I found the solution here: https://forums.raspberrypi.com/viewtopic.php?t=358951

cd ~/pico
sudo apt install libusb-1.0-0-dev
git clone https://github.com/raspberrypi/picotool.git
cd picotool
mkdir build
cd build
cmake ..
make
sudo ln -s ~/pico/picotool/build/picotool /usr/local/bin/picotool

Note: using the pico-sdk branch 1.1.2 is failing on Ubuntu 24.10:

make[1]: *** No rule to make target '/home/alan/pico-sdk/src/rp2040/boot_stage2/boot2_w25q080.S', needed by 'rp2040_boot_stage2.elf'.  Stop.
make: *** [tools/Unix.mk:548: nuttx] Error 2

This is similar to the findings in #13483.

I opened a PR to change the docs for the Pico and Pico W but it appears other pages need updating too. I believe the Pico SDK back-ported changes from 2.0.0 to other versions which broke 1.1.2, but I can't find evidence of that in their git history.

Thank you @linguini1 !!! Actually, compiling/installing the picotool and using version 2.0.0 works fine, but we need to check if WiFi still working for this version as well.
