我正在尝试安装Snap 商店和八度在 RHEL7 上官方指令。
但是，命令yum update因出现错误而卡住了，提示为https://cdn.redhat.com/content/e4s/rhel/server/7/7Server/x86_64/optional/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found。
我尝试了以下尝试进行故障排除，但没有帮助。
- 跟随https://access.redhat.com/articles/1320623
- 设置
sslverify=false在文件中/etc/yum.conf - 使用浏览器访问该链接，结果显示“访问被拒绝”https://cdn.redhat.com/content/eus/rhel/server/7/7Server/x86_64/optional/os/repodata/repomd.xml
最终我尝试了yum-config-manager --save --setopt=rhel-7-server-e4s-optional-rpms.skip_if_unavailable=true，并且有帮助。
我想知道我在上述步骤中遗漏了什么，并且我希望修复错误并正确设置所有 YUM 存储库。
如有任何提示或建议我将不胜感激。
