dockerでpostgresをインストールしようとしたら

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

なにこれ？？

調べるとPGDGをアップデートしないとこのエラーが出るらしい

今のバージョン確認

[root@91363d2a1494 /]# rpm -qa | grep pgdg
pgdg-redhat-repo-42.0-38PGDG.noarch

最新は0-54らしい

アップデートする

dnf –disablerepo=* -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm

これでもう一度postgresインストールしてみる

yum -y install postgresql*

成功した！！
