Every now and then, when the Oracle Linux yum server is in the process of being updated with new packages, you may encounter an error like the following:

 

$ sudo yum install -y yum-utils

ol7_UEKR4                                                   | 1.2 kB  00:00:00    

ol7_latest                                                  | 1.4 kB  00:00:00    

(1/5): ol7_UEKR4/x86_64/updateinfo                          |  69 kB  00:00:00    

ol7_latest/x86_64/updateinfo   FAILED                                          ETA

http://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/repodata/updateinfo.xml.gz: [Errno -1] Metadata file does not match checksum

Trying other mirror.

 

Usually, clearing the local metadata caches with yum clean will fix this issue.

 

$ sudo yum clean all
