Fresh install of Kubuntu 16.04 breaks when using Dutch language

[DeathByDenim]

The kde-l10n-nl package conflicts with plasma-desktop and plasma-desktop-data.
Unfortunately, on a fresh install of Kubuntu 16.04 from the iso, this package is automatically installed and thus plasma-desktop and plasma-desktop-data are uninstalled. This results in an error after logging in for the first time, saying that the necessary packages are missing.

Weirdly enough, packages such as kde-l10n-de do not have this problem.

So to reproduce (in Virtualbox):
1. Create new virtual machine
2. Install Kubuntu 16.04 from ISO
3. Choose "Nederlands" (Dutch) as the language.
4. Finish installation and restart.
5. Log in for the first time and observe the error.

Workaround is to use Alt+F2 to open krunner, and start a terminal session from there. Then install plasma-desktop and plasma-desktop-data again with apt and reboot. Now everything works fine again.

Status changed to 'Confirmed' because the bug affects multiple users.

I started recovery mode and reïnstalled kubuntu-desktop. Everything does work again (except some really weird glitching in muon-discover and kubuntu asking to install the "KDE Dutch language pack" frequently.).

I already tried different ISO's and USB sticks. The problem persists.
Not planning to upgrade any other Kubuntu installation in a while.

This package of course also creates problems on an upgrade. I found it in Synaptic as 'out of date or manually installed'.
When trying to update Synaptic suggests to uninstall plasma-desktop and plasma-desktop-data.

I cancelled this and instead removed kde-l10n-nl.

Lucky guess, all continous to work fine after this.

This bug is a duplicate of bug 1572494, not of bug 1558401 imo

sudo add-apt-repository -y ppa:kubuntu-ppa/staging-misc
sudo apt-get update
sudo apt-get -y install kde-l10n-nl
sudo apt-get -y install plasma-desktop

since not only the install but also update fails this bug leads either to a completely unusable system or to a system without security updates. Can it get any worse?
