Solution pour l'impossibilité de mettre à jour CentOS 8 (mise à jour yum / mise à jour dnf) en raison des clés centos-gpg-keys existantes

problème

Impossible de mettre à jour les packages avec dnf update sur CentOS 8 sur IBM Cloud. J'obtiens l'erreur suivante:

[root@syasuda ~]# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)

[root@syasuda ~]# dnf update
Last metadata expiration check: 2:23:09 ago on Mon Sep 28 18:34:38 2020.
Error:
 Problem: cannot install both centos-gpg-keys-8.2-2.2004.0.2.el8.noarch and centos-gpg-keys-8.2-2.2004.0.1.el8.noarch
  - package centos-repos-8.2-2.2004.0.1.el8.x86_64 requires centos-gpg-keys = 8.2-2.2004.0.1.el8, but none of the providers can be installed
  - cannot install the best update candidate for package centos-gpg-keys-8.2-2.2004.0.1.el8.noarch
  - problem with installed package centos-repos-8.2-2.2004.0.1.el8.x86_64
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Cela semble être dû aux centos-gpg-keys.

centos-gpg-keys-8.2-2.2004.0.1.el8.noarch : CentOS Linux RPM keys
Repo        : @System
Matched from:
Provide    : centos-gpg-keys = 8.2-2.2004.0.1.el8

centos-gpg-keys-8.2-2.2004.0.2.el8.noarch : CentOS Linux RPM keys
Repo        : BaseOS
Matched from:
Provide    : centos-gpg-keys = 8.2-2.2004.0.2.el8

Exemple d'échec

Si vous essayez de mettre à jour avec l'option --allowerasing de force, divers fichiers dont / etc / passwd seront mis à jour, il est donc préférable d'arrêter (je pense)

[root@syasuda ~]# dnf update centos-gpg-keys --allowerasing
