Arduino compile problems

Problem: Unable to compile any sketch for Aerocore 2 for Jetson.

System: Ubuntu 18.04, Arduino IDE 1.8.5
I followed the directions in stm32f4_0/README.

Here's what I get:

Then I run apt-get install gcc-arm-none-eabi and edit .arduino15/packages/aerocore-2-for-nvidia-jetson-arduino-bsp/hardware/stm32/1.0.0/platform.txt and change
compiler.path={runtime.tools.arm-none-eabi-gcc.path}/bin/
to
compiler.path=/usr/bin/
and now here's what I get:

There was an error in the arduino hardware variant definition for the STM32 and it has been corrected. Please uninstall and delete the package and reinstall it.

• After you have uninstalled the package from the device manager interface you will need to remove the zipfile found at ~/.arduino15/staging/packages/aerocore-2-for-nvidia-jetson.zip or the interface will reinstall the old package.
• Add this link to the contributed URL field in settings if you haven't already.
• Use the device manager to install the Aerocore 2 package.

Thanks. I had to take the following additional steps:

• Uninstall gcc-arm-none-eabi -- it doesn't work
• Install gcc-arm-embedded from ppa:team-gcc-arm-embedded/ppa instead
• Remove a stray "*/" from the end of PeripheralPins.c
• Still had to change "compiler.path={runtime.tools.arm-none-eabi-gcc.path}/bin/" to "compiler.path=/usr/bin/" -- your package doesn't provide runtime.tools.arm-none-eabi-gcc so {runtime.tools.arm-none-eabi-gcc.path} returns nothing
• Change both instances of "$(dirname $0)/dfu-util/dfu-util" to "sudo $(dirname $0)/dfu-util/dfu-util" in dfu_upload.h
• Start the Arduino IDE from a terminal so sudo password can be entered for DFU loading.
  After that I got it to work.
