Installing ubuntu server 20.04 via live cd. I am at the network setup

Manual setup static ip (I am using public IP Address) and i get the error shown after entering the IP


Address xxx.xxx.219.146

xxx.xxx.219.146 is not contained in

Gateway xxx.xxx.219.132

This of course is incorrect as it is contained in the subnet The IP range is from xxx.xxx.219.128 through to xxx.xxx.219.159

Useable IP's are from xxx.xxx.219.132 - xxx.xxx.219.158

You cannot proceed with the setup as it does not allow you to with the above error. Unless you select DHCP which i do not use. As it also does not get assigned an IP from DHCP the interface is auto disabled.

Any ideas on where i am incorrect or work around would be greatly appreciated :) Thanks in advance

  • If i enter just the subnet it gives the error Should be in CIDR form xx.xx.xx.xx/yy – Patdundee Sep 4 '20 at 20:37
  • is not a valid subnet. It can be, however, a valid subnet mask. The two are not interchangeable. – user535733 Sep 4 '20 at 20:44
  • Thats what happens when you get brain strain I should have noticed it before i posted :) – Patdundee Sep 5 '20 at 8:57

Just figured it out it is asking for a subnet not a subnet mask

instead of the subnet

i needed to enter the range xxx.xxx.219.128/27 :)
