I have recently installed a (Linux) Debian / Stretch Operating System, on existing hardware that I had, but an O/S version that uses Plasma 5 as its desktop manager, and that is officially a “Kanotix” build. Because Linux users often like to have the same level of comfort as Windows users, and like to be able to update and/or install software using the point-and-click method, as often as possible, Kanotix has chosen to use the GUI application “Apper” to manage software updates. This application uses the background-daemon “PackageKit”, to execute what the user told it to do, using the elevated privileges with which this background daemon runs.
But there is a known bug in this arrangement, which has just come to my attention this morning. PackageKit was polling the repositories for software updates every 5 minutes! While some people might think it’s cool, to be up-to-date about new packages, to within 5 minutes, in fact it’s not cool. And, if the repository-servers get the idea that they’re being spammed by continuous requests, they may even black-list the IP addresses that are doing so! So what can be done as a work-around, until the coders actually fix this bug?
