In our second session of Terminal Tuts, we shall learn how to install updates on the Ubuntu based distros by command-line using Terminal. We shall also see how to only install security updates and not all regular updates by command line. This is especially useful when you are pushing the updates via remote login where use of terminal shines!
Install Updates on Ubuntu, Linux Mint, and elementary OS from Terminal
Launch Terminal and enter the following commands:
Step 1: Fetch the updates available for your computer using apt-get update command:
sudo apt-get update
Step 2: You can then use apt-get upgrade command will upgrade the current packages
sudo apt-get upgrade
Step 3: Finally use the distribution upgrade command. This command also intelligently handles changing dependencies with new versions of packages. It will attempt to upgrade the most important packages at the expense of less important ones if necessary. The dist-upgrade command may therefore remove some outdated and broken packages.
sudo apt-get dist-upgrade
Install Only Security updates on Ubuntu, Linux Mint, and elementary OS from Terminal
At times to save time on remote machines, you may want to launch terminal and only install the security updates.
You can use the unattended upgrade command which will silently install updates without user interaction.
sudo apt-get install unattended-upgrades
Instead, if you want to have a interactive installation, use the display parameter:
sudo apt-get install unattended-upgrades -d
