Why can't download the magnet with aria2c command?

Question

The Battlestar Galactica here
http://kickasstorrentsan.com/usearch/Battlestar%20Galactica/
can be downloaded with deluge.

Now i scrap the magnet with firebug on the web page.

It can be verified that the magnet is :

magnet:?xt=urn:btih:2D2CAE6AC83800490327547053597BAFF6701C2F&dn=battlestar+galactica+season+1+s01+1080p+bluray+x265+hevc+aac+5+1+joy+utr&tr=udp%3A%2F%2Ftracker.publicbt.com%2Fannounce&tr=udp%3A%2F%2Fglotorrents.pw%3A6969%2Fannounce&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce

The bash script were written as following:

1.the $url variable is right address for magnet.
2.aria2c command can be executed correctly.
3.aria2c $url has beeen executed for about one hour.Why nothing can be dowlonaded?

Not sure what the issue is, but it is suggested that you do aria2c "$url" – Megasporangium

aria2c "$url" can't work ,it was tested ,failed. – Disinfect

The point was not aria2c "$url" will work, even in a working version it is suggested to double quote $url to avoid word splitting. – Megasporangium

I have given you the gift after my verification. – Disinfect

This page says, you need to enable DHT option while downloading using magnet-links:-

This official documentation page says, it is enabled by default from version 1.25.0

--enable-dht[=true|false] Enable IPv4 DHT functionality. It also enables UDP tracker support. If a private flag is set in a torrent, aria2 doesn't use DHT for that download even if true is given. Default: true

Checked the release notes from GitHub, couldn't find the exact release since the flag --enable-dht has been made to true.

Upgrade to the latest version to have the flag enabled by default (or) enable it explicitly if you are using an older version.

aria2c --enable-dht=true "magnet:?xt=urn:btih:2D2CAE6AC83800490327547053597BAFF6701C2F&dn=battlestar+galactica+season+1+s01+1080p+bluray+x265+hevc+aac+5+1+joy+utr&tr=udp%3A%2F%2Ftracker.publicbt.com%2Fannounce&tr=udp%3A%2F%2Fglotorrents.pw%3A6969%2Fannounce&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce"
