System Update froze - UbuntuMATE 16-04


I have tried to do a system update on this computer, which is (kind
of) running UbuntuMATE 16.04 .

The Software Updater shows

"Installing updates..."

and, under that, is
"Running post-installation trigger initramfs-tools"

(it is unfortunate that the window does not allow copying and pasting
of text in the window)

and it has been sitting there, with no progress for over half an hour
(it is on an i3CPU with 16GB of RAM, not an 8086 with 640kB of RAM).

The last two lines in the Details window (once again, it does not
allow copying and pasting), are

Is it possible to download packages from 16-04 repository to install on 18-04


It has occurred to me, as the Ubuntu Software Centre, Me TV, NetSurf,
and various other packages in 16.04 are not available in 18.04, is it
possible to download packages from the 16.04 repository, and, install
them in 18.04?

If so, how do we access the 16.04 repositotory and download the 16.04
packages, from 18.04?

Thank you in anticipation.

Me-TV and ubuntu 18-04


I have a UbuntuMATE 18.04 installation.

The Software Centre of previous versions, and, apparently, many other
packages, have been disappeared, in the change to 18.04 - they were in
previous versions of Ubuntu, but are not available in the (clean)
installation of Ubuntu 18.04 .

The Me TV application was the only TV application that I could get
working on 16.04.

The Me TV website makes it prohibitively difficult to contact any of
the Me TV people.

Are any of the MeTV developers on this list?

Newly installed UbuntuMATE 18-04 does not boot

Is a simple method of blocking a particular domain name or IP address set available


I am running UbuntuMATE 16.04.

Continuous Internet traffic is shown to be occurring.

Etherape shows it to involve a single domain name ( and its
IP address set (

I have tried to add a rule to deny it, using the Ubuntu firewall
software available through the Control Centre, but it requires, and,
limits each rule to, a single port number (which I do not know how to
find, for the traffic).

Is a simple method of blocking a particular domain name or IP address
set available, so that I can deny access to this domain name and/or
its IP address set?

mythtv package developers for Ubuntu packages


From posts on the mythtv mailing list, an inconsistency between the
general mythtv software and the mythtv packages for Ubuntu, appears to
have been advised, about which, I am advised, I should ruise a bug
notification with the package developers.

However, in the Ubuntu Software Centre information displayed about
mythtv, the "Developers website" link points to

So, I am wondering whether the developers of the mythtv packages for
Ubuntu, happen to be subscribed to, and, involved in, this list?

Wayland and Soiftware Updater


In preparing one computer for updating, then running the Software
Updater, 182MB of packages are to be downloaded.

In looking through the packages descriptions (which it lists, rather
than the package names), I found
""Implementation of the Wayland EGL platform - runtime"

From memory, Wayland is a nasty that wrecks p[eople's systems.

As it is shown there, and I had "updated" this system, in the last day
or so, I did a search in Synaptic (very useful software, is Synaptic)
for Wayland, and, found this system has that (the runtime) package for
Wayland, and, varuipous other Wayland pac

UEFI and Ubuntu Linux


I am currently running UbuntuMATE 16.04 LTS on various computers; UEFI
and otherwise.

In performing a system update on this one (a computer that has UEFI,
which is bypassed to run Linux), yesterday, I observed that the
packages to be installed/updated (I am not sure which), included a
number of packages relating to UEFI.

In checking using Synaptic, I found that 12 packages relating to UEFI,
are available, with a few of them, installed.

When I first installed Linux on this computer (it took me about two
years to get Linux properly running on this computer, due to three

Software updater snuck in a package that is unwanted

How do I remove a package that was snuck in?

The Software updater apparently installed a package that was listed as
"Automatically install upgrades" or something like that, because I did
not know how to permanently block it.

Synaptic shows it (I think) as unattended upgrades", with the
description "automatic installation of security upgrades".

Apparently, this trojan horse has the effect that, to remove it, so as
to revert to manually performing upgrades (which is as it should be),
I have to wreck the system, by removing the desktop system and the
operating system core.

So, how do I remove

Faulty Software Updater on 16.04


I am running UbuntuMATE 16.04 on at least two different computers.

For a while now, the Software Updater (which reappears daily, due to
using the panel applet) shows a window with the heading "Not all
updates can be installed".

The window does not provide a button "Show details", and, does not
allow me to copy and paste the text that is displayed in the window.

The only options available (apart from simply clicking the cross box,
to close the window, which I have had to do, each time the window
appears, as no other safe option is available) do not provide safe

Ubuntu Linux and firewalling and dual NIC's


I have a firewall/gateway computer, that has two network cards, and we
are soon to change from ADSL to the (Australian) soupy-doupy NBN thing
with supposedly higher data transmission speed capabilities, which
means a new modem/router thing with which to interface, and so, new
settings (or so, I expect), which means, in the context of the status
of the firewall/gateway computer, replacing the operating system and
firewall software.

I have thus far, used Ubuntu Linux only as a workstation operating
system, which does not involve two network interfaces; two NIC's, and
so I need to know w

How to obtain list of installed packages


I believe that this question gets asked from time to time, but I do
not know that a solution has been found.

The question is this; does a utility exist, that can be ran, to
produce a list of installed packages, in a way that can be used by a
user (system administrator), to perform a system rebuild, so as to,
after installing the system again, ensure that all of the optional
packages that were previously installed, are again installed in the
new system installation?

Utilities apparently missing from Ubuntu15.10


I have just installed UbuntuMATE 15.04 amd64 version, to replace
Ubuntu.10.04 on a computer upon which I had been running Debian 6, so

Having just got the UbuntuMATE 15.10 installation set up and running,
I can not find the Software Centre utility, or Synaptic, for finding

Are these utilities still available?

If so, why is the Software Centre not included in the installation iso CD image?

Query about monitoring unknown Internet traffic


Last night, this computer, running UbuntuMate 1504, started sending

At present, all that I can do, to regulate the data transmission, is
to pull the (Internet connection) plug on the system.

How to change scrolling in Ubuntu


In Ubuntu, in some applications, the standrad scrolling method, is
applicable, along the side or the bottom of the scroolable area, is a
bar thing, that can be drawn, with the pointing device, to the
position that the user wants, and, in that, the drawing is
continuously variable.

Howebver, in Ubuntu, the system scrolling method, involves not a
visble scrolling thing to be drawn with the pointing device, to where
the user wants, but is a discrete thing, that, when the user positions
the cursor over an appropriate edge of the "scrollable" area, a thing
