i was building the debian setup of yocto. i was able to get apt-get working but it has no source.list . therefore it was not able to find any package.
Things i tried(didnt worked)
1. Copying source.list from ubuntu 16.04 . - failed due to not finding server for arm64 while "apt-get update"
2. tried some source.list from dockers forum but didnt worked either.
i want to do pip install pymavlink. pip is working but for pymavlink i also have to do "apt-get install python3-dev" but cant system cannot reach the package repo
