courage?!?!?!
this is an online community for fedora linux not a war zone, courage is not a requisite to get help here.
asking for a solution by stating only your laptop model in the opening post is truly epic.
the banter was between hammerhead & me, you are not in the middle of anything.
A friend helped me fix this issue in person using terminal commands.
He directed me to the section "installing free and non-free repositories on this page: https://rpmfusion.org/Configuration
He walked me through enabling the free and non-free repositories for Fedora 40.
I don’t know why it didn’t work using the software repositories link on the “software” page.
I can now watch videos on all the sites.
RESOLVED
Josie, there is one big advantage in using DNF (the package manager from the terminal) to install, remove and update software on Fedora, instead of the “graphic application” Gnome Software.
Gnome Software will tell you there are “system updates” but doesn’t show the details. Instead via DNF you get the list of updated, new-installed, old-removed packages and it is very useful to be aware of what happens, when and why.
Plus, Gnome Software requires to shut down and restart the computer to install the updates, that is the safest way but personally I find it annoying.
Then, this is not for everybody of course, Gnome Software runs in background with packagetkitd and I dont’ need it, so I changed a config file in my user profile so that Gnome Software doesn’t start at boot time but only on demand.
Thank you.
Just out of curiosity, you could try “sudo dnf update” from the terminal.
It doesn’t do anything dangerous.
It just retrieves the list of available updates from the enabled repositories and it shows it.
Then it asks if you want to proceed.
You press “y” for “yes” or “n” for “not” and abort.
Overall It is exactly the same that updating from inside Gnome Software.
Then if you want to look for some software via DNF you can type “dnf search xxxx” and again a list of maching packages is displayed.
To install (or remove) you type “sudo dnf install xxxx” or “sudo dnf remove xxxx”.
Sounds easy to me
