Cannot upgrade to ubuntu 18.04 from 16.04

Asked by Raj Khandor

I am running Ubuntu 16.04 .
Everytime I turn on the system it says system problem detected .
So I tried to upgrade it, but even that fails.

Terminal Output :

raj@raj-lenovo-ideapad-320-15isk:~$ sudo do-release-upgrade

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.

Usually the files in /var/log/dist-upgrade/ provide details.

What is the output of
cat /var/log/dist-upgrade/main.log
tail -n 50 /var/log/dist-upgrade/apt.log

I see two possible paths for you:

1. You should add the "xenial-updates" repositories and perform a full package upgrade on xenial.
It seems that you do not have the newest versions of the packages for xenial. Such package upgrade might be the solution for the "system problem detected" message after each boot, or may solve the dependency problem for the release upgrade.

2. Based on your output I suggest that you uninstall python-scipy and libgfortran4 (and the packages depending on these two), and then re-try the release upgrade.

Thanks Manfred Hampl, that solved my question.
