Capturebot seems broken by the maintenance
I'm not sure if it's capturebot's fault or changes Toulouse made, but it doesn't successfully manage to get images up to the wiki. I poked it a bunch to try and work out what was going on, in case this helps. It will happily listen for its console, however, so I know it's online.
The pywikipediabot script probably needs to be updated. The config needs to be changed (you have to explicitly specify the version of MediaWiki of the wiki the bot is running on, which is stupid because it can detect the correct version and it complains if it's not the same in the config, but whatever).
