For the last few days or so, when I've attempted to perform a "yum update", the process has consistently failed. The most common error is "[Error -1] Header is not complete", which is what I get after I download all 100% of an RPM from an HTTP site. When yum retries from another mirror and the mirror happens to be an FTP site, I get other errors (such as 500 RE*T not understood" or "500 Unknown command"). Poking around, I've seen an explanation for the "Header is not complete" error that indicated that there is a problem with a proxy server between me an the outside world. While I won't rule that out, I can say that I can use wget to fetch the rpm manually -- from a cursory look, the RPM seems fine to me. Any suggestions? Yes, I've tried $ sudo yum clean metadata and $ sudo yum clean all Strangely, however $ sudo yum clean cache Returns an error: Error: invalid clean argument: 'cache' despite the fact that the man page claims "yum clean cache" should work (and has worked in the past with older versions of yum). If I were to fetch an RPM manually, could I verify that it is correct somehow and then place it someplace at which yum would be happy with it? --wpd
