Ubuntu server static IP not working

Go to solution Solved by jj9987,

Wrong subnet. You don't use both the mask address and prefix together.

 

If you need mask address, you only use the mask address, that's the 255.255.255.0.

If you need subnet mask prefix, you use it only as network address (which here would be 192.168.1.1/24).

Hello i am tryng to set a static IP on a ubuntu server 18.04

Just now, Kylian said:

Umm, no. Windows also uses dot-decimal notation for subnet masks in network settings, not the network address.

AFAIK in Linux you don't typically use /24 either, except for some specific services such as NFS exports.
