Comment 14 for bug 1391673

I am also getting this error with virt-install

When running the following in ubuntu 15.04;

 virt-install -n dummy -r 512 --vcpus=1 --os-type=linux
--os-variant=rhel7 -w bridge:virbr0 --disk
path=/var/lib/libvirt/images/dummy.qcow2,size=8 -l
http://pubmirrors.dal.corespace.com/centos/7/isos/x86_64/ --dry-run

I am given "ERROR global name 'fetcher' is not defined."

Enabling debug shows ( snipped output )

My python-fu is quite weak and I can't figure this out. I was able to
run
> python setup.py test_urls

Some URLs Errored, 1 failed, many passed.

The packages associated for ubuntu 15.04 are;

ii virt-manager 1:1.0.1-5ubuntu all desktop application for managing virtual mach
ii virtinst 1:1.0.1-5ubuntu all

For what it's worth. I install virt-manager 1.2 from source (required an additional library libosinfo-1.0-0:amd64 (0.2.11-1.1, automatic)) and found other errors trying to verify the source of the .iso, however, I did not get the python global name error that you get from running the ubuntu 15.04 version.

I contacted the owner of the package and was told "

I think this is an ubuntu specific bug, either a botched backport or some
broken custom patch they have, since I don't see code like that in v1.0.1
virt-manager. I'd suggest filing a bug with them"
