Why this?

Many Ubuntu users face challenges with automatic updates, especially when using Firefox Snap or Deb installations. This script offers a reliable solution for those who prefer manual installations or need to bypass restrictions imposed by certain distributions.

A demonstration of system updates, package management, and scripting in BASH and ZSH — valuable for Ubuntu users and developers alike.

Features

• Exampled upgrades via release URLs under "$HOME/my_applications/$app_name"
• Works well for distros that block applications like Firefox in Snap or Deb, or preferring a manual install
• Exampled neovim, fwupdmgr, flatpak, rust toolchain upgrades
• Snap refresh is run first to prevent delays
• APT update/upgrade
• Optional cleanup steps
• BASH and ZSH scripts

Requirements

• BASH or ZSH
• Git

Setup and Usage

1. Clone this repo and make scripts executable:

   git clone --recurse-submodules https://github.com/m1st0/ugu.git ugu
   cd ugu
   

   If the project was already cloned without its submodules:

   git submodule update --init --recursive
   

2. Make the desired scripts executable:

   chmod +x ugu.zsh
   chmod +x ugu.sh
   

3. Run the script of your chosen shell:

   ./ugu.sh
   ./ugu.zsh
   

Mozilla (and Zen) Update Strategy

Unlike Snap or Apt installs, this script checks Mozilla’s (Zen's) release site and updates your manually installed Firefox/Thunderbird/Zen if needed. There used to be issues with the Snap and Apt install changes. I have opted for a manual Mozilla product installation, which allows for custom update checks.

Your Firefox/Thunderbird/Zen must previously and respectively installed into:

$HOME/my_applications/firefox/
$HOME/my_applications/thunderbird/
$HOME/my_applications/zen/

The script will:

• Detect the current version from the binary
• Compare it to Mozilla's latest .tar.xz release
