Package conflict with gcc-avr

I just installed gcc-arm-embedded, v7-2018q2-1~bionic1 on an Ubuntu 18.04 system using your instructions [1]. Before installing I removed the gcc, binutils, libnewlib, and libstdc++ packages for arm-none-eabi.

However, I also happened to have the gcc AVR toolchain packages installed. There was a conflict when installing gcc-arm-embedded. The file below already was managed by the gcc-avr package, at revision 5.4.0+atmel3.6.0-1build1.

/usr/lib/libcc1.so.0.0.0

I uninstalled the gcc AVR toolchain packages, and was able to install gcc-arm-embeded. However, maybe you can find a way for future release packages to coexist.
