it’s happening to me too…

could you please do:

dnf clean all

and start update again

Regards.,

grumpey · May 11, 2019, 1:15pm

I was able to update after doing dnf clean metadata

This seems to happen to me when I don’t do anything with dnf for a few hours or have the machine shut off overnight.

Thanks

I have the next debug info from “sudo dnf upgrade” with dnf version 4.2.5-1.
This is after “sudo dnf clean all”.
If I disable the updates-modular repo everything goes normal.

Setting zchunk=False in /etc/dnf/dnf.conf also seems to work. This would need to be set back after this is corrected.

gzmorell · May 15, 2019, 10:07am

I can confirm using “zchunk = False” in /etc/dnf/dnf.conf works for me.
If I remove “zchunk = False” the error comes back again.

grumpey · May 15, 2019, 9:58pm

If anyone is using max_parallel_downloads=1 you may want to try removing it or changing it to 2. (believe it defaults to 3)

ankursinha · May 16, 2019, 7:31am

Is your system up to date? There were zchunk related issues before the release but they were fixed.

grumpey · May 16, 2019, 10:59am

Yes it is, it’s this https://bugzilla.redhat.com/show_bug.cgi?id=1706627

FYI, I usually set that because my internet isn’t the greatest and multiple downloads end up timing out.

hhlp · May 16, 2019, 11:39am

for me setting fastestmirror=false in dnf.conf did the trick, if I’ve got error execute dnf clean all or retry and problem solved whithout touch zchunk that was introducing in 30 to reduce the compression and performance in dnf.

Regards.,

ralmeida · May 17, 2019, 5:02pm

great!! works fine …now… thnx

hhlp · May 23, 2019, 7:10pm

The fix is in update-testing you can do:

sudo dnf update --enablerepo=updates-testing dnf\* zchunk\* librepo\*

you can test it and provide karma with your fas → https://discussion.fedoraproject.org/t/how-can-i-test-updates-and-provide-karma/61065

NOTE

don’t forget to reverse changed in /etc/dnf/dnf.conf after that
