I take it this is in /etc/network/interface or in a file below
/etc/network/interfaces.d

I suspect a lack of firmware. What is the interface hardware? Run lspci
to determine which device is your network interface, something like:
root@iorich:~# lspci
...
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN
[Kedron] Network Connection (rev 61)
...
root@iorich:~#
Use the identifier at the left to get more information on the hardware:
root@iorich:~# lspci -v -s 03:00
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN
[Kedron] Network Connection (rev 61)
Subsystem: Intel Corporation Lenovo ThinkPad T51
Physical Slot: 3
Flags: bus master, fast devsel, latency 0, IRQ 32
Memory at df3fe000 (64-bit, non-prefetchable) [size=8K]
Capabilities: [c8] Power Management version 3
Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [e0] Express Endpoint, MSI 00

Capabilities: [140] Device Serial Number 00-1d-e0-ff-ff-99-75-25
Kernel driver in use: iwl4965
Kernel modules: iwl4965
root@iorich:~#
Notice the kernel driver in use, in this case iwl4965.
Now see if it has been loaded.
root@iorich:~# lsmod | grep -i iwl4965
iwl4965 110592 0
iwlegacy 90112 1 iwl4965
mac80211 983040 2 iwl4965,iwlegacy
cfg80211 970752 3 iwl4965,iwlegacy,mac80211
root@iorich:~#
Did the firmware get loaded? Search /var/log/syslog on the name of the
driver (iwl4965 in this case). Shortly after boot, you should see a
message indicating success or failure of loading the firmware.

Does anybody read signatures any more?
