How can I download and install software on Ubuntu?

There are several ways to download and install software on Ubuntu.

1. Download and install software using the command line. Open the terminal (Ctrl+Alt+T) and use the following commands to download and install software:

sudo apt-get update
sudo apt-get install 软件名称

“Software name” is the name of the software you need to download and install.

1. Download and install software from the Ubuntu Software Center. Click on the Ubuntu Software Center icon on the left menu bar, search for the software you want to download and install in the search bar, click on the software icon, and then click the “Install” button.
2. Manually install the software using the downloaded .deb file. First, download the .deb file from the software’s official website or other reliable source. Next, double-click on the .deb file, which will open the Ubuntu Software Center and display the software’s details. Finally, click the “Install” button.

Regardless of the method you choose, you will need to provide administrator permission (i.e. enter a password) to allow the installation of the software.
