Go version:

go version go1.6.1 linux/arm

Is there any more information required ?

Thanks for the report. Does this occur with all torrents? I presume you've installed from source? If yes and yes, I'm guessing there's been some upstream changes to github.com/anacrolix/torrent which might have broken things...

vedarthk commented 8 years ago

@jpillora yes OK. Yes I have installed from the source. It is failing at: https://github.com/anacrolix/torrent/blob/master/t.go#L106

Looks like following commit has made those changes: https://github.com/anacrolix/torrent/commit/1fab7653294ece3ccd1589cbea9c3b0c77d0f1e6

jpillora commented 8 years ago

Okay cool. When I can, I'll swap from godeps to vendor, which will fix this issue. In the meantime, the pre-built binaries should work fine.

For those interested in compiling from source and are willing to help out, see https://github.com/jpillora/cloud-torrent/issues/51
