qBittorrent doesn't run anymore.

[Jerfus]

This is a problem which just began yesterday, prior to that it was working perfectly. Everytime I try to run it, it just shows the splash screen for a few seconds and then nothing, I've already checked and there's no process running, it doesn't open at all.

Thanks, but I had already tried that without much hope. It doesn't even open to tray, and I even tried with the grep | lsof -torr i and no process is running, neither there nor through the system monitor.

I have the same problem. A splash screen pops up for a few seconds and then it dies UUugggghh  This happens from time to time with older Ubuntu Distros.aswell. Currently using Oneiric 11.10 64bit  Help !!!!!!  Ok this is what terminal said  ----> Couldn't set environment variable...
qbittorrent: symbol lookup error: qbittorrent: undefined symbol: _ZN10libtorrent7sessionC1ERKNS_11fingerprintEii      ok My Solution was  to remove libtorrent-rasterbar 6 from synaptic package manager. Reinstalled qbittorrent from site not Software Center. It came back Hoooray !!!!

I have the same problem on the same OS (Ubuntu 11.10 64bit).

Has anyone found a fix or workaround?

This bug report led me to believe there was a problem with libtorrent-rasterbar6 from having qBittorrent and Deluge both installed.

I fixed the conflict by:

Code: Select all

sudo apt-get remove libtorrent-rasterbar6 deluge qbittorrent
sudo apt-get autoclean
sudo apt-get install deluge qbittorrent

Thank you for the tip but it didn't work, it's the same as before.

[freddybob]

Maybe it's not libtorrent-rasterbar6 causing the conflict on your system.  I'd try removing then re-installing libtorrent*.

Do you have both qBittorent and Deluge installed?  Do you need both?

[loki]

Another thought, if you do have both installed, is it possible qbittorrent and deluge are both requesting a different version of libtorrent? So one is causing a conflict with the other.
