2020.09.25
My operating system is Ubuntu 20.04
When I update (in Terminal, using < sudo apt-get update > - all my apps and packages update fine, except for Brave - get the following message:

The following signatures were invalid: EXPKEYSIG 4FE13824E3FFC656 Brave Software
Reading package lists… Done
W: GPG error: https://brave-browser-apt-release.s3.brave.com focal InRelease: The following signatures were invalid: EXPKEYSIG 4FE13824E3FFC656 Brave Software [email protected]
E: The repository ‘https://brave-browser-apt-release.s3.brave.com focal 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.

Tried the following suggested solution:
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 -
but did not work.

Any help would be greatly appreciated.
Sincerely

sudo apt-key adv --keyserver hkps://keyserver.ubuntu.com --refresh-keys

I am providing you with the master solution.Type this command and then update the browser or best reinstall it. If it doesn’t work please feel free to tell.

Here are two things to check:

  1. Can you access https://brave-browser-apt-release.s3.brave.com/brave-core.asc in a different browser? It should trigger a file download.
  2. What is the output of sudo apt-key list?

Are you saying “it didnt work” to mean

a) the "curl … " (piped command to apt-key) did not work, i.e., it failed
or
b) the "curl … " (piped command to apt-key) DID WORK, but it didnt fix the update issue.

Many thanks for your reply fmarier - much appreciated.
I’m afraid I had spent so much time on this problem without finding a solution that I just abandoned Brave - uninstalled it - THAT solved the problem.
Thanks once again for your response.

Thanks for your reply.
Option " b) " applied.
However, I had spent so much time on this problem that I gave up and uninstalled Brave - all OK now.
Sad to lose Brave, but there you have it.
Thanks once again for your help.
