When updating using Discover, it has a 2.3 MiB upgrade, I restart, it installs something, then boots into Fedora 42.

You can try to add to command line:
  --allowerasing to allow removing of installed packages to resolve problems

Unsure if I should --allowerasing like the end of this command says, as it’s a huge list of problems. Unsure what the root cause of this is.

These repos probably should be disabled before attempting to upgrade.

Several of your conflicts appear to be between the fedora and the source & debuginfo repos. Those repos should only be used if you are actively doing development and need the source code.

Also, if you are not actively doing development with openh264 you should not have the openh264-devel package installed.

Those can be disabled with f42 using a command such as
sudo dnf config-manager setopt <repoid>.enabled=0.
For example to disable the fedora-source repo it would be
sudo dnf config-manager setop fedora-source.enabled=0,
and similarly for each of the listed repos above.

Just realised you meant get rid of openh264-devel package, not remove the repolist for openh264. Added it back and checked the update again, here is the new problem list:

ChatGPT 5.1 Thinking is just telling me to input this command: sudo dnf system-upgrade download --releasever=43 --allowerasing --assumeno, but last time I relied on AI it literally gave me a command that removed all my packages, so I am going to wait on a response here instead.

Edit: I got impatient and looked into each command. Seems --assumeno makes it fine to do as a test. Went to test it and got this result:

sudo dnf system-upgrade reboot

Rebooted and updated, saying it will upgrade me to Fedora 43, and when getting back into my system after the “update” my system still says this:

admin@fedora ~> cat /etc/os-release

Which is in line with there being no difference I can make out after the “upgrade” to 43. Unsure why I am not updating to 43 despite doing all this.

You can try to add to command line:
  --allowerasing to allow removing of installed packages to resolve problems

Before trying to do the system-upgrade did you do step 1 from this doc?
sudo dnf upgrade --refresh

A user should not have both openh264 and noopenh264 installed.
The post from @vgaetera just above shows one way to fix that

It seems it’s not fixing the noopenh264 problem. I am unsure why I have both installed, I think I was trying to fix codecs at one point or smth and got bad advice. It seems that the command recommended to “fix” this hasn’t fixed it for some reason. I have been running sudo dnf upgrade --refresh but this has been a problem for so long that I hadn’t done it recently and needed to. Despite that there is still issues even after doing that.

Okay I updated my flatpaks, and when trying the system-upgrade again it didn’t come up with any problems. But when updating and rebooting to install, it installed and then booted into a Fedora 42 system instead of a Fedora 43 system.

Showing it’s still Fedora 42:

Is this ok [Y/n]: n
Operation aborted by the user.

Since I already went through the upgrade process and it rebooted into a non-upgraded system, I am assuming that it being a 0 B operation would lead to the same result. It seems the codec issue is fixed though, as there isn’t any problems anymore, but now I have a new problem that isn’t being detected: I cannot upgrade to Fedora 43.

As a sanity check I went through with the 0 byte update, and cat /etc/os-release is still showing I’m on Fedora 42 as I expected. When doing system-upgraded again it gives me the exact same 0 byte update. Meaning I’m caught in a loop for some reason.

Ran your command again to see if that would fix it, and it says noopenh264 isn’t even installed. So the problems created from conflicts: noopenh264-2.5.0-2.fc42.x86_64 from fedora conflicts with openh264 provided by openh264-2.6.0-2.fc43.x86_64 from fedora-cisco-openh264 doesn’t make sense to me.

I am unsure why it even went away before. I just did a fresh upgrade and reboot.

Rechecked your other command:

Is this ok [Y/n]:

Which it’s trying to install noopenh264, despite not having it, and despite the reason I can’t upgrade being because of a conflict with this package despite not having it installed. I am unsure why my system is doing this.

Getting a USB setup with 43 on it now just in case. But I am just so confused by all of this. I can try what you’ve said, but you guys told me to fix the problems first which they haven’t been fixed, and rerunning your commands isn’t fixing it.

It appears that for some reason steam is asking for noopenh264 to be installed and the distro-sync command would have fixed the conflict.

I don’t understand why that would be but I if I might guess – :

There has been quite a bit of discussion about some regions not being able to access the fedora-cisco-openh264 repo and thus unable to update their systems. It may be that the steam packagers switched dependencies to allow those areas to be able to update their system. Normally an update requires the fedora-cisco=openh264 repo to be accessed, especially when firefox is in the picture.

Note that I have this in f43 and I have steam installed as well.

$ dnf list --installed \*openh264
Installed packages
gstreamer1-plugin-openh264.x86_64 1.26.8-1.fc43 updates
mozilla-openh264.x86_64           2.6.0-2.fc43  fedora-cisco-openh264
openh264.x86_64                   2.6.0-2.fc43  fedora-cisco-openh264

So that seems to indicate that once you have done the upgrade you probably could reinstall the 2 packages being removed and remove noopenh263.

To me it appears that the solution, at least temporarily, would be to complete the dnf distro-sync command then see if the update will complete normally. When noopenh264 is installed there are other ways to get the h264 codecs that have been coming from cisco in the past.

Going to rerun:

sudo rpm -e --nodeps noopenh264
sudo rpm -e --nodeps openh264
sudo dnf install openh264
sudo dnf check

Since I cannot seem to upgrade to 43 even after updating, syncing, installing noopenh264, and upgrading, I feel like giving up for now. It just keeps looping whenever I reboot to install 43 regardless of what I have installed or not.

If you guys know why this is happening, I’ll update, sync, install noopenh264, and upgrade again + do what I need to do to make it work, but for now my Steam doesn’t actually need noopenh264, so I’ll keep in uninstalled and just stay on Fedora 42 until I know a fix. Or maybe I’ll just do a fresh Fedora 43 if I ever need to.

Is there any reason to upgrade to 43? They keep supporting older versions of Fedora for quite some time right? Shouldn’t be an issue if I stay on an outdated distro?

Also my repolist in case I still need to do something there:

Since steam wanted noopenh264 and something else wants openh264 I would suggest that you do this in a different way.

  1. remove steam sudo dnf remove steam --noautoremove
  2. upgrade sudo dnf system-upgrade download --releasever=43 --allowerasing
    which should allow replacing noopenh264 with openh264
  3. complete the upgrade sudo dnf offline reboot
  4. reinstall steam sudo dnf install steam

That should bypass the conflict and complete the upgrade properly. Let us know if it fails and if so the point where it is a problem

There’s definitely something weird is going on.
Perhaps some packages are version-locked or excluded.

Complete the post-upgrade tasks, specifically updating configs and relabeling:
Post-upgrade tasks :: Fedora Docs

Then check for problematic packages and modified/extra configs:

sudo dnf repoquery --duplicates
sudo dnf repoquery --extras
sudo dnf versionlock list
sudo rpm -V -a
sudo find /etc/dnf /etc/yum.repos.d -exec rpm -q -f {} + | sort -u
sudo find /var/lib/rpm* -exec ls -l -d {} +
echo ${PATH}; readlink -f ${PATH//:/ }
