KDE neon users may want to reinstall
The KDE Project has a little
problem to report for users of the KDE
neon distribution: "The package archive used by KDE neon was
incorrectly configured allowing anyone to upload packages to it. There is
no reason to think that anyone actually did so but as a precaution we have
emptied the archives and removed ISOs built before this date." Once
the process of rebuilding the archive is complete, users are recommended to
upgrade to the new versions, or, better, simply reinstall.
