Changing VM IP /etc/network/interfaces - blank

[voarsh]

Hi.
I'm not sure how I can modify a VM's IP address, the /etc/network/interfaces is blank, so I don't see a way to change it.

Any pointers?
Thanks.

Hi,
Which linux distribution is the VM running? /etc/network/interfaces is mostly only for Debian/Ubuntu network configuration.

Yes, I was using Ubuntu.
So I am not sure why it was like that.

Oh, the reason is that Ubuntu have been shipping with Netplan [1] as their network configuration tool of choice, rather than ifupdown [2], since version 17.10, so it uses an entirely different configuration system. Apologies for the mixup; I don't really follow/use Ubuntu myself. Configuration settings can also be found at [1].

i tried to update it to static by watching a netplan ubuntu configuration.
but when i run a test it just tells me that netplan configuration should not be accessible by others

prior detail:
- i didn't had a network config file other than 50-
- i created my own
