compile test and it ends with:

fork/exec /home/user/.arduino15/packages/sandeepmistry/tools/gcc-arm-none-eabi/5_2-2015q4/bin/arm-none-eabi-g++: no such file or directory
Error compiling for board BBC micro:bit V2.

The file actually exists.

Trying to install the 32bit packages results in:

$user> sudo dpkg --add-architecture i386
$user> sudo apt-get update
    ** lots of output, no errors **
$user> sudo apt-get -y install libc6:i386 libstdc++6:i386 libncurses5:i386 libudev1:i386
