On Debian / Ubuntu, if I do apt search, I get a useful output of packages that match my search with results that look like this:
yubikey-val/stable,unstable 2.38-2 all
One-Time Password (OTP) validation server for YubiKey tokens
I understand how most of these fields are populated. However, what does stable,unstable mean and how does it get populated?
I have some custom packages that I publish to my own debian repository on S3, and these all say unknown,unknown (occasionally unknown,unknown,now).
