今天安装Wget时出现如下错误
到 /etc/yum.repos.d/目录下编辑CentOS-Base.repo ,更改为如下内容。
vim CentOS-Base.repo
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-8.5.2111 - Base - mirrors.aliyun.com baseurl=http://mirrors.cloud.tencent.com/centos/$releasever/BaseOS/$basearch/os/ gpgcheck=0 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official #additional packages that may be useful [extras] name=CentOS-8.5.2111 - Extras - mirrors.aliyun.com baseurl=http://mirrors.cloud.tencent.com/centos/$releasever/extras/$basearch/os/ gpgcheck=0 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official #additional packages that extend functionality of existing packages [centosplus] name=CentOS-8.5.2111 - Plus - mirrors.aliyun.com baseurl=http://mirrors.cloud.tencent.com/centos/$releasever/centosplus/$basearch/os/ gpgcheck=0 enabled=0 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official [PowerTools] name=CentOS-8.5.2111 - PowerTools - mirrors.aliyun.com baseurl=http://mirrors.cloud.tencent.com/centos/$releasever/PowerTools/$basearch/os/ gpgcheck=0 enabled=0 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official [AppStream] name=CentOS-8.5.2111 - AppStream - mirrors.aliyun.com baseurl=http://mirrors.aliyun.com/centos/8-stream/AppStream/$basearch/os/ gpgcheck=0 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official
继续修改 CentOS-AppStream.repo root 下执行命令 vim CentOS-AppStream.repo
#CentOS-AppStream.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.
