Bug reference: 18268
Logged by: Adam Smith
Email address: adam.smith@matillion.com
PostgreSQL version: 13.13
Operating system: AL2 and Centos8
Description:
We are getting failures when installing Postgres 13 with GPG enabled.
We think something has happened with the keys on your side.
warning:
/var/cache/yum/x86_64/2/pgdg13/packages/postgresql13-libs-13.13-1PGDG.rhel7.x86_64.rpm:
Header V4 RSA/SHA1 Signature, key ID 73e3b907: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG-13
The GPG keys listed for the "PostgreSQL 13 - Amazon Linux 2 - x86_64"
repository are already installed but they are not correct for this
package.
Check that the correct key URLs are configured for this repository.
We downloaded the key from:
https://download.postgresql.org/pub/repos/yum/RPM-GPG-KEY-PGDG-13
I think you've had this issue before.
Kind regards
Adam
