How do I upgrade software in Ubuntu?

Ubuntu regularly checks for new versions of software installed from an apt repository, including:

  • Ubuntu system updates
  • Ubuntu security updates
  • Lambda Stack

However, only Ubuntu security updates are automatically installed. Other updates must be installed manually.

To manually check for and install new versions of software installed from an apt repository, run the following commands in a terminal:

sudo apt-get update && sudo apt-get upgrade
