CentOS - May 2020 - repomd.xml.asc BAD signature in CentOS-7-x86_64-Minimal-2003.iso

Hi list,

I downloaded the CentOS-7-x86_64-Minimal-2003.iso ( sha256sum
659691c28a0e672558b003d223f83938f254b39875ee7559d1a4a14c79173193 ) and
mount it on /mnt

Unfortunately, It returned "BAD signature" when I verified the
repodata/repomd.xml.asc

So should I continue to use this ISO?

Below is my procedure:

# gpg --import /mnt/RPM-GPG-KEY-CentOS-7
gpg: key F4A80EB5: public key "CentOS-7 Key (CentOS 7 Official Signing
Key) <security at centos.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

# gpg --fingerprint
