PPA Signing key is wrong

Asked by pchainorg on 2019-01-18

I upload my PPA:https://launchpad.net/~pchainorg/+archive/ubuntu/hello
I sign the package with pgp info below:

pub 2048R/F364467E 2019-01-17
      Key fingerprint = 5DBC 3382 ACA3 6C95 5E45 4366 19BB FA22 F364 467E
uid pchainorg <email address hidden>
sub 2048R/796DE212 2019-01-17

but when i open the PPA link: found another singing key,as below

Signing key:
    4096R/4A7475E191AC1BC3161559E53F26A26C61FF97F3 (What is this?)
Fingerprint:
    4A7475E191AC1BC3161559E53F26A26C61FF97F3

why this happen?

when i add my own ppa in ubuntu: sudo add-apt-repository ppa:pchainorg/hello
I got the error:
gpg: keyring `/tmp/tmpd8dhsfvv/secring.gpg' created
gpg: keyring `/tmp/tmpd8dhsfvv/pubring.gpg' created
gpg: requesting key 61FF97F3 from hkp server keyserver.ubuntu.com

gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

why this happen? where the 61FF97F3 from?

The PPA official will give a new key to sign package.
and the package will work after a few minutes when you uploaded your package
