Hi! Get the following while running (RH ES 3.0) yum --version 2.0.7 (python version is 2.2.3) yum-arch -v /path/to/packages (lots of packages working) Digesting rpm - ... Traceback (most recent call last): File "/usr/bin/yum-arch", line 23, in ? pullheaders.main(sys.argv[1:]) File "/usr/share/yum/pullheaders.py", line 196, in main rpminfo = genhdrs(rpms, tempheaderdir, cmds) File "/usr/share/yum/pullheaders.py", line 333, in genhdrs headerloc = hobj.writeHeader(headerdir, cmds['compress']) File "/usr/share/yum/rpmUtils.py", line 236, in writeHeader headerout.close() File "/usr/lib/python2.2/gzip.py", line 258, in close self.myfileobj.close() IOError: [Errno 5] Input/output error Exception exceptions.AttributeError: "'NoneType' object has no attribute 'write'" in <bound metho d GzipFile.__del__ of <gzip on 0x82ba544>> ignored It stops with this error at different rpms and on different archs. First thought it might be related to the fact that the dirs containing the rpms are NFS mounted (rw), but that doesn't seem to be the problem, mounting with "tcp" didn't showed any change. It doesn't matter which archive is used, the genuin RH ES 3.0 install or update tree or some 3rdparty tree with rpms, always the same error. Thx for reading and any hint how to solve the problem.
