On April 18, 2021, Debian 10 updated xfce4-weather-plugin with patch +deb10u1 to fix the broken API key for communicating with the Norweigian meteorological institute servers. Here is their note in the changelog: https://metadata.ftp-master.debian.org/changelogs//main/x/xfce4-weather-plugin/xfce4-weather-plugin_0.8.10-1+deb10u1_changelog

Currently, PureOS is one version behind. Would it be possible to update to get xfce4-weather-plugin functional again, please?
