#3309 new bug
TypeError: '>' not supported between instances of 'NoneType' and 'str'
| Reported by: | kuraga | Owned by: | |

Description
At start:
TypeError: '>' not supported between instances of 'NoneType' and 'str'
Traceback (most recent call last):
File "/usr/lib64/python3.6/site-packages/deluge/ui/gtk3/listview.py", line 233, in stabilized
result = sort_func(model, iter1, iter2, data)
File "/usr/lib64/python3.6/site-packages/deluge/ui/gtk3/torrentview.py", line 106, in progress_sort
return cmp(state1, state2)
File "/usr/lib64/python3.6/site-packages/deluge/ui/gtk3/common.py", line 45, in cmp
return (x > y) - (x < y)
Seems like number of this messages correlates with number of torrents...

There is a related ticket #3330 which has a TypeError comparing None and None so the issue is due to string type checking by Python 3. So the cmp function needs to be able to handle either or both values being None by converting to appropriate type before comparison.

Is there any update on this?

I hoped there would be an update since this error makes Deluge 2 totally unusable however I lost hope and stick with Deluge 1.3 that it is stable and functional.

Here's a guide in how to port python 2 comparison operations to python 3.

Another person bitten by this. I don't understand how I triggered it. Deluge had been working fine, I messed some things up w/ Python then fixed that, but now Deluge won't start. Mine is more like ticket 3330 where I'm getting "TypeError?: '>' not supported between instances of 'NoneType?' and 'NoneType?'" like that user.
Is there even a workaround or hack so I can become functional again in the meantime?

I have the same error as kuraga, I report here the result of my investigation.
Problem
The list of torrents takes time to load at startup with the current version of Deluge 2.0.3 from the offical ppa deluge-stable installed for Ubuntu 18.04 Bionic.
The problem seems located in the GTK UI component of Deluge and it leads to too many open files error. It seems to be a problem of passing a null parameter to the cmp function in deluge/ui/gtk3/common.py.
I have around 60 torrents, seeded correctly with Deluge 1.3 or Transmission.
Reproduce error
After a successful fresh install of Deluge 2.0 and a first start in standalone mode without any error, I add torrents in seed manually via menu -> File -> Add Torrent everything seems right so far. Then I close and restart Deluge. It starts with an empty list of torrent and it takes several seconds to load them. It may sometimes crash at this point or just run slowly and starts to use more and more CPU ressources.
To track the problem you can watch in your system log file (personally I use journalctl) or just start Deluge in terminal and see the error.
This error is repeated houndreds of times

[ERROR ][deluge.core.torrentmanager :1132] Unable to save torrents.fastresume: [Errno 24] Too many open files: '/home/username/.config/deluge/state/torrents.fastresume.tmp'Diagnostic
I have installed the package deluge 2.0.3-2~201906121747~ubuntu18.04.1 provided by the ppa:deluge-team/stable for Ubuntu 18.04 Bionic, Python 3.6 is used to run Deluge with libtorrent: 1.1.5.0
Prior to the installation of Deluge 2.0.3, I have purged all packages related to Deluge 1.3 from the universe repository of Ubuntu: deluge deluge-common deluge-gtk and moved my ~/.config/deluge
I run the command deluge -L=debug -l=deluge_debug --profile=deluge_profile &! to report information about the bug. The following are extracts from deluge_debug that might help to track the problem.
Around line 397 and repeated sometimes in the rest of log after:
