--- Comment #3 from Nick <ndor...@gmail.com> --- Could you please give me an email for the distro problem ? Thanks ------------- However , it seems that the KDE packaging is the issue . After I did some checking of the versions of the KDE/akonadi/libKF5 components and updating them [ manually ! ] to be at the same level I got the kontact working again . Here is what I've done .......... Continued to check [ via yast ] some version between different components like kleopatra5 16.08.2.-1.1 libkleo 17.04.1-47.1 then upgrade to kleopatra 17.04.1-21.1 which triggered the upgrade kleopatra-lang 17.04.1-21.1 I discovered many more in the same category . All point to KDE packaging . I use Software Update" wizard to get notifications when updates are available. Then , I use sudo zypper -up l to updatae/upgrade my machine . It is supposed that the zypper resolves the inter-packages relationships and selects the packages that match those relationships . Explaining why kleopatra remains at 16.8 level while libkleo is upgraded to 17.04 point to the correctness of inter-packages relationships' definitions . I noticed that some undefined symbols were resolved and another new ones were the new culprits [ mainly in libKF5* packages ] . I continued with this process until both kontact/kmail failed without displying an error window . Starting them from konsole gave the below symptmos ..... that point now to akonadi ! The messages are provided at the end of this file. I did the same thing, as above, for akonadi [ some packages were at 16.8 other at 17.04 ] and I got allmost of them to 17.04 .... version . After many yast updates finally I got kontact stating as before . ps -ef | grep kontact <uname> 1028 4647 0 15:44 ? 00:00:00 http.so [kdeinit5] http local:/run/user/1000/klauncherTJ4648.1.slave-socket local:/run/user/1000/kontactP28986.5.slave-socket <uname> 1029 4647 0 15:44 ? 00:00:00 http.so [kdeinit5] http local:/run/user/1000/klauncherTJ4648.1.slave-socket local:/run/user/1000/kontactV28986.6.slave-socket <uname> 1031 4647 0 15:44 ? 00:00:00 http.so [kdeinit5] http local:/run/user/1000/klauncherTJ4648.1.slave-socket local:/run/user/1000/kontactM28986.7.slave-socket <uname> 1033 4647 0 15:44 ? 00:00:00 http.so [kdeinit5] http local:/run/user/1000/klauncherTJ4648.1.slave-socket local:/run/user/1000/kontactr28986.8.slave-socket <uname> 1038 4647 0 15:44 ? 00:00:00 http.so [kdeinit5] http local:/run/user/1000/klauncherTJ4648.1.slave-socket local:/run/user/1000/kontactb28986.9.slave-socket <uname> 1039 4647 0 15:44 ? 00:00:00 http.so [kdeinit5] http local:/run/user/1000/klauncherTJ4648.1.slave-socket local:/run/user/1000/kontactf28986.10.slave-socket <uname> 1052 4647 0 15:44 ? 00:00:00 http.so [kdeinit5] https local:/run/user/1000/klauncherTJ4648.1.slave-socket local:/run/user/1000/kontactg28986.11.slave-socket <uname> 1055 4647 0 15:44 ? 00:00:00 http.so [kdeinit5] https local:/run/user/1000/klauncherTJ4648.1.slave-socket local:/run/user/1000/kontactz28986.12.slave-socket <uname> 28986 4647 0 15:20 ? 00:00:14 /usr/bin/kontact <uname@hostname>:~> kontact [0518/104345:ERROR:nss_util.cc(839)] After loading Root Certs, loaded==false: NSS error code: -8018 org.kde.pim.webengineviewer: It's not necessary to check database now org.kde.akonadi.ETM: GEN true false false org.kde.akonadi.ETM: collection: QVector() org.kde.akonadi.ETM: org.kde.pim.webengineviewer: Database already initialized.
