Howdy, This traceback might be a problem on the machine's end, and not yum. I just need a little pointing in the right direction. The problem is on a 7.3 machine, with rpm 4.0.4, python 1.5.2-38, and as far as I can tell, pretty much like any other machine. It is a laptop, if that has anthing to do with anything. Here is the traceback # yum update Gathering package information from servers Getting headers from: Fermi Linux 73rolling main Getting headers from: Fermi Linux 73rolling updates Finding updated packages Downloading needed headers Resolving dependencies Traceback (innermost last): File "/usr/sbin/yum", line 24, in ? yummain.main(sys.argv[1:]) File "yummain.py", line 201, in main File "nevral.py", line 219, in resolvedeps File "nevral.py", line 69, in getHeader File "clientStuff.py", line 167, in readHeader File "/usr/lib/python1.5/gzip.py", line 150, in read self._read(readsize) File "/usr/lib/python1.5/gzip.py", line 201, in _read uncompress = self.decompress.flush() zlib.error: Error -5 while decompressing # # rpm -q yum rpm rpm-python gzip yum-0.9.2-1f5 rpm-4.0.4-7x.18 rpm-python-4.0.4-7x.18 gzip-1.3.3-1 # rpm -V yum rpm-python gzip # # rpm -q python python-1.5.2-38 # rpm -V python # Any idea's where to start looking to fix this?
