The bootstrap.dat was obtained from the following magnet link:

magnet:?xt=urn:btih:6128eb7db7f0f6db4a4baabee392242c2b9d8f8f&dn=bootstrap.dat&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce

Bootstrap creation time: September 2018 (unknown exact date)

For Ubuntu, you may need to install lz4 using:

    apt update -qy
    apt install -y liblz4-tool

To download this snapshot efficiently, make sure to download over HTTP (not HTTPS), as SSL severely impedes the download speed. 
You should decompress it on the fly with lz4 as below, allowing it to decompress while downloading, instead of after downloading:

    cd ~/.dogecoin/
    
    # Download the .dat.lz4 and pipe it into lz4, allowing it to be decompressed on-the-fly while it downloads,
    # and outputted uncompressed to the file `bootstrap.dat`
    curl -fsSL http://files.privex.io/blockchains/dogecoin/bootstrap.dat.lz4 -o - | lz4 -d - bootstrap.dat

    # Re-index Dogecoin to ensure it uses bootstrap.dat
    dogecoind -daemon -reindex

If you have the space to hold the original compressed file during decompression, and want a guaranteed reliable download,
then you may use rsync like so:

    cd ~/.dogecoin/

    # NOTE: 
    # If your connection is slow, but you have a good CPU, download the .dat.lz4 file instead of the .dat, and 
    # decompress it after downloading using `lz4 -d bootstrap.dat.lz4`
    ########### 
    # Download the .dat using rsync. It will automatically checksum the file as it downloads, ensuring no corruption,
    # and if there's a connection error, it will resume without any issues.
    rsync -av --progress --partial-dir='.rsync-partial' rsync://files.privex.io/blockchains/dogecoin/bootstrap.dat .

    # Re-index Dogecoin to ensure it uses bootstrap.dat
    dogecoind -daemon -reindex
