Managed to fix this, but was wondering if this was a common issue and why this happens
Got an error message that went something like this (I’m on Linux Mint 22.2):
8 packages can be upgraded. Run ‘apt list --upgradable’ to see them.
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. 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 0686B78420038257
W: Failed to fetch https://brave-browser-apt-release.s3.brave.com/dists/stable/InRelease The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 0686B78420038257
W: Some index files failed to download. They have been ignored, or old ones used instead.
I managed to fix it using AI (which I didn’t want to do) and if I remember correctly, it had me manually add back in the repository and delete the old one. Has anyone else run into this and why does it happen?
