I am trying to install Image Scan! bundle from Epson for my GT-1500 scanner. When I run ./install.sh I get the error:
W: GPG error: https://downloads.plex.tv/repo/deb public InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 97203C7B3ADCA79D
E: The repository 'https://downloads.plex.tv/repo/deb public InRelease' is not signed.
I looked into --allow-unauthenticated
but doesn't seem to work for my case.
