package kaccounts-providers (not installed) failed to install/upgrade: trying to overwrite '/etc/signon-ui/webkit-options.d/www.facebook.com.conf', which is also in package account-plugin-facebook 0.12+16.04.20160126-0ubuntu1

I was trying to replace Unity with KDE. The original disk was from Linux Format DVD211.

Unity is very annoying with animation that cannot easily be switched off and slows everything down. Terminal also represented a 'p' as a heavy underscore (xterm did not).

I will replace the whole system with a clean KUbuntu download to see whether that is any better.

This is to upgrade from a very elderly Kubuntu 8.04 LTS 32 bit system which is well past its expiry date.
