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)

Objet: [PVE-User] Problem with ifupdown2


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 
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or after reboot, the network interfaces are no longer active 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. 

Best Regards.
