if you have purge ifdown, it'll disabled networking service. (ifupdown2 use the same service name)
Simply reenable them with "systemctl enable networking". about ifenslave, it's removed, because it's not needed by ifupdown2. (ifupdown2 don't need any /etc/network/if-*.d/ scripts) ----- Mail original ----- De: "Jean-Daniel TISSOT" <jean-daniel.tis...@univ-fcomte.fr> À: "Proxmox VE user list" <pve-user@lists.proxmox.com> Envoyé: Mercredi 9 Septembre 2020 13:05:36 Objet: [PVE-User] Problem with ifupdown2 Hi, I installed the ifupdown2 package from the Proxmox repositories, this uninstalled the ifenslave and ifupdown packages. I usually uninstall configuration residue from packages deleted by the command: apt -y purge $(dpkg -l | awk ' /^rc/ { print $2 } ') or after reboot, the network interfaces are no longer active The command: dpkg -L ifenslave lists the following files: /etc/network/if-post-down. d /etc/network/if-post-down. d/ifenslave /etc/network/if-pre-up. d /etc/network/if-pre-up. d/ifenslave /etc/network/if-up. d /etc/network/if-up. d/ifenslave The command: dpkg -L ifupdown lists the following files: /etc/init. d/networking How is it that the ifupdown2 package does not contain these files since its installation removes the ifenslave and ifupdown packages? Thanks to the developers to include the files necessary for the proper functioning of ifupdown2.
