GPG key throws an error even though it is deleted

[OC VORTEKS]

After running this command (with the intent to delete the specified key):

sudo apt-key --keyring /etc/apt/trusted.gpg del F987627F

and running sudo apt update I still receive an error saying that a public key is not available for the key I just deleted. I want to stop receiving that error message and solve the root issue. Any help would be greatly appreciated.

What the heck, My eyes are not too good at reading this lol

But, deleting a key definitely is NOT going to fix a key error. Especially when we don't know what that error is.
A software repository requires one, so deleting a key probably does not fix any problems.

Please post that error message, so we can better see what is needed. With a normal black text, please
The full message very likely provides the necessary info needed, and point to a proper fix. We are looking for the added repo or PPA that this key was associated with. This is what is looking for that key

My apologies, here is the error message:

GPG error: https://dl.winehq.org/wine-builds/ubuntu kinetic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672F

so for now you wil;l need to remove the winehq repository you added

or read and follow their directions completely and fully

Winehq key problems

W: GPG error: https://dl.winehq.org/ ... NO_PUBKEY 76F1A20FF987672F

Currently, the Wine servers are being synchronized. This means that some users still getting the older .sources file. If you get this warning, edit the winehq-<distro>.sources file and replace /usr/share/keyrings/ to /etc/apt/keyrings/.

Most likely this edit is already done.
The sources file looks to have this change by default now, so editing is only necessary for previous installs, mainly for older *buntu releases.

Mirror sync in progress?

If you get an error message when trying to install a package from WineHQ that includes the line Mirror sync in progress? that is most likely the problem. There are many packages to sync, and it can take a long time to complete.

Wait a few hours, and try again. If the problem persists for more than a day, file a bug.

I suggest deleting the winehq repo, and seeing if things are OK afterward, and hold off on messing with Wine for a bit. Wine HQ is either awesome, or a steaming pile of poo in my own experience
delete the file /etc/apt/sources.list.d/winehq-kinetic.sources
Update, and see if there are errors.

I tend to recommend looking at Lutris or Bottles, or anything that uses separate non-system independent wine implementations.If those mess up, just nuke that specific app or directory, and nothing mucks with your OS.

Thank you for your assistance, I followed your instructions and I no longer receive error messages when running an update. I did still receive KGpg error messages on startup, but I did not need the program anymore so I deleted it.
