The solution is indeed to install the qt5-default package. Maybe this package could be added as a dependency in newer releases?
There is also perhaps an upstream bug where qtchooser could try the "other" qt version if one fails. (I had installed qdbus5, and qtchooser was trying qdbus4, which was not installed or wanted.) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qt4-x11 in Ubuntu. https://bugs.launchpad.net/bugs/1251178 Title: qdbus and qdbusviewer crash with "No such file or directory" Status in qt4-x11 package in Ubuntu: Confirmed Status in qtchooser package in Ubuntu: Confirmed Bug description: Release: Ubuntu 13.10 (32-bit) Package versions: qtdbus 4:4.8.4+dfsg-0ubuntu18 qtchooser 26-3ubuntu2 Expected behavior: The `qdbus` program runs, as does the related program `qdbusviewer`. Actual behavior: If I run the `qdbus` program, it always crashes: user@host:~$ qdbus --help qdbus: could not exec '/usr/lib/i386-linux-gnu/qt5/bin/qdbus': No such file or directory The `qdbus` executable is actually: user@host:~$ ls --full-time $(which qdbus) lrwxrwxrwx 1 root root 9 2013-08-07 14:48:40.000000000 +0000 /usr/bin/qdbus -> qtchooser Note that `/usr/lib/i386-linux-gnu/qt4/bin/qdbus` exists and seems to work if I invoke it directly. There's a `qdbus-qt5` package in the universe repository. It was not pulled in as a dependency, but manually installing it fixes the issue. Therefore it's either a packaging error or a bug in qtchooser. A similar thing happens if I run `qdbusviewer`: user@host:~$ qdbusviewer qdbusviewer: could not exec '/usr/lib/i386-linux-gnu/qt5/bin/qdbusviewer': No such file or directory except that installing `qdbus-qt5` doesn't fix the issue.
