Regolith can be installed as system packages. This makes updating and removing easy and consistent. The following steps describe how to configure your system to read packages from the Regolith package repository and install the desktop package.

1. Register the Regolith public key to your local apt:

   wget -qO - https://regolith-desktop.io/regolith.key | \
   gpg --dearmor | sudo tee /usr/share/keyrings/regolith-archive-keyring.gpg > /dev/null
   

2. Add the repository URL to your local apt:

   echo deb "[arch=amd64 signed-by=/usr/share/keyrings/regolith-archive-keyring.gpg] \
   https://regolith-desktop.io/release-ubuntu-jammy-amd64 jammy main" | \
   sudo tee /etc/apt/sources.list.d/regolith.list
   

Substitue arm64 for amd64 in the two places in the above line to install on ARM-based systems.

1. Update apt and install Regolith

   sudo apt update
   sudo apt install regolith-desktop
   sudo apt upgrade

To install Regolith 2 into an existing Ubuntu system that is upgrading to 22.04, follow these steps:

1. Upgrade the system to all the latest packages on current release (either Ubuntu 20.04 or 21.10)

2. Perform the Ubuntu system upgrade to 22.04, however DO NOT reboot as prompted until the following steps are completed

3. After the 22.04 upgrade completes, add the Regolith 2 package repository:

   wget -qO - https://regolith-desktop.io/regolith.key | gpg --dearmor | sudo tee /usr/share/keyrings/regolith-archive-keyring.gpg > /dev/null
   echo deb "[arch=amd64 signed-by=/usr/share/keyrings/regolith-archive-keyring.gpg] https://regolith-desktop.io/release-ubuntu-jammy-amd64 jammy main" | \
   sudo tee /etc/apt/sources.list.d/regolith.list
   sudo apt update
   

4. Next install the Regolith 2 desktop package:

   sudo apt install regolith-desktop # See configuration page for additional packages 
   sudo apt dist-upgrade
   

5. Now reboot the system and select the regolith session at the login screen

Custom configurations from Regolith 1.6 will need to be manually ported to Regolith 2. In order to make this upgrade simpler, Regolith 2 uses the user config directory of ~/.config/regolith2. It will not read files from the Regolith 1.x user config directory ~/.config/regolith. Please refer to the configuration page for more details.
