DNF Updater

DNF Updater monitors and manages pending DNF5 and Flatpak updates directly from the Noctalia bar. It provides a lightweight update badge in the bar, per-package selection to skip or apply specific upgrades, download size estimation, and safe execution through Polkit (pkexec) or an interactive terminal.

Plugin

Field	Value
ID	strob3/dnf-updater
Entries	Bar widget: widget; panel: panel; service: service

Requirements

The plugin expects the following dependencies on $PATH:

• dnf5 - required for DNF, COPR, and RPM package management. Fedora 41+ uses DNF5 by default.
• flatpak - optional, Flatpak application manager
• pkexec - (Polkit authentication for non-interactive privileged package installation)

Passwordless Background Upgrades (Optional)

To enable seamless background upgrades without a password prompt (matching Flatpak's default behavior for wheel users), install the included Polkit rule:

sudo install -Dm644 polkit/50-dnf-updater.rules /etc/polkit-1/rules.d/50-dnf-updater.rules

To remove it later:

sudo rm /etc/polkit-1/rules.d/50-dnf-updater.rules

Usage

Add the DNF Updater widget to the bar using Noctalia's bar widget picker. Left-click the widget to open the updates panel. You can also toggle the panel or bind it to a compositor shortcut:

noctalia msg panel-toggle strob3/dnf-updater:panel

Shortcuts & Keybindings

You can also toggle the panel with a hotkey or shell alias:

Niri (~/.config/niri/config.kdl):

binds {
    Mod+U { spawn "noctalia" "msg" "panel-toggle" "strob3/dnf-updater:panel"; }
}

Hyprland (hyprland.conf):

bind = $mainMod, U, exec, noctalia msg panel-toggle strob3/dnf-updater:panel

Shell Alias (~/.bashrc or ~/.zshrc):

alias dnf-updater="noctalia msg panel-toggle strob3/dnf-updater:panel"
alias dnf-check="noctalia msg plugin strob3/dnf-updater:service service check"

IPC

Trigger background service operations using noctalia msg:

# Check for updates immediately
noctalia msg plugin strob3/dnf-updater:service service check

# Apply updates for all pending packages
noctalia msg plugin strob3/dnf-updater:service service update

Notes

• Privilege Separation: Noctalia never runs as root. System upgrades invoke pkexec dnf5 upgrade with explicit arguments, or launch inside the user's terminal emulator when configured.
• Selective Upgrades: When packages are deselected, DNF5 is invoked with --exclude=<pkg> arguments and Flatpak is invoked with only selected application IDs.
• Background Checks: Update queries use non-blocking JSON queries (dnf5 check-upgrade --json and flatpak remote-ls --updates -j) to prevent freezing the shell.
