  • Firstly, run this command “lsb_release -a” on your Ubuntu device to know your device version.
  • Your OS version and codename will be displayed on the screen. Note down the codename.
  • Now, it’s time to know the package codename that you want to install.
  • Go to https://packages.ubuntu.com/ website.
  • Scroll down and find the Search section.

sudo apt update

Now try to install again. If you still get the error message, then try the next method.
