In reply to faizan. @Faizan, If you have taken a backup using rsync or tar, you can use the following command to restore it:

rsync -av --progress /path/to/external/drive/username /home/
OR
tar -xvzf /path/to/external/drive/backup_home.tar.gz -C /

In reply to greek. I got this exact same problem too. I found a workaround for this. We need to use an app called Synaptic to remove all packages that are considered unofficial. Steps:

Install synaptic with "sudo apt-get install synaptic".
Open synaptic app and find the list of obsolete packages by clicking on the “Status” button and selecting “Installed (local or obsolete)”.
Select all of the obsolete packages and mark them for removal, then click on the Apply button. (Note: Your important apps may listed as obsolete packages, so make sure to back up the app data if possible. You may also need to keep the list by using a screenshot, so you can install them back later after upgrade).
Do the upgrade process again by pressing Alt+F2 type "update-manager -c -d" then click enter.

Hi, I’m facing an error in ubuntu 18.04.

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

This was likely caused by:
* Unofficial software packages not provided by Ubuntu
Please use the tool ‘ppa-purge’ from the ppa-purge
package to remove the software from a Launchpad PPA and
try the upgrade again.

If none of this applies, then please report this bug using the
command ‘ubuntu-bug ubuntu-release-upgrader-core’ in a terminal. If
you want to investigate this yourself the log files in
‘/var/log/dist-upgrade’ will contain details about the upgrade.
Specifically, look at ‘main.log’ and ‘apt.log’.
