I have 16.04 on a dell 390 . 16.04 was installed 2 or 3 yrs ago and a number of updates were done over time. At some point i believe updates stopped. I have recently tried to fully update and i get a message:

'The package system is broken. If you are using third party depositories then 
disable them ...run 'apt-get install-f Transaction failed ...unmet 
dependencies;   evince:depends: libevdocument3-4(=3.18.2-ubuntu4.4 but 
3.18.2-1ubuntu4.4is installed. Depends libevview 3.3 (=3.18.2-1ubuntu4.4)but 
3.18.2-1ubuntu4.3is installed.

I have no idea what this means or what to do. I would like to:

  1. To complete all updates and thus fix the problem above

  2. Separately, to upgrade to 19.04 if possible

Can anyone please give a clear instruction of what I must do. Please do not assume any level of competence on computers......I am a ski instructor and 'masterful lover' but sadly, not a pooter expert. I am most grateful for help and advice. THANKS!

NOTE: do NOT go to 19.04. If you go you need to first go to 18.04 and then to 20.04. Maybe you can go straight there?

Check and Repair

sudo dpkg --configure -a

Looks for and install missing dependencies 

sudo apt-get -f install

Sometime the hard disk gets too full Running the update from the command line you will see somewhere "insufficient space"

sudo apt-get update

sudo apt-get upgrade

(Running updates from muon you consistently get "Could not download packages" Your root partition is likely too full.) This has often happened during a copy when the target is incorrectly specified and the drive makes it up and fills it up. Look for the big files/folders that are not needed and delete them.

Sometimes the headers/sources get messed up. 

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

No updates appear. Change your main repo and they will rebuild and may appear. The package lists may get broken. 

sudo apt-get clean
sudo mv /var/lib/apt/lists /tmp
sudo mkdir -p /var/lib/apt/lists/partial
sudo apt-get clean
sudo apt-get update

Hi Walt Thanks for the advice re going to 20.04 - i will do that Is there a place I can get tuition on how to do that sudo dpkg --configure -a stuff? It really needs to be basic. I have tried to find youtube training but i can only find two types of ubuntu training. 1. How to turn ubuntu on - i can manage that now 2. All that sudo stuff and there NOTHING in between

Also - Im pretty sure its not the disk as I use this computer only for mail and there is nothing else on it. Many thanks for your patience with me
