Replying to the automated email and attaching a file doesn't work. The output is also text so why an image? Just copy the text and paste it as an update...

Forums are text based and the terminal is text based. Why use an image?

OK here's cut and paste. Why image, first, I'm an artist that's what I work with 2) I didn't know you could cut and paste in Terminal. Thanks,

Why don't you use copy and paste?
You again mistyped the command (there's a colon, not a dot).

It seems that libreoffice blocks the upgrade for whatever reason.
I suggest that you uninstall libreoffice, do the release-upgrade and install libreoffice again.

Thanks Manfred,
I am trying as you suggested. I appreciate the help.
Didn't appreciate the comments. This computer balks at odd moments. I tried cutting and pasting commands using keyboard shortcuts and it didn't work. I figured maybe that meant I can cut and paste from Terminal, but not to it. So I went back to manual. It's a learning curve.
Anyway, I removed all Libre Office and tried upgrade failed again. I'll try once more after restarting the computer and let you know.
Cheers, Jeff

If you want to copy or paste from the terminal window, you can either do a right mouse click and then select copy or paste from the pop-up window, or you can use the keyboard shortcuts ctrl-shift-c for copy, ctrl-shift-x for cut and ctrl-shift-v for paste (note that you also have to press the shift key).

What is now the output of
tail /var/log/dist-upgrade/term.log
tail /var/log/dist-upgrade/apt.log

Didn't I send you this already?

FYI- I normally use control c to copy and control v to paste. I use fastmail. When I control shift c it opens up some weird windows in fastmail. So just using r click and menu.
First command didn't appear to do anything.

OK, run:

sudo apt-get --purge autoremove
sudo apt-get clean

Then try the upgrade

Your last output shows that the release upgrader also has problems in upgrading mono packages.

I suggest that you also uninstall mono-runtime-common, mono-gac and mono-4.0-gac (and any packages dependent on these) and try again.

OK, As I said before, I'm not very versed in all the details of using Terminal. Can you explain how to do that or send the commands I'll need? Thanks

to uninstall the packages use the commands

sudo apt purge mono-runtime-common mono-gac mono-4.0-gac
sudo apt --purge autoremove

That worked perfectly. Hope you survived.
