在升级到 Stream 之前尝试更新我的 CentOS Linux 8 堆栈

CentOS Linux 8

[root@den yum.repos.d]# cat /etc/os-release
NAME="CentOS Linux"
VERSION="8 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="8"
PLATFORM_ID="platform:el8"

CENTOS_MANTISBT_PROJECT="CentOS-8"
CENTOS_MANTISBT_PROJECT_VERSION="8"

REDHAT_SUPPORT_PRODUCT_VERSION="8"

[root@den yum.repos.d]# uname -r
4.18.0-147.5.1.el8_1.x86_64

修复无法下载存储库“AppStream”的元数据的问题

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

下载存储库“extras”元数据时出错

百胜

yum clean all
yum update -y
yum check-update

yum update -y

关于如何诊断和解决此问题有什么指示吗？

答案1

从 CentOS 8 切换到 Stream 8 的说明隐藏在下载页面

# Converting from CentOS Linux 8 to CentOS Stream 8                               
dnf --disablerepo '*' --enablerepo extras swap centos-linux-repos centos-stream-repos
dnf distro-sync

升级交易即使没有完全更新也可以进行。

不要启用仅用于存档的保险库。保留它的安装会鼓励使用过期软件的不良做法。

显然 extras repo 存活了 8 年，并且 Stream（和 SIG）的发布包就存放在这里。

CentOS-Base.repo 已“损坏”

搞乱了 CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the

# remarked out baseurl= line instead.
