Failures due to "ImportError: /usr/lib/python2.7/dist-packages/libtorrent.so: ..." don't causes initd unit to crash

[Karl Richter]

Failures due to ImportErrors in the form of ImportError: /usr/lib/python2.7/dist-packages/libtorrent.so: [...], like reported in #2950 don't cause the initd unit to crash, i.e. sudo systemctl status deluged.service reports

and status active (exited) whereas the log contains

and the process crashed.

Maybe it's time for a systemd unit.

I'm using 1.3.14-0~yakkety~ppa1 from the PPA on Ubuntu 16.10.

There is a systemd unit: ​http://dev.deluge-torrent.org/wiki/UserGuide/Service/systemd

The maintainers of the official debian/ubuntu deluge packages include an init.d so you will need to ask them to change it.

I see, great!

But the initd unit still remains in running state after the failure. It's probably not worth spending too much time on it, though, since systemd has become quite widespread.

[Calum]

No-one should spend any time fixing them. They were already obsolete when upstart scripts were created and now doubly so.

[Karl Richter]

The import error was caused by remaining libtorrent-rasterbar.so.9... files in /usr/local/lib from a source installation, so the issue was unrelated to initd and systemd, but a user error.

Switching to the linked systemd units worked smoothly, thank you.
