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
Note
Software that was installed from outside of an apt repository won’t be
upgraded automatically or by running the above commands. Examples of software
installed from outside of an apt repository include software:
- Installed using
pip - Installed in Anaconda
- Installed using
snap - Installed from a
dpkg - Downloaded from a Git repository
- Installed from a tarball
- Built from source code
