I'm in the process of upgrading my Ubuntu system from 14.04LTS to 16.04LTS. (This is a server system, and is accessible through the command line only)

Anyway, I attempted to do the upgrade:

sudo do-release-upgrade 

...

and it failed:

Please report this as a bug and include the files
/var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in
your report. The upgrade has aborted.
Your original sources.list was saved in
/etc/apt/sources.list.distUpgrade.

SystemError: E:Sub-process /usr/bin/dpkg returned an error code (1)

I rebooted my system, and I still have access to it. However, my system is only partially upgraded. I'm trying to figure out how to "complete" the upgrade:

It thinks I'm on 16.04:

lsb_release -a

LSB Version:    core-2.0-ia32:core-2.0-noarch:core-3.0-ia32:core-3.0 noarch:core-3.1-ia32:core-3.1-noarchh

Distributor ID: Ubuntu

Description:    Ubuntu 16.04.5 LTS

Release:        16.04

Codename:       xenial

Trying to manually do the update fails:

sudo apt-get update && sudo apt-get upgrade

The following packages have been kept back:

A dist-upgrade gives me the same result:

When I manually attempt to upgrade "parted", I get the following errors:

Some packages could not be installed. This may mean that you have

requested an impossible situation or if you are using the unstable

distribution that some required packages have not yet been created

or been moved out of Incoming.

The following information may help to resolve the situation:



The following packages have unmet dependencies:

 libparted1.6-0 : Conflicts: libparted2 but 3.2-15ubuntu0.1 is to be installed

                  Recommends: libreiserfs0.3-0 but it is not installable

 libparted1.6-12 : Conflicts: libparted2 but 3.2-15ubuntu0.1 is to be installed

 libparted1.6-13 : Conflicts: libparted2 but 3.2-15ubuntu0.1 is to be installed

E: Broken packages

I (stupidly) thought that I should upgrade from 16.04 to 18.04, but when I run the command now, the system recognizes that the packages aren't all upgraded:

sudo do-release-upgrade

Checking for a new Ubuntu release

Please install all available updates for your release before upgrading.

So, how do I get the install to continue to complete? I have tried various commands without any success:

sudo dpkg --configure -a

sudo apt-get clean 

sudo apt-get update --fix-missing

sudo apt-get install --fix-broken

I'm not totally sure exactly what I did, but it seems that this command got me rolling again:

sudo apt-get --reinstall dselect-upgrade
