In response to ouroumov (message 9):
“Please post the output of: inxi -r”
I tried to, but got a message saying that I could only create 2 links in a post, and the aforementioned output was/is full of links, the first two being
Repos: Active apt sources in file: /etc/apt/sources.list
deb cdrom:[Ubuntu 16.04 LTS Xenial Xerus - Release amd64 (20160420.1)]/ xenial main restricted
deb http://nz.archive.ubuntu.com/ubuntu/ xenial main restricted
How can I show the full output?
Even inside code blocks? ( the </> symbol )
Mate 1.16 is under development and will have bugs in it. I do not see how you managed to install this.
I think its best for you to reinstall.
The “code blocks” business was what I didn’t (and needed to) know.
But I cannot get it to work. I clicked on the “</>” symbol before pasting in the output of “inxi -r” but this didn’t help.
Can you give me more explicit instructions, or point me to where I can find them please?
Can you give me a recipe for “reinstalling”?
Do I need to/should I remove/purge the currently installed version first?
If so, what is the recipe? “sudo apt-get … <what?>” ???
Do you wish to keep Ubuntu (Unity)? Do you have windows installed? What about just going with a Ubuntu Mate install?
Maybe do a bit of reading first.
Install Ubuntu (Mate) using "Something else" method

rolf:
what is the recipe?Do you wish to keep Ubuntu (Unity)?
Yes.
Do you have windows installed?
No. I don’t do Windoze!
What about just going with a Ubuntu Mate install?
Sure. But I’ll have to find out how.
Maybe do a bit of reading first.
OK.
The following material appears to imply that you are suggesting that I
re-install Ubuntu, rather than just reinstalling Mate. Is this correct?
The choice is totally up to you.
@rolf Can you give us a screenshot of Software & Updates application at the Other Software tab (make sure you expand the window so that all the repositories are shown)?
Any chance that you are using this ppa: https://launchpad.net/~jonathonf/+archive/ubuntu/mate-1.16? This is the only way that I know of how to install MATE 1.16 on Ubuntu 16.04.
Can you give us a screenshot of |Software & Updates| application at the
|Other Software| tab (make sure you expand the window so that all the
repositories are shown)?
Here's the follow-up with "bottomhalf.png".

Maybe this would be of help. Open a terminal and enter (one line at a time):
cat /etc/apt/sources.list > source-txt
ls /etc/apt/sources.list.d/*.list >> source-txt
sudo apt-get -f install >> source-txt
sudo apt-get install pastebinit
cat source-txt | pastebinit
Wait and it will print back a link (url) while you are still in terminal, please post that link here.

Followed instructions. The result is:

I note that when I did
I got a number of warnings:

The “configured multiple times” issue doesn’t surprise me, the way I’ve
been mucking about, not really knowing what I’m doing.
Thanks for taking an interest in my problem.

First problem:
Line #1 needs to be commented (#) out.
deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted
needs to read
#deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted
So open your editor as superuser:
gksudo pluma /etc/apt/sources.list
and # that line out.
Sencond problem; line 61
deb http://archive.canonical.com/ precise partner
Also needs to be commented out.

If you want to go back to MATE 1.12 (this will probably solve your problems) then:
install ppa-purge by:
sudo apt install ppa-purge
Purge jonathonf mate ppa by:
sudo ppa-purge ppa:jonathonf/mate-1.16
Finally run these commands to make sure everything is ok (tell us if you see any errors):
sudo apt update
sudo apt dist-upgrade
The latest MATE version available for xenial that will cause 0 problems is MATE 1.14 built with gtk2, which you can get from the official xenial ppa: https://launchpad.net/~ubuntu-mate-dev/+archive/ubuntu/xenial-mate. So, if you want to update MATE use it instead.

Sad to say I got stopped at Step 2. I have pasted the output from
running this command into a file “errMess.txt” and attached it.
I hope you can make some sense of it and advise me as to how to get
around the problem. Sorry to be such a nuisance.

Go on to step three. Can you update and upgrade?
sudo apt update && sudo apt dist-upgrade
If that works, then reboot.

|sudo apt update && sudo apt dist-upgrade|
Did that. Not sure that it “worked”. There was no mention of Mate in
the list of packages being upgraded. There was a lot of stuff in the
output that looks ominous to me, but I don’t really understand it.
I have captured and attached the screen output of the dist-upgrade command.
If that works, then reboot.
Despite not being sure that it had “worked”, I rebooted. No effect
seems to have resulted. I.e. I still seem to be running Mate 1.16.
Wouldn’t it be sensible to purge Mate
sudo apt-get purge mate
(or something like that) and then re-install, making sure that I am
installing version 1.14 rather than 1.16? How can I make sure of this last?
Thanks for your patience.
cheers,
Rolf
When you hilight something for a reply please do not include user name. It prints out wrong^^^
Sounds like the update completed, so that is now good. Yes m1.16 is still installed, the above command that @ThanosApostolou posted should remove it and return you to the 1.12 desktop.
Before you do that though, try this. I also run the m1.16 desktop and found it works best on the GreenLaguna theme.
Try that theme.
It’s not too bad, but still messes up the window indicators in the bottom panel. I’m going to try to go back to Mate 1.12, following the instructions from @ThanosApostolou .
Thanks.
