How to Install 7net Recorder on Ubuntu from Terminal

This guide explains how to install 7net Recorder on Ubuntu directly from Terminal. This method is useful if you prefer command-line installation and do not want to download and open the .deb package manually.

Important: only run the installation command from the official 7net source. The command below downloads the installer from https://packages.7net.vn/install.sh. Before pressing Enter, check that the domain is exactly packages.7net.vn.

Before you begin

Make sure that:

  • You are using a supported Ubuntu desktop version.
  • Your computer is connected to the Internet.
  • Your Ubuntu account can install software with sudo.
  • You know the password for your Ubuntu user account.

Step 1: Open Terminal

Open the Ubuntu application menu and search for Terminal. You can also press Ctrl + Alt + T to open a Terminal window.

Step 2: Copy and run the installation command

Copy the complete command below. Keep it on one line:

sudo apt-get update && sudo apt-get install -y curl && curl -fsSL https://packages.7net.vn/install.sh | sudo bash

Paste the command into Terminal and press Enter.

Step 3: Enter your Ubuntu password

Because the command installs software on the system, Ubuntu may ask for your administrator password. You will see a prompt similar to:

[sudo] password for your-username:

Type the password for your Ubuntu account and press Enter.

Do not worry if nothing appears while you type your password. Ubuntu Terminal normally does not show dots, stars or other characters for sudo passwords. The password is still being entered.

Step 4: Wait while Ubuntu installs the required packages

After authentication, Ubuntu will update its package information, install curl if needed, download the official 7net installation script and install 7net Recorder together with the required Linux components.

You may see many lines such as Setting up... and Processing triggers.... This is normal. Keep Terminal open and wait until the process finishes.

The installation may take a few minutes depending on your Internet connection and whether some required packages are already installed.

Step 5: Confirm that the installation finished successfully

When installation is complete, Terminal will display:

7net-recorder installed successfully.

The normal command prompt will then appear again. At this point, the installation is complete.

Step 6: Open 7net Recorder

Open the Ubuntu application overview and search for 7net Recorder. Click the 7net Recorder icon to start the application.

You can then choose your display, system audio, microphone and webcam, select the recording settings, and start recording.

Installation complete. 7net Recorder is now installed on your Ubuntu computer and ready to use.

What does the installation command do?

The command contains three parts:

  1. sudo apt-get update
    Refreshes Ubuntu package information.
  2. sudo apt-get install -y curl
    Installs curl if it is not already installed.
  3. curl -fsSL https://packages.7net.vn/install.sh | sudo bash
    Downloads the official 7net installation script and runs it with administrator privileges.

The && operators make the next command run only if the previous command completes successfully.

If the installation command does not work

Try the following checks:

  • Make sure your Internet connection is working.
  • Check that you copied the complete command.
  • Make sure the command is entered on one line.
  • Verify that the URL is exactly https://packages.7net.vn/install.sh.
  • Close Terminal, open it again and retry the command.
  • If Terminal installation still fails, use the official .deb installation method instead.
Security reminder: commands that use sudo have administrator privileges. Only run installation commands from sources you trust and verify the domain before continuing.
