Scary Ubuntu incident

Hello Ubuntu Technical Support
Ubuntu died on me today while it was doing nothing for me.
The sidebar with all my apps , active and inactive, was still shown but
no "Activities" icon at top left.
None of the apps could do anything and the "Show Apps" grid at bottom
left flashed icons on the screen that went blank.
I tried to shut down but the power light on my PC box kept flashing.
Pressing it reverted to the same display of the sidebar with apps.
Finally I disconnected the mains power and then restarted.

Software Updater

Hello Ubuntu user technical support

The last three or more Software Updater updates have ended with this
message:

Package operation failed
The installation or removal of a software package failed.

I have tried to read System log but find nothing that I can understand;
too complex for my limited knowledge.

I don't see any app failing, but something needs to be fixed because I
think there may be unnoticed damage.

Please tell me what other tracing methods or corrective commands I can
use.

Hope you all have a good festive time with family and friends.

Kind regards. Chas (retired user)

Synaptic package reload errors

Hello Ubuntu users
The errors shown below occurred when I tried to Reload Package
Information in Synaptic. I tried to check /etc/apt/sources.list

Target Packages.

18.04 has no support for my printer

Hello Ubuntu Support

18.04 looks good until I discover that I cannot print. Your advice will be
a huge relief.
Maybe I could restore files from 16.04 backup but have no idea which files
I would need?

I have added some lines from the HP diagnose utility that may be helpful?

Snap tutorial crashed my repositories

Hello 

I saw so much news from Ubuntu about snaps that I thought it was time I
learnt more.

So I found the tutorial on the website :

<a href="https://tutorials.ubuntu.com/tutorial/basic-snap-usage#1" title="https://tutorials.ubuntu.com/tutorial/basic-snap-usage#1">https://tutorials.ubuntu.com/tutorial/basic-snap-usage#1</a>

I am a retired Ubuntu end user so I tried just reading the steps first.
Then tried to install snapd. 41 packages were "no longer required" as
you will see from the clips of terminal messages below.
I don't know why apt could not connect to the network because I was
able to access other websites.

Help please: Network Service Discovery Disabled

Greetings All

I keep getting this warning. My new TP-LINK router still connects as Auto
Ethernet but maybe I should change some configuration if you can send me
terminal commands.
"Network Service Discovery Disabled" appears on my screen with the message
below that I could not copy.
So I scanned Syslog and found the details below. Upper case is my edit. I
have a text file with more of syslog if you want that.

Firefox sending huge mystery

Good day all

I noticed data transmission going on in the System Monitor that I did
not start.
It has sent out 127MB today.
After hunting for a cause I closed Firefox and the transmission stopped.

Can anyone explain what Firefox is doing please? I am alarmed that my
security is at risk.

Thanks for your advice. Chas IRONS

Scheduling jobs after midnight

Hello Ubuntu-users

I want to do software updates after midnight. I am sure a program
exists but cron does not seem to be it.

I assume the new Software Updater will work after midnight ?

Please name a suitable program and a help source for step-by-step
instructions.

Thanks for your expertise. ChasI

Re: Wanted: Pro to build dual boot Ubuntu

Hi All

After reading your various advices again, I hope my response makes sense
and any comments are most welcome.

Doug: I agree Win 7 will be better for me if I can find a source here
and will use it to shrink its partition to 20% of the hard drive.

Colin & Pep3ts: I have saved the link to Team Viewer in case Unity still
gives me trouble.

Wanted: Pro to build dual boot Ubuntu

Hi all

I have followed Joep Blom's saga with wine and am impressed by the
willing help Colin, Nils and others have offered.

I hope this forum will find a professional who provides a commercial
service in Randburg.

I am a retired end-user of Ubuntu 12.04 on a 9 year old desktop that I
need to replace. It dual boots Win XP.

The SARS online efiling won't work with Ubuntu since Adobe dropped
Flashplayer for Linux.

How many megabytes is 14.04.1 upgrade?

Hi all

I want to upgrade to Trusty Tahr but am wary of the download being
bigger than my data deal that is capped at 2 Gig each month.

So please tell me how many megabytes will be downloaded.

Thanks a stack. Chas.I
