unmet dependences wit QT packages- caused by skype

[Carla Sella]

I upgraded my PC (http://wiki.ubuntu-it.org/CarlaSella/lshw) from Precise Pangolin to Quantal Final.
After reboot I got a message in update manager:
"An error occured, please run package manager from the right-click menu or apt-get in a terminal to see what's wrong.
The error message was: Error: BrokenCount > 0: This usually means that yout installed packages that have unmet dependencies".

So I ran apt-get update and apt-get upgrade in terminal and got this message:
"The following packages have unmet dependencies:
libqtgui4:i386 : Depends: libtiff5:i386 (> 4.0.0-1~) but it is not installed
libtiff4:i386 : Depends: libjbig0:i386 but it is not installed "

So I ran apt-get upgrade -f and solved the problem.

I have a screenshot of Update-manager's message.

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the log files from '/var/log/dist-upgrade/' to this bug report as separate attachments (not pasted into comments or tar/zip-ed)? Thanks in advance.

[Carla Sella (carla-sella)]

Ok here they are, I am attaching all the files found in the /var/log/dist-upgrade directory.

[Carla Sella (carla-sella)]

There is also a file called apt-clone_system_state.tar.gz, should I unzip it and upload it' content?

[Carla Sella (carla-sella)]

In the var/log/dist-upgrade directory there is another directory: 20121012-2151 I am now attaching the files in it.

[Paul Fredrickson (paul-fredrickson)]

This is also affecting me. It's unclear if the "apt-get upgrade -f" is the accepted work around or not. I am hesitant to do this on my machine, since I am actually running amd64, so I find it weird that it is depending on the i386 versions of anything.

In addition to the two dependencies mentioned by Carla, I get the same unmet dependencies by libcolord1:i386 (missing liblcms2-2:i386), libgdk-pixbuf2.0-0:i386, libsane:i386, and libsdl-image1.2:i386 (all missing libtiff5:i386)

Hi Carla,

to answer your question from comment #10.

Yes, an attaching would be greate. This file gives us the ability to recreate your system automatically for reproducing.

I have inverstigated the logs.

In

apt.log there is :

This repeats in different flavours many many times.

The Qt packages are not the real problem here.

It is the skype pack that makes the trouble.

The upgrader misidentify this a bit.

It seems to be that the upgrader is not allowed to remove the skype package, so it try to figure arround with the QT packages to resolv the dependences of skype.

In main.log there is

2012-10-12 22:41:39,155 DEBUG check if patch '_usr_bin_pycompile.b17cebfbf18d152702278b15710d5095.97c07a02e5951cf68cb3f86534f6f917' needs to be applied

which I have seen short ago in a different report(different user).

I am a bit obfuscated about.

This ends with:

Hello Melchiaros, here is my apt-clone_system_state.tar.gz file, hope it is still ok after all this time :).

[Brian Murray (brian-murray)]

The first errors that we see from dpkg are the following:

Setting up libjbig0:amd64 (2.0-2ubuntu1) ...
dpkg: error processing libjbig0 (--configure):
 no package named `libjbig0' is installed, cannot configure
Setting up libtiff5:amd64 (4.0.2-1ubuntu2) ...
dpkg: error processing libtiff5 (--configure):
 no package named `libtiff5' is installed, cannot configure

and that is probably the real source of the problem.
