On Ubuntu Server 18.04.03 LTS, fresh install, I wanted to do edit some kernel command line settings. In /etc/default/grub, I found the following set:


I'm a Linux power user, but never really tried Ubuntu. So quick Google tells me that Ubiquity is the Ubuntu installer. Why would a production server want to run the installer maybe?

Can I delete this entry? This is for a client's in-house server and I don't want to give anybody options to enter into an installer (accidentally). Furthermore, I have my own ways of getting into crippled systems. No need for an installer to help me.

    The maybe-ubiquity boot parameter is for the desktop installer, and not for server. Perhaps something is overwriting the configuration, similar to this bug: /etc/default/grub.d/50-curtin-settings.cfg overwrites GRUB_CMDLINE_LINUX_DEFAULT (1527664)

    This parameter is set after a vanilla Focal Fossa server installation. I wonder why.

    I just removed it cause I dont need the ubiquity installer. After removing this option from /etc/default/grub you need to run update-grub. Nov 2, 2020 at 19:21
  • @user37165 I do not agree that the maybe-ubiquity parameter is present only on desktop installs. In my case I installed an Ubuntu 20.04 Server and the parameter is present. It seems it is a bug. Apr 5, 2022 at 8:32

AFAIK this param resides in the DEFAULT commandline after one has installed the system from a LiveCD/DVD image.

Ubiquity is an installer system Ubuntu uses on the live systems, there seems to be a bug that keeps this param also in the default commandline after installation.

I think it's safe to remove from GRUB_CMDLINE_LINUX_DEFAULT.
