Installation errors

[stemy2]

Hello,

I have some problems during the installation process. After addong the ppa and doing an apt update, i get this:

Err :12 http://ppa.launchpad.net/morphis/anbox-support/ubuntu hirsute Release
  404  Not Found [IP : 91.189.95.85 80]

E: Repository http://ppa.launchpad.net/morphis/anbox-support/ubuntu hirsute Release doesn't have Release file.
N: Updates from such a repository cannot be done securely, and are therefore disabled by default.

So i installed the deb file manually. But now, i can't install the headers.

Do not try to compile the modules for newer kernels as it is not possible anymore. Instead you need to compile THE KERNEL itself with the modules options enabled in the config file as the modules had been migrated to the newer kernels but some code had been removed that prevents you from building/using the modules standalone for security reasons.

You can look at my tutorial/notice i wrote down to address the issue for myself or use my precompiled kernels (with the android config options pre-enabled) if you are using a ubuntu distribution.
