You mean while using the dnf command, right?
But isn’t zchunck disabled?
yes, it is, just checked…
Btw I suspect that zchunk is involved in the MD_TYPE_PRIMARY has failed error.
Again, I don’t have enough knowledge on this topic, but if you look at the content of this URL https://fedora.mirror.garr.it/fedora/linux/releases/32/Everything/x86_64/os/repodata/, there are files called like something-primary.xml. zck , as well as in the destination directories /var/cache/PackageKit/32/metadata
Just to track the issue, could you show the content of /etc/dnf/dnf.conf
And what kind of error related to zchunk you get?
Oh boy! As far as I can see, even if the repositories are disabled, it seems that pkcon -v refresh force refresh them as well.
This is an interesting command to launch:
sudo /usr/libexec/packagekit-direct -v refresh-force
It gives more information about PackageKit cache refresh operations.
this is the dnf conf file

gpgcheck=1

this is the zchunk error

I think that it could be interesting to add the packagekit-direct result to the bug report.
done, hope someone will have a look at it…
Again out of curiosity, if you perform the download with curl
cd ~/Downloads
curl -O http://fedora.mirror.garr.it/fedora/linux/releases/32/Everything/x86_64/os/repodata/b7e1566c87075299c4a199737b341e7d15fbf1a4d49c4c2cbe43368437b02c47-comps-Everything.x86_64.xml.zck
Does it work? (I bet yes)
yes does it work without problem
I have another, maybe stupid, question: what about disk space?
df -h
plenty…well sort of

I was performing some test.
I used my mobile phone via usb tethering in order to connect my PC to the internet.
I don’t get the loading of MD_TYPE_PRIMARY has failed error. But when I issue the pkcon refresh force command, after a lot of time, I get an already mentioned error:
Fatal error: cannot update repo 'fedora': Yum repo downloading error: Downloading error(s): repodata/b7e1566c87075299c4a199737b341e7d15fbf1a4d49c4c2cbe43368437b02c47-comps-Everything.x86_64.xml.zck - Download failed: Curl error (23): Failed writing received data ...
If I reconnect the PC to the WiFi network, all works as expected.
Wait!
I was using an outdated system. I upgraded it with dnf.
Now if I perform the same command pkcon refresh force as before, using the mobile line, now I get
Fatal error: loading of MD_TYPE_PRIMARY has failed
Yay!

@247, I mean that probably a fresh installation of Fedora will not solve your issue.
well that means that something changed in fedora, because was not having this issue weeks ago
i do think at this point, there’s not much we can do…
Hey @247, I have another test for you 
Could you please edit again these two files?
/etc/yum.repos.d/fedora.repo
/etc/yum.repos.d/fedora-updates.repo
In /etc/yum.repos.d/fedora.repo, in the [fedora] repo-id stanza, comment all the metalink and baseurl lines. Then add this line:

In /etc/yum.repos.d/fedora-updates.repo, in the [updates] repo-id stanza, also comment all the metalink and baseurl lines. Then add this line:

Then, maybe it is pointless, issue this command
sudo rm -rf /var/cache/PackageKit/32/
and reboot.
Afterwards, open a terminal, and again, issue this command:
pkcon -v refresh force
done, things hasn’t changed by a single bit…
Weird things.
As said, this issue happens to me as well using tethering with the mobile phone. Using dl.fedoraproject.org instead of a mirror seemed to work.
