Still issues upgrading: libvirt-daemon-system : Depends: polkitd (>= 121+compat0.1-2) but it is not installable

Hi people,

I'm trying update our gns3 VM from 2.2.43 to 2.2.48.

However during install (and also when running gns3restore) I get

[...]

This is related to GNS3/gns3-server#2398 and #2402, how the solution doesnt work here.

According to this issue on Launchpad Its supposed to be a ubuntu repo problem?

I'm not sure what to do. We didnt really change anything about the VM.
Cheers and thanks

I'm trying update our gns3 VM from 2.2.43 to 2.2.48.

I have downloaded the GNS3 VM for v2.2.43 and upgraded to version 2.2.48. I didn't get any error.

Do you remember if the GNS3 VM you use had already been upgraded from an earlier version?

Also, what is the output of the sudo apt-cache policy libvirt-daemon-system command? Thanks 👍

Hey, thanks for your reply.

The VM has definitely been update before at lest once if not twice. However, I'm not sure with which version we started with.
Base-Image ist still ubuntu 20.04 if that relevant?

I think I understand what happened.

Looks like the Qemu version was upgraded (which is done by using the PPA ppa:canonical-server/server-backports repository). The same PPA is used when upgrading the libvirt-daemon-system package which result in the error you have seen.

Please can you try these commands:

sudo add-apt-repository -y --remove ppa:canonical-server/server-backports
sudo apt autoremove
sudo apt purge lvm2 

and then upgrade again.

Thank you so much, that has done it!

The libvirt package has been updated on the Server Team Backports PPA . This solves the issue without having to do the above workaround.
