Can not install "qemu-system-x86"

I am on excalibur now. "qemu-system-x86" somehow depends on "python3-libvirt" which is 9.7.0-1 as of today and then it depends on libvirt0 (>= 9.7.0). But today in the  excalibur and ceres repos we only got  libvirt0 9.6.0-1devuan1.

Re: Can not install "qemu-system-x86"

got python3-libvirt_9.6.0-1_amd64.deb from the debian snapshots and it did the trick though it is not right. I think the repos should be revised.

Yeah. It's something to look at when excalibur is going stable.

Re: Can not install "qemu-system-x86"

The same problem still persists in excalibur today.
Versions:

• python3-libvirt (= 10.5.0-1+b1)

• virt-manager (= 1:4.1.0-4)

# apt install virt-manager

The following information may help to resolve the situation:

Unsatisfied dependencies:
 python3-libvirt : Depends: libvirt0 (>= 10.2.0) but 10.0.0-1devuan1 is to be installed
Error: Unable to correct problems, you have held broken packages.

I tried to modify the dependency to libvirt0 in DEBIAN/control of the python3-libvirt package to 10.0.0-1devuan1 which breaks virt-manager.
I also tried to install libvirt0_10.5.0-1_amd64.deb from debian testing which makes virt-manager functional but breaks at least:

• libvirt-clients (= 10.0.0-1devuan1)

• libvirt-daemon (= 10.0.0-1devuan1)

• libvirt-daemon-driver-qemu (= 10.0.0-1devuan1)

• libvirt-daemon-config-network (= 10.0.0-1devuan1)

• libvirt-daemon-config-nwfilter (= 10.0.0-1devuan1)

• libvirt-daemon-system-sysv (= 10.0.0-1devuan1)

I then tried to change the version of libvirt0_10.5.0-1_amd64.deb to 10.0.0-1devuan1 and installing it together with the modified python3-libvirt package, but this breaks too because libvirtd needs the older version of libvirt0:

/usr/sbin/libvirtd:
 /lib/x86_64-linux-gnu/libvirt.so.0:
  version `LIBVIRT_PRIVATE_10.0.0' not found (required by /usr/sbin/libvirtd)

UPDATE:

Based on #2 i found python3-libvirt_10.0.0-1build1_amd64.deb from the Ubuntu archives. Installing this package seems to make virt-manager and qemu-system-x86 work without problems.
