Hi Seth and all, I've got a weird bit of behavior (weird to me, anyway, though I'm getting what must look to someone like a sane error message) after an upgrade of an RH9 box to Fedora Core 1 via yum. I started getting this error from yum: [root@oppenheimer root]# yum update Gathering header information file(s) from server(s) Server: Fedora Core 1 - i386 - Base Traceback (most recent call last): File "/usr/bin/yum", line 60, in ? yummain.main(sys.argv[1:]) File "yummain.py", line 188, in main File "clientStuff.py", line 766, in get_package_info_from_servers File "clientStuff.py", line 103, in HeaderInfoNevralLoad ValueError: unpack list of wrong size So I decided (brilliantly, if I do say so myself), to delete the /var/cache/yum/* directories. This has worked in the distant past when yum has had corrupted bits and complained about them, so I figured it would work again. Alas, it was not to be. Now I get the following: [root@oppenheimer yum]# yum clean all Gathering header information file(s) from server(s) Server: Fedora Core 1 - i386 - Base Error - /var/cache/yum/base/header.info cannot be found Please run yum in non-caching mode to correct this header. This looks like very sane and sensible advice. But my yum and yum.conf man pages have nothing about a non-caching mode, and a web search only turns up a snippet of a clientStuff.py patch with nothing about enabling this illusive mode. The yum --help mentions the -C switch for enabling caching, but that doesn't seem the right solution since yum is telling me to do the opposite. Anyone have a clue they can lend me? BTW-The yum is version 2.0.4-2 as it comes from Fedora. Thanks! -- Joe Cooper <joe@xxxxxxxxxxxxx> Web caching appliances and support http://www.swelltech.com
