This is a build issue with libtorrent

Maybe. Please tell me how to fix this bug.

Hi, I am also having this issue. It just seems to have stopped working after an apt-get upgrade last week sometime.

Deluge version :1.3.13-0, Python version: 2.7.6, OS: Ubuntu 14.04.5 LTS, Kernel: Linux 3.13.0-106-generic #153-Ubuntu SMP Tue Dec 6 15:44:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux WebUI: 1.3.13-0~trusty~ppa1

Having the exact same issue - waiting for status update. Rebuilt from source, and still getting error on Ubuntu 14.04.

You need to report the libtorrent package to launchpad bug tracker.

If you can also test building libtorrent from source that would be helpful

[Calum]

Actually what version of libtorrent are you using?

Deluge version :1.3.13, Python version: 2.7.6, I can't get the libtorrent version because when I check, I get this:

user@server:~$ python -c "import libtorrent; print libtorrent.version"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: /usr/lib/python2.7/dist-packages/libtorrent.so: undefined symbol: _ZN5boost4asio2ip10address_v4C1ERKNS_5arrayIhLm4EEE

I've also compiled libtorrent from source as shown in the wiki here, which is currently 1.0.10, but the issue persists.

EDIT: I reverted to a Veeam backup of my VM 13 days ago, when I know for sure deluge worked, and was able to get the python version to show libtorrent version 1.0.9.0. So, we know that works.

[Calum]

Ok thanks for checking that, I shall verify and report upstream

[kars85]

Hi Cas,

I was able to build libtorrent from source from ​http://dev.deluge-torrent.org/wiki/Building/libtorrent now that I found where I was messing up on Step 5, option 1. I was Ctrl+C'ing out of that sudo checkinstall command after entering it and it wasn't building completely. After letting it finish by hitting Enter, libtorrent built successfully and was able to launch Deluge.

Thanks for the follow-up, nonetheless. Happy New Year!

[Calum]

Good to know you fixed it.

For reference I created an upstream ticket ​https://github.com/arvidn/libtorrent/issues/1466
