fedora 43

7.0.0-200.nobara.fc43.x86_64 (64-bit)

kde plasma 6.64

Cannot do updates or intsall anything from the dnf appcenter, flathubs, open external links (KIO client “could not read file magnet…”. It has been like this from fresh os install. So il go manual with console to get what i need.

I sort of updated the system from the command line but it never really updates, can do that indefinitely.

tried all sorts of things and update and “remote-add if not exists” etc commands. But no fix

I could download the new 44 version and maybe it fixes it but im too lazy to set all things up again.

There has to be some problem why it fails. I will certainly do a fresh install but why it seems unfixable now?

from dnf appcenter:

It cannot be unfixable but i cannot fix it either because i do not know the right commands which will reinstall all the buggy stuff from the command line. Everything i do from the console is successfull but nothig changes

Fedora has no “dnf app center”.

what’s the output of sudo dnf update --refresh.

You’re using Nobara. Therefore you should head to https://nobaraproject.org/ and ask there.

My guess is that nobara no longer provides updates for nobara version 43 und you should have upgraded to nobara 44 some time ogo.

Correct!

@dmix69 Nobara 43 is actually not supported anymore. As you can read in the FAQs. See point 13.

Frequently Asked Questions | Nobara Project Wiki

  1. I have an old Nobara installation I haven’t updated in over a year. Is there still an upgrade path for me to update to the latest version?

    No. Unlike Fedora, when a new version is released, the old repos are deleted within six months - I simply can’t afford to continue to pay for that much hosting space. If you don’t update to the latest version within that timeframe then you may not be able to, and the easiest solution is to back up your personal files and reinstall.
