Hello world I have a Promox on a laptop with KDE for lab purposes and it work like a charm. (install Proxmox and "apt install plasma-desktop") Now i want to step up a little this lab by installing GNS3. "apt-get install gns3-gui" -> The following packages have unmet dependencies: gns3-gui : Depends: gns3-server but it is not going to be installed After a few research, i found that libspice-server1 is needed by GNS3 but it enter in conflict with "pve-libspice-server1". As i understand it, pve-libspice-server1 just add some stuff to the original libspice-server1 from spice-common for Proxmox needs. So my guess is if i manage to tell the dependencies system on my Proxmox that pve-libspice-server1 is libspice-server1 it would work. The other workaround would be to compile GNS3 by myself and link the pve-qemu-kvm to GNS3 in place of qemu-system-x86 originaly needed. What do you recommend ? Any tips or idea ? Regards.
