Bug 1980327

I have a similar problem.

packagekitd starts flooding the logs

But i don't use byobu. I use gnome-software and I think packagekitd starts flooding after waking up from hibernate / suspend. This cause high memory usage (my notebook with 32 GB RAM and 16 GB swap) run out of memory. Stopping packagekit "sudo systemctl stop packagekit.service" release 20 GB RAM and half of swap. 

So I think, the toolings that use packagekit as backend, aren't causing the problem.



System:    Kernel: 5.14.8-250.vanilla.1.fc34.x86_64 x86_64 bits: 64 compiler: gcc v: 2.35.2-5.fc34 Desktop: Cinnamon 5.0.5 
           Distro: Fedora release 34 (Thirty Four) 
Machine:   Type: Laptop System: Dell product: XPS 15 7590 v: N/A serial: <filter> 
           Mobo: Dell model: 018W12 v: A06 serial: <filter> UEFI: Dell v: 1.11.0 date: 05/31/2021

I do not think this is a byobu problem. It is a packagekit-d problem. The solution is as follows:


### Shutting Down PackageKitD
``` bash
dconf write /org/gnome/software/download-updates false
sudo systemctl stop packagekit.service
sudo systemctl disable packagekit.service
```

This should stop packagekitd which is an unnecessary resource hog.
