The problem here is that we don't have a release distributed for linux-armv7 of arduino ctags.. This will be partially solved by arduino/arduino-cli#2285

[ChillarAnand]

Doesn't RPi 4 use linux-armv8(64-bit)?

Doesn't RPi 4 use linux-armv8(64-bit)?

True. 32bit os is running in arm-v7 (armhf) compatibility mode even though the processor is arm-v8 capable. 64-bit aarch64 is running in arm-v8.

cat /etc/apt/sources.list or lsb_release -a

reveal the software version.

@umbynos Is there now a vay to circumvent this issue? I'd like to run arduino-cli on my 32-bit rpi4b

edit, workaround

This workaround worked for me, as I had already arduino-ctags package installed via apt

cd 
cd .arduino15/packages/builtin/tools/ctags/5.8-arduino11
mv ctags orig.ctags
ln -s /usr/bin/arduino-ctags ctags

after this build was successful and code ran on nano every.
