Is KVM illegal now in F37?

I dont understand that since I upgraded to F37 from F36, everything has broken down.
I cant even do USB installation, because of uefi error. I guess my pc became illegal.

Now KVM is illegal. Why is KVM illegal in F37 now?

The screenshot here:

In what world does a failure of a dnf command equate to KVM illegal?

You used imagure instead of actually embedding the image here, so I cannot enlarge that image and closely view the actual command line that failed. It almost appears as if the i in install is not an i at all.

If you actually have a problem and wish to have assistance then please read #start-here to see what type of info we need. Provide enough detailed information about the problem and an actual request for assistance and we will be glad to assist.


I also do not understand. Is there a translation error, perhaps? Can you explain what you mean by “illegal”?

Something is also strange with the sudo dnf error message — as is if the space is not actually a space.

I think we need a lot more background detail here, please, so we can help you.

By pure chance: did you follow this guide?

Indeed, copy&paste this command sudo dnf install libvirt-devel virt-top libguestfs-tools guestfs-tools from such page, throws bash: sudo dnf: command not found also for me.
So it looks like there is some strange (hidden) character in that string.

The copy and paste did give me something like this the first time I copied it from that site but I was not able to repeat that with later attempts.
~[[200~sudo dnf install libvirt-devel virt-top libguestfs-tools guestfs-tools~

Note there are strange characters at beginning and end. They showed up in the terminal when pasted in.
When I delete those characters the command does not give a similar error.

At times I have noted similar artifacts when copying from a web page, but since the characters have always been visible have never had an issue and always deleted the extraneous characters.

Nice detective work! :slight_smile:

This actually is a good thing to keep in mind… here, it is (probably) harmless even though confusing and annoying. But it is actually possible to hide malicious code in this way — something that looks like an innocent command in a web page, but which actually hides a command which does something bad.

That isn’t possible with the way this site works (as long as you trust the admin, which I hope you do!), so commands we provide here should be okay — but it’s good practice to type anyway. Or, if is something long and complicated, don’t post directly to a terminal but into a text editor, so you can see what you’re really getting. (That might not reveal the strange space character used here, but would show any malicious code.)

Here’s a demo of what a site might do: Copy-Paste from Website to Terminal

And that the strange character is non-breaking space.
