Ubuntu 14.04 update wants to remove ubuntu-mate-desktop?

  • 772

I've seen Apt wants to remove ubuntu-mate-desktop, but this is different.

I use MATE desktop, and my Ubuntu is:

$ uname -a
Linux MYPC 4.2.0-36-generic #42~14.04.1-Ubuntu SMP Fri May 13 17:27:22 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
$ cat /etc/issue
Ubuntu 14.04.4 LTS \n \l
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.4 LTS
Release:    14.04
Codename:   trusty

Just today, I was thinking of doing an upgrade:

Oh, I thought, some packages are held back, why not update them with dist-upgrade?

B... but wait, I do not want to remove ubuntu-mate-desktop, I am using it! So what is going on, why does the update want to remove ubuntu-mate-desktop? How should I do the update, so I keep ubuntu-mate-desktop?

EDIT: I let the dist-upgrade go so ubuntu-mate-desktop is removed; thankfully it is just a metapackage, so I still have MATE running after reboot, but now I get:

$ sudo apt-get install ubuntu-mate-desktop

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ubuntu-mate-desktop : Depends: compiz-mate but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Why, oh why, ... can't compiz-mate and compiz-gnome just coexist? Why is it necessary to break my system? ...
