That moment you receive an email: your CI build is failing.

Ok. What went wrong?

Three new commits that do not seem to alter anything related to the failure.

*reverts commits and tries again*

Still failing.

WTF?!

*restarts previous builds*

They now fail too.

FUCK! BASTARD! Are you kidding me?

*investigates*

Turns out that repo of dependency changed and is not compatible anymore.

Argh! Son of bitch!
