Hello!

I have at school about ~50 machines with KDE Neon (based on Ubuntu 18.04) as main system. I configured Plasma Desktop with KDE Kiosk nicely (added some restrictions) and added some external repositories (like fresh LibreOffice PPA / Wine PPA). Users of these machines are not technical people (teachers, students) and because of this I set unattended-upgrades (/etc/apt/apt.conf.d/50unattended-upgrades) to have KDE Neon up to date. Everything is working fine until "neon-settings" package is being updated. Always when this package is being updated - information message from this package is showing that:

Code: Select all

...
Configure package neon-settings (0.0+p18.04+git20190506.0955) ...
Neon disables unattended-upgrades.
  To enable them you need to explicitly set unattended-upgrades/enable_auto_updates AND have it /marked/ as seen in debconf.
  `dpkg-reconfigure unattended-upgrades` allows configuration of the package.
...


and after this operation (configuration of this package) file: /etc/apt/apt.conf.d/20auto-upgrades is being deleted. This cause for me big problem, because suddenly all machines are no more being updated. I have start from scratch create/copy from backup 20auto-upgrades file and then unattended-upgrades are working again - till the next neon-settings package update - it is like "vicious circle".
I tried for example create /etc/apt/apt.conf.d/02periodic instead of /etc/apt/apt.conf.d/20auto-upgrades - this solve the problem with file deletion but it is not solving the problem with the proper update (on some machines this is working on some not - I don't know why and where to debug this).

My question is, can I do something with this situation?

Regards,
Rob.
