This morning's update seems to have broken QEMU/KVM

[oshunluvr]

This morning The Virtual Machine Manager" reported "no connection..." so I rolled back to yesterday and it now works fine.

I captured the list of installed packages and decided these were related to libvirt:

libspice-server1
libvirglrenderer1
libvirt-clients
libvirt-daemon-config-network
libvirt-daemon-config-nwfilter
libvirt-daemon-driver-qemu
libvirt-daemon-system-systemd
libvirt-daemon-system
libvirt-daemon
libvirt-l10n
libvirt0
ovmf
python3-libvirt
qemu-block-extra
qemu-system-common
qemu-system-data
qemu-system-gui
qemu-system-x86
qemu-utils
seabios
spice-vdagent
virt-manager
virtinst

so I updated all but these and rebooting in a few minutes to test.

This seems to have temporarily solved the issue.

I have turned off my auto-update for now. I'll try it again in a week or so...

I thought this was from my using Canonical's Server Team Backports PPA, which had a few updates yesterday. Today? My yesterday, anyway.
A few packages were removed, but I decided to go with it, because I can roll back, or use my laptop for virt-manager for now.

Updated yesterday and this is still happening. Seeks like this might be the issue:

Based on the above output, I installed "libvirt-clients" and it's depends:

The following packages were automatically installed and are no longer required:
libvirt-daemon-config-network libvirt-daemon-config-nwfilter libvirt-daemon-system-systemd mdevctl
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:

libvirt-daemon-driver-storage-zfs libvirt-daemon-driver-lxc libvirt-daemon-driver-vbox libvirt-daemon-driver-xen libvirt-daemon-system numad passt

5 upgraded, 0 newly installed, 1 to remove and 16 not upgraded.
Need to get 6,984 kB of archives.
After this operation, 850 kB of additional disk space will be used.

and this IMMEDIATELY broke QEMU/KVM. I assume it's the removal of libvirt-daemon-system that causes the problem.

For the last several days I've NOT upgraded these 22 packages:

libvirglrenderer1
libvirt-clients
libvirt-daemon-config-network
libvirt-daemon-config-nwfilter
libvirt-daemon-driver-qemu
libvirt-daemon-system-systemd
libvirt-daemon-system
libvirt-daemon
libvirt-l10n
libvirt0
ovmf
python3-libvirt
qemu-block-extra
qemu-system-common
qemu-system-data
qemu-system-gui
qemu-system-x86
qemu-utils
seabios
spice-vdagent
virt-manager
virtinst​

Assuming you are using the same PPA source, I think that there is a packaging misconfiguration on libvirt-daemon-system, I think. (I am AFK ATM)

I think this package depends on a version of something from a later release than 22.04 privides, and not in the PPA. I'll report which thing later.

[oshunluvr]

This is still a problem. In order to do system updates, I have taken to:

1. Running "apt list --upgradable" after updating and using awk to deliver only the package names to a text file.
2. Manually editing the file to delete the 22 packages for libvrt in the list,
3. Feeding the list to "apt install"

This is the only way I can update at the moment. I suppose I could go though and lock all 22 packages, but then it would be harder to test upgrading them - being ever optimistic that someone will fix this.

[oshunluvr]

I have narrowed it down to these packages:

libvirt-clients
libvirt-daemon-config-network
libvirt-daemon-config-nwfilter
libvirt-daemon-driver-qemu
libvirt-daemon-system-systemd
libvirt-daemon-system
libvirt-daemon
libvirt-l10n
libvirt0
python3-libvirt

[claydoh]

Are these stock Ubuntu packages, or from PPA? I simply disabled that in Discover.

And yes I forgot to check what the possible packaging issue was.

[oshunluvr]

I just booted to a fresh KDEneon install and when I updated it, the QEMU version is a version older than the one I'm getting here on my old install. Odd.

Also, libvirt-daemon-system from that PPA depends on polkitd version newer than what is in Jammy, which is a PPA build or packaging issue

The following packages have unmet dependencies:
libvirt-daemon-system : Depends: polkitd (>= 121+compat0.1-2)

I have emailed the Server Team about this.
