I try to create new vm or see connection details with virt-manager but nothing append, no popup, no error message, nothing.

see here:

i click but nothing append i use arch with kde libvirtd is enable and my user is on group kvm and libvirt

virsh works fine

when i run virt-manager --debug and clicking i have this error:

[sam., 22 juin 2019 12:26:56 virt-manager 9274] DEBUG (cli:197) Uncaught exception:

ValueError: Namespace GtkSource not available

after some research i found that https://bugs.archlinux.org/task/62960 and installing gtksourceview4 package seems to solve the problem


That looks like a bug. Try running 'virt-manager --debug' from a terminal, and see if you get a backtrace when clicking the 'New VM' button

  • thanks, with the --debug i found the bug and find how to solve it – Equitable Jun 22 '19 at 11:10

After upgrading from Ubuntu 19.04 to 19.10 (devel) i also had to install gir1.2-gtksource-4, beside the packages libgtksourceview-4-0 and libgtksourceview-4-common.
