[bwanaaa]

Added this to prefs:
https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json
Went to board manager and search for stm32 and got this error

it tells me to use the new package index

I add the new package index
https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmelectronics_index.json
but no packages are found.

Help
