So I built a new server with 18.04.2 LTS Alternative. Installed with full disk encryption and then realized I had to enter my encryption key on every reboot. It's a media server, I don't need full disk encryption. Never has the GNU GRUB window appeared when I did the initial install.
Now, after I did a fresh install without encryption, it appears every time waiting 30 seconds before booting into Ubuntu. I don't understand why, I only have one OS and I set GRUB_HIDDEN_TIMEOUT to 0.
Did I officially break my server or is this normal for non-encrypted Ubuntu? Any advice would be greatly appreciated.
