Ping works, wget, curl and apt do not... firewall disabled to make sure not the problem

So, as the message says, there is no firewall running at all at present but curl/wget do not work while ping does (also, I am SSHd into the machine and apache2 works so it can receive requests on port 80). This is a mystery for the ages! Here are some hopefully informative tidbits...

I am certain that it is not a firewall issue (firewall totally disabled)

My /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
auto lo inet loopback
# The primary network interface
#auto eno2
#iface eno2 inet static
auto eno1
iface eno1 inet manual
bond-master bond0
auto eno2
iface eno2 inet manual
bond-master bond0
bond-primary eno2
auto bond0
iface bond0 inet static
bond-mode active-backup
bond-miimon 100
bond-slaves none

restarting networking fails

systemctl restart networking.service
Job for networking.service failed because the control process exited with error code. See "systemctl status networking.service" and "journalctl -xe" for details.

here are the errors I get

Updates

Thanks @JohnRonald, I updated the iface line and that succeeded in restarting networking but it did not fix the curl/wget problem.

Here is the curl error @raj
