I have tried to upgrade 18.04 to 19.10 using command lines but there is one issue it's showing me is that:

Please install all available updates for your release before upgrading.

I have also tried for updates and it's showing it's up to date, now what I can do for upgrade my 18.04 Ubuntu to 19.10?

If you are not afraid of OS reinstalling and if you use your 18.04 at home, but not on prod, than you could experiment with not supported methods. But prepare your Ubuntu installation usb flash drive before. You could encounter drivers related issues, dependency related issues which will lead you to OS reinstallation.

To update to 19.10, you could try the next:

  • remove old, unsupported by 19.10 packages that could be the cause of broken dependencies if you know what are these packages
  • move everything from /etc/apt/sources.list.d/ to some safe place and remove all packages installed from these sources with following sudo apt autoremove
  • leave at least one desktop manager, one desktop environment, get rid of any additional or big applications that have a lot of dependencies by purging them

  • sudo apt autoremove && sudo apt update && sudo apt upgrade

  • backup your current /etc/apt/sources.list and create the new one:

    deb http://ru.archive.ubuntu.com/ubuntu/ eoan main restricted
deb http://ru.archive.ubuntu.com/ubuntu/ eoan-updates main restricted
deb http://ru.archive.ubuntu.com/ubuntu/ eoan universe
deb http://ru.archive.ubuntu.com/ubuntu/ eoan-updates universe
deb http://ru.archive.ubuntu.com/ubuntu/ eoan multiverse
deb http://ru.archive.ubuntu.com/ubuntu/ eoan-updates multiverse
deb http://security.ubuntu.com/ubuntu eoan-security main restricted
deb http://security.ubuntu.com/ubuntu eoan-security universe
deb http://security.ubuntu.com/ubuntu eoan-security multiverse

  • try do-release-upgrade

I've successfully upgraded 18.10 in the past, but on the VM and using fresh installed 18.10.

(Recommended) Don't update to 19.10 from 18.04 Since, 18.04 is LTS and 19.10 is not. I have already done. I have seen hell!. It freezes within 3 hours during normal usage. Nothing works, only option was to hard shut down using power button. Wait LTS for 19.10 will release in april.
