Updates

Installed automatically, in the background

• Ubuntu security updates and stable updates.
• The COSMIC desktop, LibreWolf, Proton VPN, Mullvad VPN and Claude Code — from their makers’ repositories.

Updates never restart the computer for you; kernel updates wait for your next restart. Configuration files you changed are kept, and your home folder is never touched. Snap is blocked from coming back.

Shortly after the first boot

A one-off catch-up installs whatever was published since the ISO was built. It runs on mains power, or with at least 50 % battery, and never delays the desktop. If you’re offline it simply tries again at the next boot.

When you choose

Feature updates outside those repositories wait for you:

sudo apt update && sudo apt upgrade

That covers Ubuntu backports, VSCodium and the GitHub CLI. Flatpak apps update through the Store.

What updates don’t change

Package-level only

Updates install new versions of packages. Arkyn’s own defaults — branding, wallpapers, theme, dock, new settings files, Arkyn Setup itself — reach an existing install only by installing a newer ISO, until an Arkyn package repository exists.

An unofficial desktop archive

COSMIC isn’t in Ubuntu’s archive yet, so it comes from a community package archive and updates automatically. A bad upstream build could reach machines unattended — a known, accepted risk for now.
