Public bug reported: Not sure how to file this: it's for the do-release-upgrade process for kubuntu from 12.10 to 13.04.
After upgrading the login manager came up fine. When logging in there was a message about qdbus from startkde: if qdbus >/dev/null 2>/dev/null; then : # ok else echo 'startkde: Could not start D-Bus. Can you call qdbus?' 1>&2 test -n "$ksplash_pid" && kill "$ksplash_pid" 2>/dev/null xmessage -geometry 500x100 "Could not start D-Bus. Can you call qdbus?" exit 1 fi The xmessage one. invoking qdbus by hand on a text console gave a message I can't remember. Strace seemed to show that it was looking for something it did not find. This led me to look at qtchooser which also did not work. "qtchooser -list-versions" listed nothing. I tried to use apt-file to find the directories it looked in (found by strace). Then I tried to install qt5-default. Then the message changed to qdbus binary missing from some library directory specific to qt5. When i installed qt4-default and reinstalled qdbus it was possible to log in. Kind of high threshold to get the upgraded machine to work. Now upgrading a kubuntu VM with much fewer packages installed, I'll post here what I learn.
