I have an ethernet cable connected to the router and I set up the ubuntu server with the IP 192.168.1.123 using the installation of Ubuntu Server 20.04 Manual IPv4. I used Set static IP on Ubuntu Core and tsteiner answer. This finally worked for installing apt-get commands such as upgrade and update. I am not sure if I set it up right. I really just want to setup a server I can use but access from my desktop computer.
The commands ifconfig, route, and arp all tell to install net-tools which I can't because it can't contact the internet. Sorry
IP Address says enp0s7 inet 192.168.1.123/24 bed 192.168.1.255 scope global enp0s7 valid_lft forever preferred_lft forever inet6 fe80::7285:c2ff:fe5a:9ae5/64 scope link valid_lft forever preferred_lft forever
IP Route default via 192.168.1.254 dev enp0s7 proto static 192.168.1.0/24 dev enp0s7 proto kernel scope link src 192.168.1.123
Also I know I don't have a proxy setup for it and I really don't know how. I know about it being in the /etc/something.
The Subnet that is showing is 255.255.255.0 but then I need it in the CIDR form which it says doesn't exist for 255.255.255.0
