No network connnection on ubuntu server

[akio123008]

I've just set up an ubuntu server system and everything works, except for the network connection. At first, the network connection wouldn't work at all,

which I fixed by doing:

 

sudo ifconfig enp2s0 192.168.1.90 netmask 255.255.255.0

 

the main network interface turns out to be called enp2s0, which I found out using ifconfig -a

 

the command above made the connection work, but there's a problem: every time the system reboots, it returns to the old state and I have to run the command again to get my network interface to work. Does anybody know how to fix this?

You need to manually configure it in /etc/network/interfaces (I forget of this changed in 18.x)

The config, at least from what I saw last, varies greatly from 16.04 to 18.04 so depending on which version will depend on how exactly you go about doing that.

Yes I saw some stuff online about that, but when I access the config file it tells me the network configuration is handled by Netplan (basically telling me "this file is useless") which is used in newer versions of ubuntu instead of ifupdown.

You need to use netplan in ubuntu 18.x+

 

It's not hard. Edit the only file in /etc/netplan/xxxxxx.yaml accordingly (look up a guide), then type sudo netplan generate and sudo netplan apply and you should be fine.

Netplan was a bit of a pain to deal with but the machine is now fully operational. Thanks for the help!
