Software updater displays blank page

Ubuntu-Mate 16.04
Kernel Linux 4.4.0-131-generic x86_64
MATE 1.12.1

The software updater is not displaying the update details any more, just the total space required for the update.
I believe that this change ha only happened since the most recent Kernel update, ie 131.
I have switched server from Australia to Main and back again without any change

Hi @zylmurbafi. I’m leery of your kernel version being a clue. The most recent kernel should be 4.4.0-134 and my Synaptic history says I got that 8/24 . I got 4.4.0-131 on 7/24 but I maintain only 2 kernels (-134 and -133 now) so it’s gone.

I wonder if some update got snagged. This can be fixed with:

sudo dpkg --configure -a

If all is normal, nothing will happen. Otherwise there may be input needed.

Or is there any chance your /boot filled up? A quick check:

df -h /boot

Also, coincidentally, the Updater recently started the 18.04 upgrade notification but I can’t imagine this could be involved.

Thanks Bill_MI
The sudo dpkg --configure -a returns nothing and my disk shows 19% as I use another disk for data only.
I’m stumped, because this has never happened to me before for over 10 years using ubuntu.
I agree it prob has nothing to do with kernel 131, only its the last update I have performed not knowing what the total space required of 241.5Mb entails without details.

The only other thing I have recently installed is Encfs but that seems to work OK.
All other activities appear to working without a hitch, too.

Do you think I should trust the system and update anyway not knowing what it will be and see what happens??
I suppose I can always check the update history later to see…

I don’t know why my updates haven’t got me to 134 although of course I haven’t agreed to update for a month because of the uncertainty.

Anyway, if you have any other suggestions they would be very welcome.

Could it be this bug? https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1783023

The bug @anon64428677 mentions is on 18.04 but could apply.

I’ve been a Synaptic user for over a decade but there’s always the commandline to maybe get a clue.

sudo apt update
sudo apt upgrade

It won’t do anything unless you ok it. Here’s exactly what I’m seeing today and I said NO so Synaptic will do it later.
