Hi rootkiter,

I tested at 90f3701f834aadb75f6d92fd8157fe0cbab0fc52 with the Docker setup: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/90f3701f834aadb75f6d92fd8157fe0cbab0fc52#docker which currently uses Ubuntu 18.04, and it did go past the apt install install command.

Also the apt install command appears to work fine in my Ubuntu 19.10 host.

I would just try to google for "E: Unable to correct problems, you have held broken packages." and see if any of the solutions work for you, e.g.: https://askubuntu.com/questions/363200/e-unable-to-correct-problems-you-have-held-broken-packages all that needs to work for now is the apt install command. Also see if it goes forward after removing libsdl2-dev.

Let me know if you find something out.
