Disable packagekitd-offline-update?

Hi to you all
I’ve recently switched to kde/plasma in Fedora 41, and while I love to use it, there are some things that do not go that well with me. One of these things that come along KDE seems to be the packagekitd / packagekitd-offline-update service : it suddenly starts to update my machine while it’s rebootìng when I never asked for that and don’t need it in the first place (I’m using dnf-automatic).
So, is there a proper way to disable it please (systemctl stop / mask ?) ? Will this cause any issue with kde ?

Note : also, I suddenly realize mariadb was removed yesterday by packagekitd and … I have no idea how is that even possible. It seems to be some actions of mine :

5:00 PM
new remove-packages transaction /13907_dbbadaed scheduled from uid 1000
5:00 PM
in /13907_dbbadaed for remove-packages package mariadb-server;3:10.11.10-1.fc41;x86_64;installed was removing for uid 1000
PackageKit

Might be related to Discover but even then, I wasn’t doing anything worth removing mariadb. And I can’t find any dnf history transaction at 5:00 PM. What do you think happened ? Automatic dependencies removal maybe ?
Thanks for you help

For gnome-software I used to do systemctl mask packagekit.service

I want to say Gnome-Software only worked for flatpaks after that but it’s been ages since I did that.

Packagekit is still using the older version of dnf so you may want to check dnf4 history to see if there’s something there.

So, systemctl mask packagekitd-offline-update it is. Done.
hmm … nice suggestion @Joe, that was it indeed :

» sudo dnf4 history info 12099

Now I think I was trying to remove knotes (i … think). Why it would also remove mariadb is beyond me. Next time when removing the zip package it will also remove podman ?
Well, either way, thank you Joe. I think using Discover for the first time is also going to be the last time.
