You can put ubuntu-20.04.1-desktop-amd64.iso on a bootable USB stick.
See e.g. https://www.tecmint.com/create-bootable-ubuntu-usb-disk/
howto do that and boot from USB to a live ubuntu 20.04 desktop.
Next I use a script which installs the main browsers, like google-chrome, opera
video player gmplayer and other toolsi, like ssh sshd . Download : https://crashrecovery.org/2004.1.zip

There's a newer better version of youtube-dl,  a so called fork : yt-dlp
