Stuck on downloading - Linux (devel)

[sum01]

EDIT: Why is this labelled enhancement and not bug?

• [x] I have read CONTRIBUTING.rst

Tribler version/branch+revision:

cddfbad065c9a1425e3889f2d45391d15da8480b

Operating system and version:

Linux 4.11.6-3-ARCH

Steps to reproduce the behavior:

Installed via my custom PKGBUILD

cd /usr/share/tribler
./tribler.sh

Then added Ubuntu 17.04 torrent to test (after enabling 2 hops).

Expected behavior:

The torrent downloads anonymously via 2 hops.

Actual behavior:

It pulls meta data and builds circuits, then hangs at 0% on Downloading.

Relevant log file output:

Mostly spam of WARNING:Timeline:FAIL time:6 user:11262 -> permit^channel (no authorization) but with various times and user nums.

Between spam of the timeline fails it also shows lots of WARNING:AllChannelCommunity:drop a 123 byte packet duplicate message by member^global_time (1) [dispersy-undo-own] from {LOCAL_IPHERE IPHERE}

And also some WARNING:AllChannelCommunity:drop a 123 byte packet duplicate message by member^global_time (1) [dispersy-undo-own] from {LOCAL_IPHERE IPHERE}

Did the torrent have UDP trackers? Some torrents only have HTTP trackers, which we don't allow to avoid abuse of our anonymization network. Consequently, torrents with only HTTP trackers will need to use pure DHT, which can take a long time (and/or not start at all if other peers don't support/allow DHT).

Well it's the official Ubuntu torrent download. I've tried with both 17.04 and the 16 LTS, both get stuck on

0% Downloading

When I click trackers it shows DHT as working, but with 0 peers. In fact, it shows all the trackers as having 0 peers.

I was about to close Tribler when I got this

@sum01 This is a separate issue. Would you be so kind to create a separate issue ticket?

[sum01]

Tried 7.0.0-rc3 via the current AUR pkgbuild and it's basically the same issue, it gets stuck on retrieving metadata.

[devos50]

This torrent does not have any UDP trackers, therefore it will not bootstrap into the swarm. We plan on supporting TCP trackers but this is a lower-priority issue (#2681)

[sum01]

I have this happen with all torrents I've tried. Is there a torrent I can test to see if it works as intended?

[qstokkink]

You can check them in http://torrenteditor.com/ and see if the trackers start with udp:// (as mentioned support for trackers starting with http:// is not implemented).
