I did this instead : sudo sed -i s/oneiric/precise/ /etc/apt/sources.list sudo apt-get dist-upgrade
Les paquets suivants contiennent des dépendances non satisfaites : libopencv-core-dev : Casse: libcv-dev (< 2.3.1-1) mais 2.1.0-7build1 devra être installé sudo apt-get remove libcv-dev sudo apt-get dist-upgrade Des erreurs ont été rencontrées pendant l'exécution : /var/cache/apt/archives/libgmerlin-dev_1.0.0~dfsg-13_i386.deb /var/cache/apt/archives/default-jre-headless_1%3a1.6-43ubuntu2_i386.deb Then I went in Synaptic to force upgrade of jre-headless (I don't know what was wrong). The rest of the package stuff went fine. Then the system refused to reboot. I had to go to a shell and do sudo reboot Then it would stop shutting down at 4/5 (in terms of dots on the shutdown screen that prevents users from knowing what's going on). So I just held the POWER button for 4 seconds and pressed again. After that it seemed to work fine, except that the Launcher contains no apps anymore, no app categories either, and is missing 3 icons at the bottom (replaced by generic paper sheet icons). And except that the applets (or whatever they are called now) all disappeared. I didn't remember what to do to switch keyboard layouts... I found I could do it by starting gnome-control-center from a shell. I don't know of a similar thing to replace the cpu frequency chooser applet I had installed. I try running indicator-cpufreq-selector. dbus.exceptions.DBusException: org.freedesktop.DBus.Error.AccessDenied: Connection ":1.68" is not allowed to own the service "com.ubuntu.IndicatorCpufreqSelector" due to security policies in the configuration file That's all for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027343 Title: can't upgrade from 11.10 to 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1027343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
