The first is a clue to the second. Your apt cache has no cross-build-essential.
Try running apt-get update first, then the apt-cache command gain, if you find a candidate install it and move on. If not the problem is your DVD safe probably the only install source you have installed. Try something like Tell dpkg we can install arm64 dpkg --add-architecture arm64 # Add src line to make "apt-get source" work echo "deb-src http://deb.debian.org/debian buster main" >> /etc/apt/sources.list echo "deb-src http://deb.debian.org/debian buster main" >> /etc/apt/sources.list apt-get update You may have to use google to get these commands right. Pretty sure 10 is buster. Jim On Sat, Sep 14, 2019, 1:06 PM Brian Tremaine <[email protected]> wrote: > I now have Debian 10 (Buster) in a VirtualBox 6.0 VM on a Windows 10 > laptop.
