Yesterday I ran a rather complicated yum install, for which I had to enablerepo=development , and today when I run "yum update" I get the error ========================================== [tim@william 2004]$ sudo yum update Traceback (most recent call last): File "/usr/bin/yum", line 8, in ? yummain.main(sys.argv[1:]) File "/usr/share/yum-cli/yummain.py", line 51, in main base.getOptionsConfig(args) File "/usr/share/yum-cli/cli.py", line 133, in getOptionsConfig self.conf = yumconf(configfile = yumconffile, root=root) File "/usr/lib/python2.4/site-packages/yum/config.py", line 227, in __init__ self._doFileRepo(fn) File "/usr/lib/python2.4/site-packages/yum/config.py", line 299, in _doFileRepo doRepoSection(self, repoconf, section) File "/usr/lib/python2.4/site-packages/yum/config.py", line 313, in doRepoSection mirrorurls = getMirrorList(mirrorlist) File "/usr/lib/python2.4/site-packages/yum/config.py", line 390, in getMirrorList fo = urlresolver.urlopen(url) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 427, in urlopen return default_grabber.urlopen(url, **kwargs) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 555, in urlopen return self._retry(opts, retryfunc, url) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 527, in _retry return apply(func, (opts,) + args, {}) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 554, in retryfunc return URLGrabberFileObject(url, filename=None, opts=opts) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 703, in __init__ self._do_open() File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 747, in _do_open fo, hdr = self._make_request(req, opener) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 823, in _make_request fo = opener.open(req) File "/usr/lib/python2.4/urllib2.py", line 364, in open response = meth(req, response) File "/usr/lib/python2.4/urllib2.py", line 468, in http_response code, msg, hdrs = response.code, response.msg, response.info() AttributeError: HTTPResponse instance has no attribute 'code' ========================================== What is the solution? (And what is the problem?) [Briefly, how I got into this position: system-config-printer did not appear to be working, so I removed it with "rpm -e" and then tried to re-install it with yum install. This turned out to require me to enablerepo development, as at some time in the past - quite a long time ago - I inadvertently updated with the development repository enabled.] Any advice or suggestions gratefully received. Ps I find yum a marvellous resource - but when it doesn't work, I find the python error messages difficult to interpret. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
