As I see the problem is in Ubuntu version of the package plasma-workspace: http://anonscm.debian.org/cgit/pkg-kde/plasma/plasma-workspace.git/tree/debian/control?h=kubuntu_stable
Probably it should be sync with Debian version of the package. In particular: http://anonscm.debian.org/cgit/pkg-kde/plasma/plasma-workspace.git/tree/debian/control#n162 ... Package: plasma-workspace ... Breaks: plasma-systray-legacy, ... Replaces: plasma-systray-legacy, ... xembedsniproxy module was included into plasma-workspace since release 5.5.0, so a separate package plasma-systray-legacy is not required anymore and it might be freely removed from Ubuntu >= 16.04. ** This bug is no longer a duplicate of bug 1573787 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 ** Package changed: xembed-sni-proxy (Ubuntu) => plasma-workspace (Ubuntu) ** Changed in: plasma-workspace (Ubuntu) Status: New => Confirmed ** Tags removed: amd64 apport-package ** Tags added: xenial -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to plasma-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1575734 Title: package plasma-systray-legacy (not installed) failed to install/upgrade: trying to overwrite '/etc/xdg/autostart/xembedsniproxy.desktop', which is also in package plasma-workspace 4:5.5.5.2-0ubuntu1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plasma-workspace/+bug/1575734/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
