Is your system 32bit as I doubt it has a 32bit version – George Udosen Aug 17 '18 at 19:07

@GeorgeUdosen I've heard many people are getting update for 18.04 from in 16.04 32bit. But I doubt on the performance. – Kulfy Aug 17 '18 at 19:20

If your system is 64 bit then go for it! – George Udosen Aug 17 '18 at 20:35

First of all, if the CPU is 32-bit, you can't install a 64-bit OS on it.
Judging by the answers on Is it possible to "upgrade" from a 32bit to a 64bit installation? and How can I switch a 32-bit installation to a 64-bit one?, it is very difficult to switch from 32- to 64-bit, so I can't imagine the upgrade would do it for you.

1That's correct the release upgrader will not switch to 64 bit for you. – Brian Murray Aug 17 '18 at 20:29

According to answer on this question you can upgrade 16.04 LTS to 18.04 LTS with 32-bit support:
Downgrade from 17.10 to 16.04LTS
There is a bit of confusion in this area.

If you have 32-bit architecture and want Ubuntu 18.04 server then you can download 16.04 server and then look at upgrading online to ubuntu 18.04.
