The latest LTS version is Ubuntu 20.04, while the latest non-LTS version is Ubuntu 21.04.

Choose Your Download Method
The next step is to choose how you want to download Ubuntu live ISO. There are several options:
Direct download: This is the simplest and fastest way to download Ubuntu live ISO. You just need to visit the download page and click on the green button that says "Download". This will start downloading the ISO file to your computer.
Torrent: This is an alternative way to download Ubuntu live ISO using a peer-to-peer network. You need to install a torrent client, such as BitTorrent or uTorrent, and then download the torrent file from the download page. This will start downloading the ISO file from multiple sources, which can be faster and more reliable than direct download.
Network installer: This is a way to download Ubuntu live ISO using a minimal image that contains only the essential components. You need to download the network installer image from the alternative downloads page and create a bootable USB or DVD from it. Then you need to boot from it and follow the instructions to download the rest of the files from the internet.
Alternative downloads: This is a way to download Ubuntu live ISO using other methods, such as zsync, jigdo, or HTTP mirrors. You can find more information about these methods on the alternative downloads page.
Verify Your Download
The last step is to verify your download to make sure that the ISO file is not corrupted or tampered with. You can do this by checking the checksums and signatures of the file. A checksum is a string of numbers and letters that represents the content of the file. A signature is a digital certificate that confirms the authenticity of the file.
You can find the checksums and signatures of Ubuntu live ISO on the official website. You need to compare them with the ones you get from your downloaded file using a tool such as MD5SUM or GPG. If they match, it means that your download is valid and safe. If they don't match, it means that your download is corrupted or compromised and you need to download it again.
