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@example.com
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.
