please i tried downloading ubuntu from their website and it keeps saying "the connection was reset. how do i get to download it still please
It could be that the site is down/having intermittent problems. Have you tried at different times or days? If not just wait and try again tomorrow. Do you have problems downloading other large (multi-gigabyte) files? Is your computer sleeping during the download?
Alternatively, you could download it via BitTorrent, which would avoid issues with their website, computer sleeping, etc.
I would 2nd trying the torrent method. If possible, try an ethernet connection to your router to ensure a steady internet connection.
