When I try to install:
yum -y install openssh-server samba-client unzip
http://public-yum.oracle.com/repo/OracleLinux/OL5/latest/x86_64/repodata/primary.xml.gz: [Errno -1] Metadata file does not match checksum
Trying other mirror.
Error: failure: repodata/primary.xml.gz from el5_latest: [Errno 256] No more mirrors to try.
I suggest to review the following posts:
public-yum ol6_latest Metadata file does not match checksum
yum repository. checksum no match
If you try again later it will probably work.
