I wouldn&#x27;t say &quot;once a day&quot;. When I&#x27;m sick, I might not touch my PCs for a week, and that has always been fine.<p>The only situation where things were fucked up badly was when the system upgrade failed on a friend&#x27;s notebook that was not updated for 6 months. I had to uninstall KDE in order to untangle the missing dependencies, then do the upgrade, then reinstall KDE.
