Before You Begin
A few things to check before starting the upgrade.
Backup your data
Although the upgrade is safe, always back up important files before major system changes.
Use tmux or screen
The desktop will restart during upgrade. Run inside tmux so the terminal survives GUI restarts.
Connect to power
The upgrade may take 30-60 minutes. Plug in to avoid interruptions.
Stable internet connection
Packages will be downloaded during upgrade. A stable connection is required.
On AnduinOS 1.3.9 or 1.4.2
Make sure you are on the latest 1.3.x or 1.4.x version. Run the upgrade tool to update first if needed.
At least 3 GB free space
The upgrade needs space for package downloads and backups. Ensure you have enough free space in /.
One Command to Upgrade
Run this single command in your terminal. The upgrade is fully automated — no manual intervention needed.
