I'm not sure of the reason for the failed builds. It's not me right?

Debian 9 and Ubuntu 16.04 are EOL, you can ignore failures (if you want, you can rebase on top of master to integrate their removal):

From your working directory:

git fetch origin         # Download the latest code we have here
git rebase origin/master # Move your commits on top of the main branch
git push -f              # Send the changes (-f is required because you re-wrote history)

Hey @gerases, can you rebase this and fix the merge conflicts? :) If the CI passes then, I can merge it

@zilchms , done, let me know if you need me to do anything else
