What is "packagekitd" and how do I make the Software Updater stop waiting for it?
Solution 1:
PackageKit is a system made to use the distribution's software installation and update tools easier. You can read more about it here: https://www.freedesktop.org/software/PackageKit/pk-intro.html
You can stop packagekitd with the command:
systemctl stop packagekit
If, for some reason, you wish to disable it, you can use:
systemctl disable packagekit
