After todays dist-upgrade to Plasma 5.9 the Neon packages break KDE PIM applications with following error: "kmail: error while loading shared libraries: libQt5WebEngineWidgets.so.5: cannot open shared object file: No such file or directory" This is with version: Package: kmail Version: 4:16.12.1+p16.04+git20170129.1347-0 Manually installing the package that contains the library (and others) fixes this. The package is "libqt5webenginewidgets5" and it seems that none of the PIM packages depend on it so it does not automatically get pulled in on a dist-upgrade: $ apt-cache rdepends libqt5webenginewidgets5 libqt5webenginewidgets5 Reverse Depends: libqt5webenginewidgets5-dbgsym qtwebengine5-examples qtwebengine5-examples qtwebengine5-examples qtwebengine5-dev qtwebengine5-dev qtwebengine5-dev libqt5webenginewidgets5-dbgsym libqt5webenginewidgets5-dbgsym
Forgot to add the package version for libqt5webenginewidgets5: 5.7.1+dfsg-2+16.04+build15
It seems now that the latest update, i.e. libqt5webenginewidgets5 5.7.1+dfsg-2+16.04+build16 is being depended by Akregator at least, which should fix that one from crashing: apt-cache rdepends libqt5webenginewidgets5 libqt5webenginewidgets5 Reverse Depends: libqt5webenginewidgets5-dbgsym qtwebengine5-examples qtwebengine5-examples qtwebengine5-examples qtwebengine5-examples qtwebengine5-examples qtwebengine5-dev qtwebengine5-dev qtwebengine5-dev qtwebengine5-dev qtwebengine5-dev libqt5webenginewidgets5-dbgsym libqt5webenginewidgets5-dbgsym libqt5webenginewidgets5-dbgsym libqt5webenginewidgets5-dbgsym akregator However, Kmail and Kontact should probably also depend on it.
Closing this due to it being too old and not relevant anymore.
