Upgrade to 18.04 fails

Question

Whn running do-release-upgrade

I get the following

Checking package manager
Reading package lists... Done    
Building dependency tree          
Reading state information... Done

Calculating the changes

Calculating the changes

Could not determine 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.

It seems grub is correct though

sudo dpkg -l | grep ^..r shows nothing.

Any suggestions for fixing ?

Hadnt tested it, Was on phone When I posted that. Back on a PC and this is the cause of the issue – exussum Jun 30 '18 at 19:16
@VolkerSiegel but in the original post the question was "Any suggestions for fixing ?" so that was my answer... – Artem Mygaiev Jul 01 '18 at 09:46
BTW, this is located in "Software & Updates" > "Developer Options". It was already disabled for me, still it didn't work. – iammilind Nov 09 '18 at 02:33

Judging by the version numbers, you seem to have unwisely added 18.04 (Bionic) repositories to a 17.10 (Artful) system.

DON'T mix packages from different releases of Ubuntu - doing so will break your system in precisely this way.

Delete the 18.04 sources in /etc/apt/sources.list. The release-upgrade tool will recreate the new sources at the appropriate time. Update the package database to reflect the changed sources using sudo apt update. Then try the release upgrade again.

If you added non-Ubuntu sources, you might need to uninstall those non-Ubuntu packages. Sometimes the files they provide are different (file conflict), or their version number is confusing (version conflict).
