Fedora 23 updates causing wasted bandwidth

asked 2015-11-30 00:20:31 -0500

HISTORY: I installed Fedora 23 on a spare laptop for my brother. Sent it to him. He uses Verizon wireless Internet through a wifi hot spot. His data bandwidth limit is 12GB / month. He burned through more than 20GB in one month. Pretty expensive for someone on a very limited income.

I couldn't believe it could possibly be Fedora causing the trouble. He swore he never used more than 3GB.

REPLICATE THE PROBLEM: I installed a default workstation Fedora 23 on a Virtual Box virtual machine. Upon first boot I installed nload from root terminal:

sudo -i
dnf install nload

Using nload, I immediately see massive bandwidth usage. The computer should be sitting idle.

TROUBLE-SHOOTING: I suspected that updates were being downloaded. I ran updates to see if the usage would stop once updates were completed:

sudo -i
dnf update

Sure enough, about 720MB of downloads. Once they were completely downloaded, nload shows that there is no activity on the network.

RESULTS: I called my brother and walked him through updating the computer. His machine downloaded ~800MB of updates. His problem ended right there.

Since then he has been using about 30MB per day. He, now, updates manually every day.

This is all fine... except; how did 20GB get used in one month!?

My Theory: Looks like Fedora 23 default workstation is downloading updates in the background and then not saving them upon computer poweroff, possibly causing daily re-downloading of those same 800MB of updates.

I haven't yet tried the suggestions presented in the post: How to turnoff automatc updates in fedora 21?

My questions: I would never have noticed this in-efficiency as I have nearly unlimited download bandwidth.

Does ANYONE have any idea if this is a known Fedora23 problem? Or, where should such a problem be reported?

I do not think, its the Fedora updates that consumed 20GB. I installed F23 when it was released and started using internet with less than 1GB of data left in my account (I have a monthly limit of 3GB). Later on it downloaded ~700MB as update upon a dnf update. I also noticed that, when I interrupted a dnf update and when later resumed, it started downloading from where it stopped instead of downloading the whole update once again. Yours could be an isolated issue! Also install iftop

GNOME Software does download updates in the background. You should likely file a bug report against it.

Thank you, for your suggestion. I am, now, digging down the gnome rabbit hole. It seems that its auto update features don't really work as intended with Fedora. I have been trying to figure out how gnome automatic updates are configured, how it stores automatic downloads, and if it keeps what it downloads upon restarting the computer.
