I tested the upgrade again in Virtualbox. It did not solve the issue for me.
I have first activated -proposed in 10.04, then installed all available upgrades, and then launched the dist-upgrade After the dist-upgrade, the package indicator-appmenu is not installed and global menu is not activated. I attach the dist-upgrade/apt.log, where there are the following lines : Investigating (0) indicator-appmenu [ i386 ] < none -> 0.3.97-0ubuntu1.2 > ( gnome ) Broken indicator-appmenu:i386 Conflicts on libdbusmenu-glib1 [ i386 ] < 0.2.9-0ubuntu3.1 > ( libs ) (< 0.3.7) Considering libdbusmenu-glib1:i386 9 as a solution to indicator-appmenu:i386 3 Holding Back indicator-appmenu:i386 rather than change libdbusmenu-glib1:i386 ** Attachment added: "dist-upgrade/apt-log with -proposed enabled and version 0.3.97-0ubuntu1.2" https://bugs.launchpad.net/ubuntu/+source/indicator-appmenu/+bug/1034668/+attachment/3317090/+files/apt.log ** Tags removed: verification-needed ** Tags added: verification-failed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1034668 Title: Upgrade from Lucid to Precise does not install packages for Global Menu: indicator-appmenu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-appmenu/+bug/1034668/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
