Virtual Machine Manager error (virt-manager) after update rpm pacakge of CentOS 7.7.
Error message:
virt-manager-1.5.0 request.py:5:<module>:ImportError:cannot impore name UnrewindableBodyError
That issue comes from installed uncorrected package combination.
So, remove urllib3 and requests package of python 2.7.
# pip uninstall urllib3
# pip uninstall requests
# yum remove python-urllib3
# yum remove python-requests
and re-install urllib3 and requests package to original package.
# yum install python-urllib3
# yum install python-requests
Now, re-install virt-manager package.
# yum install virt-manager
Now it will be work Virtual Machine Manager(virt-manager).
