Upgrade paths from UbuntuMATE 16.04.x and 18.04.x to 19.10

Bret Busby-2
Hello.

I am running UbuntuMATE 16.04.x on three computers with nVIDIA
thingies, and 18.04.x on a different system.

In having just found and read the Release Notes (as they are at this
stage) for UbuntuMATE 19.10, as published at
https://ubuntu-mate.org/blog/
with the expected release date being 2019-10-17 (and, funnily enough,
not 2019-10-19), and, with the expected advantages for people with
nVIDIA thingies, apart from the other expected benefits of the upgrade
to 19.10, for UbuntuMATE users, I am intending to upgrade all my
computers to 19.10, when it is released.
What I am wondering, is the req

This is the second attempt at composing the message - the <expletive>
thing sent itself, while I was trying to compose it.


What I am (and was) wondering, is the required upgrade path, for each
of the versions.

I am assuming (but am not sure) that I can upgrade directly from
18.04.x. to 19.10.

Do I need to upgrade each of the 16.04.x systems, to 18.04, thence to 19.10?

Or, do I need to perform intermediate upgrade steps, with each of the versions?

I assume that, once upgraded to 19.10, I will, when it becomes
released, be able to upgrade thence to 20.04, and, return to the LTS
upgrade cycle.

Clarification as to whether my assumptions and understandings, in
this, are correct, would be appreciated.

Thank you in anticipation.

I don't think that is correct.  Technically the supported release path
from 18.04 to 19.10 requires you to go 18.04 -> 18.10 -> 19.04 ->
19.10.

You can upgrade from one LTS release directly to the next LTS release
(e.g., 16.04 -> 18.04 is supported, and 18.04 -> 20.04 will be
supported next spring).  But for non-LTS releases the supported upgrade
path is to go through each one.

I guess ultimately if you start the upgrade tool with the -d option to
allow development releases, then you can upgrade to any release offered
to you there.  I suspect that if you run that on 18.04 it won't offer
you 19.04 or (when released) 19.10.

Yes, when 20.04 LTS is released it will be supported to upgrade
directly to it from both 19.10 and from 18.04 LTS.

True. In this scenario I would consider just doing a clean install.
I've upgraded through several releases this way before with luck, but
it might be easier to just install a fresh system from the release
candidate images.

Also true, but the supported upgrade path from 18.04 to 20.04 will only
be opened after the first point release, which will happen a few months
after release (so not in the spring).

The work of Annie Ominous, appears to have been done by the software updater.

On one of my 16.04.x systems, I tried the following upgrade path.

1. Using the Software Updater, check and install all updates, to make
the system fully updated for 16.04.x. That (appears to have) worked.
Rebooted.

2. Using the Software Updater, which, upon rebooting, displayed the
notification that an update to 18.04 is available, selected the
Upgrade System (to 18.04) option. That appeared to have worked, with
lots (about 266) of packages to be removed.

Rebooted.

Broken.

Upon rebooting, I get the GRUB menu, either wait for it to timeout and
boot by default into Ubuntu, or hit <Return> with the default
highlighting being for Ubuntu, and I get, first, the terminal level
login displayed, then the screen goes black, then I get, in the middle
of the screen, the UbuntuMATE logo, with the five dots below it, with
them taking turns to change from white to green and back again, below
the logo.

Then, after a minute or two of that, the screen goes black, and stays black.

After at least en minutes of waiting, with no visible change, I use
<CTRL><ALT><F1>, get console mode, which shows me that the system is
now 18.04.3 LTS.

I can log in at the console mode, in either of two user accounts, and,
upon running
sudo apt check
no problems are shown.

At the console prompt, when logged in, if I enter
startx
I get a screen with, and, only with, a default green background, displayed.

If I then enter <CTRL><ALT><F7> I again get the black screen.

With the green background screen, if I use the non-dominant mouse
button, a menu dialogue box is displayed, but no option that appears
to me to be useful in this context, is displayed.

The computer to which this applies, is the computer to which my
previously stated problem of losing use of the GUI for me as the
primary user, due to a panel problem, then, being able to add a second
user, and, logging in as the second user, gave me access to the GUI,
as the second user, also applies, so I do not know whether this
upgrade problem, is related to that problem.

After the failed upgrade, I can no longer reach a GUI login screen,
upon booting - the GUI appears to have been destroyed by the upgrade
from 16.06.x to 18.04.3 .

10-20 years ago, from memory, a command line procedure existed, for
upgrading from one version to the next version (in this case, for
example, trying to upgrade from 18.04.3, to 18.10.x, to find whether
that could solve the problem of the lost GUI), but, I do not remember
what was the command line procedure for doing that.

So, how can I fix this, and, regain my GUI, to get the computer working again?

System (version number) updates appear to be increasingly troublesome.

Thank you in anticipation.

You mean "do-release-upgrade" ?

My two-penn'orth:

Don't.

18.04 is an LTS release.

19.10 is not. The _next_ one is 20.04 and that will be an LTS.

You will be able to go direct from 18.04 to 20.04.

You cannot go direct from 10.04 to 19.10 because 19.10 will be a
normal short-term release.

P.S. Gmail sometimes decides to send all on its own for me, too, and
even after 15 years of use, I don't know what I press to make it do
it. Most irritating.

I had been considering also, the prospect of 16.04 -> 18.04 -> 20.04,
given that it is just another six months until the expected release of
20.04, which would include the enhancements contained in 19.10, and
more; sticking with just the LTS versions, as I had done for the last
few years.

Due to what happened with the botched attempt at upgrading from
16.04.x to 18.04.3, I am inclined to avoid as many version upgrades,
as possible, and so will now probably stick with the LTS versions.

Now, I need to get the system with the botched 16.04.x -> 18.04.3
upgrade, fixed, before considering any further version upgrades...
