Akregator currently includes Kubuntu Hungary and Kubuntu Spain RSSes which do not exist anymore and gives 404. Reproducible: Always Expected Results: It will be better if we could simply remove them. Another approach will be asking on KDE Forums/Mailinglists or creating a poll to include default RSSes on Akregator.
Sorry we don't provide it. It's kubuntu which provides theses rss. Please report to them. Regards
