This should now be resolved if you run apt update again.

We accidentally used the wrong key (they one we are planning to switch to early next year) to sign the repository and so that’s why you saw that error message.

HI, please forgive a newbie to Brave on Linux.
after receiving the message wrt to no pubkey I ran the following:
¨apt update
…
W: GPG error: https://brave-browser-apt-release.s3.brave.com stable InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 4FE13824E3FFC656
E: The repository ‘https://brave-browser-apt-release.s3.brave.com stable 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.
"
any idea what I did wrong?
again my apologies if this is already solved.
thanks

That second error message tells me that you need to run through all of the installation steps again.

The problem is that your system is missing the key that Brave uses to sign releases and so your system is unable to verify the authenticity of what it would download from us.

This step of the instructions I linked to above is what will install the key on your system:

curl -s https://brave-browser-apt-release.s3.brave.com/brave-core.asc | sudo apt-key --keyring /etc/apt/trusted.gpg.d/brave-browser-release.gpg add -

Once you have all of this in place, you’ll be able to install and update Brave without problems.

Let me know how that goes.

Hm, you seem to be using an old version of the instructions. Are you looking at https://brave-browser.readthedocs.io/en/latest/installing-brave.html#debian-9-ubuntu-14-04-and-mint-17? If so, try refreshing the page. If not, what page did you find the instructions on?

The third step should be this:

echo "deb [arch=amd64] https://brave-browser-apt-release.s3.brave.com/ stable main" | sudo tee /etc/apt/sources.list.d/brave-browser-release.list

Note that there is no lsb_release -sc anymore.
