Exclamation virt-manager - No module named gi.repository


Greetings!

I had virt-manager working great, until I installed pygobject3 from SBo. Now, I am getting the following error upon start up:
Code:
Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-manager", line 30, in <module>
    from gi.repository import GObject
ImportError: No module named gi.repository
I'm thinking something is not playing nice between pygobject and py3cairo, but I can't quite put my finger on it. I've done some google searches already, but haven't found anything that would work yet. Hopefully someone here can be of better help. Thanks!

Which one? Virt-manager? I have. I've tried both the latest stable and git version. No changes. I'm having a hard time pinpointing what broke it.

Code:
vte3
vala
spice-protocol
pyparsing
celt051                       
spice                          
libcacard
spice-gtk
gtk-vnc
pygobject3
urlgrabber
ipaddr-py
tunctl

Yes, I got all of those already. Everything was working correctly. I have gone through the process of rebuilding virt-manager without success. I'm wondering if I need to rebuild something else.

Building pygobject3 from SBo is successful. When I try to build it using the msb git repo (older version), it fails with the following:
Code:
libtool: install: warning: remember to run `libtool --finish /usr/lib64/python3.4/site-packages/gi'

I've tried using the latest version that doesn't require a newer glib. Those compile, but still have same issues with virt-manager.

What version of pygobject3? I seem to recall that the current libvirt version required an update to pygobject3 (which was pushed to SBo, so it should be there, but make sure you have that version).

Also, for usb passthrough to work, you need a newer libusb than what's in Slackware 14.1 -- get it here: http://www.slackware.com/~rworkman/libusb/

Currently, I have (3.10.2) of pygobject which is the latest version provided on SBo. I'm running a slightly older version of libvirt, so I'm upgrading that at the moment.

it seems that you have Python3 installed. I have added a note in the README that if python3 is installed, you will need additional dependencies: gnome-common and py3cairo

I just rebuilt every single dependency and I'm still having the same problem. Where you able to build py3cairo from SBo? I had to remove the second patch file in order to get it to build.

Now that I think about it, I'm going to go ahead and remove python3 and rebuild pygobject3 again.

Ah, it appears that python3 is the culprit. I rebuilt pygobject3 after removing python3, and virt-manager is back to working normally. For some reason, it does not play nice when python3 is installed. I'll do some more testing before marking this thread as solved. Thank you willy for the quick reply as always. Likewise to rworkman.

Indeed, pygobject3 does not like having python3 installed. Well, virt-manager does not like that combination. So, I went ahead and built python3 after building pygobject3. So, I can mark this as solved. Thank you!
