Hello, recently I found the following packages installed on travis amd64 virtual machine but not on travis arm64 container:
python-pip
python3-pip
python-setuptools
python3-setuptools
python-dev
python3-dev
libtool
As a result, open source projects need some CPU specific shell script to install the missing packages. It would be better to keep the installed packages as congruent as possible for multiple architectures.
