Come to see you from your error message check yum configuration file path is correct

CodePudding user response:

Looks like a repo library path is wrong?

CodePudding user response:

Repository is wrong, see the Linux replace replace repository

CodePudding user response:

You this is copy other people's machines, somebody else's configuration repository is 192.168, that is to say the somebody else has a network repository, change the yum source, left on their own

CodePudding user response:

Should be the source address

CodePudding user response:

Try open ftp://192.168.1.251/big/Rpms/repodata/repomd in a browser. XML
192.168.1.251 on reading the newspaper is wrong to check yum source configuration
