Update Ubuntu, Debian or Linux Mint

By HelpAstuce team

On Debian-based distributions, the apt package manager updates the system and your software in one go. Snap and Flatpak apps update separately.

1. Open the terminal

   Press Ctrl + Alt + T. Commands with sudo ask for your password; nothing appears while you type, which is normal.

2. Refresh the package list

   sudo apt update

   bashCopy

   This changes nothing on the system: it fetches the list of available versions.

1. Install the updates

   sudo apt upgrade -y

   bashCopy

2. Remove unused packages

   sudo apt autoremove -y

   bashCopy

3. Update Snap and Flatpak

   If you use these app formats:

   sudo snap refresh
   flatpak update -y

   bashCopy

Good to know : To move to a new Ubuntu release, use sudo do-release-upgrade after backing up your files.
