I use the Weather Applet on Xubuntu Natty (the repository version, 0.7.4-0). A few days ago it stopped working and always shows "No data" (with mouse-over text "Cannot update Weather data"). I tried re-installing it, but to no avail. The chosen location is "Berlin, Germany", but I also tried selecting different locations and they don't work, either. I don't have any problems with my Internet connectivity otherwise. I hope somebody can help my, I really would love to have my nice little Weather Applet back :-(
