I try to update my KDE Neon Linux Ubuntu 18.04 distribution to a newer one, preferably 22.04 but when I run sudo do-release-upgrade it tells me

Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.

And when I then run sudo apt-get update to update all packages it fails with the following output

Get:10 https://dl.winehq.org/wine-builds/ubuntu bionic InRelease [6'263 B]       
Err:10 https://dl.winehq.org/wine-builds/ubuntu bionic InRelease
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672F

W: GPG error: https://dl.winehq.org/wine-builds/ubuntu bionic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672F
E: The repository 'https://dl.winehq.org/wine-builds/ubuntu bionic InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Couldn't find a specific solution for my problem, can someone point me in the right direction?

Only Ubuntu and official flavors of Ubuntu (https://ubuntu.com/download/flavours) are on-topic here, refer to https://askubuntu.com/help/on-topic where you'll find other SE sites where you question will be welcome if you don't want to use a KDE/Neon forum. *KDE Neon and Kubuntu do share some support sites, alas this is not one of them*

Looks like you missing wine's public key. Make sure you have a /usr/share/keyrings directory first.

Then try this:

sudo wget -nc -O /usr/share/keyrings/winehq-archive.key https://dl.winehq.org/wine-builds/winehq.key

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
