There are no traces of "a small update app 1200 Bytes". Can you remember some additional details?

What I see is the installation of linux-image-4.4.0-77-generic and linux-signed-image-4.4.0-77-generic as well as the deinstallation of a few other packages.
One of the packages that were removed is libldap-2.4-2, and this of course can be the cause that networking does not work any more (if your network setup depends on ldap functionality, and if your system does not have any other ldap client installed).

What was the reason (and the command) for purging the packages as listed in your log?

This is what I remember:

Early yesterday morning I got a message to run an update and strangely enough, it appeared to be a small one, it was done in a few minutes. Then it requested a restart, but I had a doctor's appointment I just shut down and came back later in the day . I started the computer and I found the wireless keyboard did not work. So I installed new batteries and it still did not work. The icon indicating network was blank and nothing I did would connect. A wired keyboard works, and another wireless mouse also works.

I have lost no data on the two 1TB disks, and the system is on a 120GB SSD

Normally an kernel update takes about 5 to 10 minutes, and shows a long list of items to be downloaded. It appears that the update started on its own without my consent.

I may have run Ubuntutweak which is still on my system, it refused to remove kernels, but did delete obsolete packages......?

If you boot an older kernel is it OK?

How do I get to an older kernel, that was a question I was going to ask as I also have a booting problem on a laptop.

BTW the use of ubuntutweak was long after the failure to connect to the Internet

Quite early during the boot process you have to press the shift button to get the grub menu.
And there you have several options, among others to select an older kernel for booting.

What output do you get for the command
ifconfig -a

ea@Discovery:~$ sudo ifconfig -a

And what is the output of

sudo lshw -C network

And what is the output of

dpkg -l | grep ' linux-i'

Maybe you are missing the package linux-image-extra-4.4.0-77-generic (or maybe the first and crucial part of the installation log is missing in your comment above).

USB sticks are really wonderful:

If I edit /ets/grub.d to change quiet_boot and quick_boot to 0 from one will I get the chance to boot another kernel?

Hold SHIFT at boot and select an older kernel. Does it work OK?

Hold SHIFT used both right and left separately did nothing but boot the current Kernel.

Again how do I edit GRUB to show all kernels?

You hold it as soon as the BIOS screen goes

Issue the command

sudo gedit /etc/default/grub

and modify the lines 6~9 into

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10

Save the file and close the editor, and reboot.
You should see the grub menu.

Oops, one step missing:

edit the file /etc/default/grub as described above
Issue the command "sudo update-grub" and then reboot.

I made the changes as suggested.

Reboot, same problem.

I read the info file, and found that pressing ESC during the boot process gave a menu where I had the choice of booting th default or choose. I choose the next lowest kernel (75) and I have my system back

Now to get rid of kernel '77' and al will be well
I will be away for a while , not finished yet.

I believe the cause of the above problem was that I was not aware a kernel update was running when I shut the system down.
I have since found that holding 'shift' down during the boot phase does not work, but holding 'ESC' does work and presents a menu of all currently installed kernels.

Now I have to get rid of the faulty kernel update.

If you use apt pinning you can lock the kernel and it won't update

I suggest verifying the status of your package management system with the command

sudo dpkg --audit

I do not know "apt pinning"
Dpkg -- audit ran and showed nothing, thus no errors there.

I also found 'Grub Customizer, it removed kernel 77 from the grub file, but booting still presented '77' not '75'

Grub Customizer worked, by removing kernel '77' and setting the first usage to '75' which is the first in the list of kernels.

I shut down the system, and started again, did this twice and I now have a working system. However I need to be aware of what I did in case an upgrade happens, as I set the usage specifically to '75'. An update might not change that.

What is now the output of

dpkg -l | grep ' linux-i'
apt-get --simulate dist-upgrade

from reading "apt-get" help itappears that a command like "apt-get purge linux-image-4.4.0-77-generic 4.4.0-77.98" may get rid of the offending package??

Thanks Manfred Hampl, that solved my question.
