Fix “exec /gns3/init.sh: no such file or directory”

This problem can easily occur on new installations and can be hard to figure out. In a GitHub issue, the solution that fixed it for me was using Debian’s busybox:

  1. Get into a temporary folder

    cd /tmp

  2. Get and extract the Debian binary

    wget -q http://launchpadlibrarian.net/471755664/busybox-static_1.30.1-4ubuntu6_amd64.deb
ar x busybox-static_1.30.1-4ubuntu6_amd64.deb
tar -xf data.tar.xz

  3. Move it to the proper location, your path may differ slightly

    sudo mv ./bin/busybox /usr/lib/python3.11/site-packages/gns3server/compute/docker/resources/bin/busybox
