Sorry for the angst.
I tried:

which worked because I had added other repos. It also worked without complaint with urpmi, which used an added repo.

It is possible that your repos are not correctly defined. Please post the O/P of:
 $ inxi -r | grep -v yum

Mirrorlist is a mystery to me, CC'ing Aurélien who probably knows more. We need to judge whether it is a 'mirror' problem, or DNF.

Hi,

FYI, I have not changed anything on the repo list after the install.

 $ inxi -r | grep -v yum

Comment 3 Jani Välimaa 2021-01-22 17:12:30 CET

The issue is in our infra. Directory/file permissions are fcked in main mirror and thus repodata doesn't get updated.

Comment 4 Jani Välimaa 2021-01-22 17:58:17 CET

The issue should be fixed now. Please test again in a while after mirrors gets synced.

Comment 5 Lewis Smith 2021-01-22 20:02:47 CET

Thanks Jani for your explanation.

@christian : if you find later that the problem has gone, please report back here (& close the bug 'fixed' if you like).

Comment 6 christian barranco 2021-01-22 20:14:24 CET

I am trying but without success so far. 
I will try again tomorrow. Mirrors will have had then the chance to update.
I will report and change status.

Hello,

After a test this evening, I confirm having the same bug with DNF as Christian.

I see that the terminal output shows Cauldron sources, as well as Mageia 8 sources.

Hi
Just tested. 
It has improved for nonfree and tainted.
However, I still have the issue for 'mageia-x86_64' and 'updates-x86_64'

Comment 9 christian barranco 2021-01-23 18:48:29 CET

Ok,just tested and it works now.
Thanks!

urpmi works fine !!

Comment 11 Lewis Smith 2021-01-24 14:45:34 CET

Can you both try say at the end of the month; the mirror problem was apparently still lurking after this bug was closed.
If it still persists, please re-open it.

Comment 12 christian barranco 2021-01-24 21:17:20 CET

Will do.

Comment 13 christian barranco 2021-02-08 09:09:37 CET

Hi
Just tried on a fresh install made 1 week ago (with beta2 iso) and up to date with urpmi --auto-update.
No more issue on my side.
