Re: [Spacewalk-devel] type error when trying to register an ubuntu 12.04 system

Tue, 03 Jul 2012 12:22:45 -0700

Ok i have found the problem i guess but i'm not sure what the right way would be to fix this. 

the problem is in the debUtils.py file:

def installTime(pkg_name):
    path = '/var/lib/dpkg/info/%s.list' % pkg_name
    if os.path.isfile(path):
       return os.path.getmtime(path)
    else:
#       print pkg_name printing wrong package names
       return None
I have a few packages which don't have the file with that name in the /var/lib/dpkg/info directory. 
e.g.
e2fslibs is installed:
ii e2fslibs 1.42-1ubuntu2 ext2/ext3/ext4 file system libraries 

which has the corresponding list file
ls /var/lib/dpkg/info/e2fslibs\:amd64.*
e2fslibs:amd64.list e2fslibs:amd64.md5sums e2fslibs:amd64.postinst e2fslibs:amd64.postrm e2fslibs:amd64.shlibs e2fslibs:amd64.symbols
so should the function be updated to look for e2fslibs:amd64 or i386 or is the package name just false and should this be updated (file bug report to ubuntu about the name)? thats about 422 packages on my current desktop. But this is about the installtime so we could also return just 0 or epoch?

Willem

Hi,

After commenting out:
    def dump_nil (self, value, write):
        #if not self.allow_none:
# raise TypeError, "cannot marshal None unless allow_none is enabled" 
        write("<value><nil/></value>")
    dispatch[NoneType] = dump_nil

in /usr/lib/python2.7/xmlrpclib.py it works.
So i'have no idea what it could be but maybe it helps :) narrowing the problem down.

Hi,

i have installed the packages for debian sid on my ubuntu 12.04 install.
When trying to register the system to spacewalk 1.7 or 8 running on fedora 16 i get a type error:

The system is still registered but i have no package information
When adding the system with the option --nopackages it does not give me the error and the system also registers. 

These are the packages i installed:
ii python-rhn 2.5.52-1 Python libraries for the RHN project ii rhn-client-tools 1.8.9-1 Red Hat Network Client Tools 
ii  rhnsd 4.9.15-1                                Red Hat Update Agent
