我尝试通过VirtualBox(6.1.30)(Vagrant)运行CentOS 8服务器,昨天运行得还不错,但今天我尝试运行sudo yum update
.由于某种原因,我一直收到此错误:
[vagrant@192.168.38.4] ~ >> sudo yum update
CentOS Linux 8 - AppStream 71 B/s | 38 B 00:00
Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
我已经试过改变/etc/resolve.conf
上的命名空间,删除DNF文件夹和所有东西。在其他电脑上,这个操作正常,所以我认为问题出在我的主机上。我也试过重置网络设置(我在Windows 10主机上),也没有成功。这不是DNS问题;它工作得很好。
重新安装Windows后,我的虚拟机中仍然出现相同的错误。

下面的命令对我有帮助:
这样做将使DNF工作,但您将不再收到任何更新。
要升级到CentOS 8流:
如果内核已更新(在container中不需要),可以选择重新启动。

CentOS 8于2021年底停产。一个长期的解决方案是迁移到不同的操作系统,如Rocky Linux。
