18.04 upgrade not working

[Gaurav Agarwal]

I am currently into version ubuntu 16.04, somehow I got to know about the new release 18.04 and I can directly upgrade it through software updater tool. I did that, the tool even showed that you have 18.04 update available. I started the update, everything went fine, I did what it asked me to do, it took time and everything went fine, then after restart I found no changes to my computer, I then checked with about this computer information in PC, it showed as 16.04 version only, that means no upgrade, but when I tried to again check update with the software updater tool, It showed that my software is up to date.

You have some broken packages: https://launchpadlibrarian.net/369595119/VarLogDistupgradeAptlog.txt

and you have installed non ubuntu genuine packages (seen some from debian for example); so the first step is to made your install a pure ubuntu one, and downgrade version when required.

Otherwise optin for a fresh install.

Where are you seeing information that indicates you are running "Ubuntu 16.04"? Could you include a screenshot of that information?

The data gathered by apport indicates that you are running Ubuntu 18.04.

Using "cat /etc/os-release" in a terminal would be another way to check. That information panel seems to be wrong.
