Error: Failed to download metadata for repo 'pgdg-common': repomd.xml GPG signat

我的操作系统为Red Hat Enterprise Linux release 8.9 (Ootpa)，之前曾在电脑上安装PG数据库失败了。之后在系统上安装任何组件，都会报这个错。

yum install -y net-tools

PostgreSQL common RPMs for RHEL / CentOS 8 - x86_64    2.3 MB/s | 2.4 kB     00:00

Error: Failed to download metadata for repo 'pgdg-common': repomd.xml GPG signature verification error: Bad GPG signature

从报错信息看，和GPG signature有关。

执行yum install -y net-tools --nogpgcheck

Last metadata expiration check: 0:39:29 ago on Mon 10 Jun 2024 10:42:06 PM EDT.

Package net-tools-2.0-0.52.20160912git.el8.x86_64 is already installed.

Dependencies resolved.

Nothing to do.

Complete!

如果每条命令都要添加-nogpgcheck不太方便，

那我们进入/etc/yum.repos.d，把pg的安装repo删除 了。

删除后，安装任何组件没报错。
