Cannot install the browser on Robolinux 10.9 on my laptop (x86_64)

Cannot install the browser on Robolinux 10.9 on my laptop (x86_64).
Can you help me please. Also I couldn’t understand or do the installing instructions written on the site.

@avare27,
While I don’t have any experience with this particular Linux distribution, I would recommend trying the instructions on our site for installing Brave on Linux Mint first. Performing the installation instructions is quite simple – while you can enter the entirety of the text at once, I would recommend executing one line of commands at a time. So, try the following
as per our installation instructions:

  1. On your system, open the Terminal application.

  2. In the Terminal, enter the first line of commands in the instructions:

    sudo apt install apt-transport-https curl 
    
  3. Then enter the second command:

    curl -s https://brave-browser-apt-release.s3.brave.com/brave-core.asc | sudo apt-key --keyring /etc/apt/trusted.gpg.d/brave-browser-release.gpg add -
    
  4. Note that if you see the system running or processing anything in Terminal, wait for it to finish before entering the next command. Fourth command:

    echo "deb [arch=amd64] https://brave-browser-apt-release.s3.brave.com/ stable main" | sudo tee /etc/apt/sources.list.d/brave-browser-release.list
    
  5. Now to finish up, enter the update command:

    sudo apt update
    
  6. Then finally the install command:

    sudo apt install brave-browser
    

Try the above and let me know if this works for you.
