Get Regolith

Regolith is available as a stand-alone ISO that can be installed as a complete Linux operating system and as a "personal package archive" (PPA) that installs the Regolith desktop into an existing Ubuntu 18.04 or 19.10 system.

Regolith Linux ISO Installer

Starting from scratch or simply want to try Regolith out in a VM or LiveUSB environment? Download the ISO and write it to a USB flash drive to install or test drive Regolith as an operating system. To learn how, visit the Ubuntu installer tutorial. This ISO is a customization of the Ubuntu installer from Canonical, with some optional packages removed and Regolith packages added.

Regolith Desktop PPA

Add the Regolith PPA to your existing Ubuntu system and install the regolith-desktop package with the following terminal commands:

$ sudo add-apt-repository ppa:regolith-linux/release
$ sudo apt install regolith-desktop

After installation, Regolith will appear as a desktop session on the login screen. Learn more about adding PPAs here.

Upgrade from earlier version

To upgrade your existing 1.1 or 1.2 version of Regolith to 1.3, simply move to the new PPA and perform a dist-upgrade:

$ sudo add-apt-repository --remove ppa:kgilmer/regolith-stable
$ sudo add-apt-repository ppa:regolith-linux/release
$ sudo apt dist-upgrade

If you have made customizations to i3wm or your styles, it's recommended to use the defaults upon login and then manually integrate your changes back in. To ensure that the defaults are loaded, move your changes and then log back in.

$ mv ~/.config/regolith ~/old-regolith-config
$ mv ~/.Xresources-regolith ~/old-regolith-styles
$ # now log back in

Remove Regolith Desktop

If you decide Regolith isn't what you're looking for, restore your previous GNOME settings and completely remove Regolith by logging in to the standard Ubuntu session and executing the following commands from a terminal:

$ sudo add-apt-repository –remove ppa:regolith-linux/release
$ sudo apt remove regolith-*
$ sudo apt autoremove
$ source ~/.regolith-gnome-backup
$ rm -Rf ~/.regolith-gnome-backup ~/.config/regolith

Earlier Releases

While Regolith is a young project, it already has a few releases behind it. You can find earlier ISO installer releases on SourceForge.net.
