Good evening Wayne,
My advice would be for you to wait a day or two. I went ahead and dist-upgraded (I don't mind living on the edge) and apt-listbugs reported this...

Code: Select all

serious bugs of libqtdbus4 (-> 4:4.8.2+dfsg-7) <unfixed>
 #697147 - libqt4-dbus: Fails to upgrade from 4:4.8.2+dfsg-6
   Merged with: 697159
Summary:
 libqtdbus4(1 bug)
Are you sure you want to install/upgrade the above packages? [Y/n/?/...] 

I said yes, which I don't advise you to do :)
and then ran into a couple of files with unmet dependencies and had to run

Code: Select all

apt-get -f install

Like I said, I am just playing guinea pig, but wouldn't advise anyone else to do the same.
So far I haven't noticed any issues, but that doesn't mean I wont run in to some problem later.
Best for you to wait, better to be safe than sorry. :D

Thanks swftech for your advice and some details.

Apparently you might have d-u earlier than my time.
Because when I tried, there is no apt-listbugs, I guess Debian maintainer (?) had already held back those qt4 's

Since I have created an iso with bbqsnapshot, just in case I need to use it, out of curiosity, I felt brave enough to just 'live in the edge' for this moment ( eventhou it sounds like a bad idea, but life is like that? I need experiments so as to learn also..)

Just in case I need to return for help, I captured the terminal output and put here..

Good thinking wayne using BBQ snapshot first :) Not sure why they are being held back if running dist-upgrade. did you simply use "upg" command or "apt-get dist-upgrade"?

[pidsley]

If everything is working, I would leave things alone -- this may be resolved by the next time you need to upgrade. In the future, swftech gives good advice to wait a day or two when you see a bug like this.

When you get a bug notice like this, you can always go to the Debian web site and read the actual bug to see if you can understand what's happening.

Go here, and enter the bug number: http://www.debian.org/Bugs/

and you will end up here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=697147

In this case, this looks like the problem:

libQtDBus.so.4 was split from libqt4-dbus to libqtdbus4, so, for now, to
install libqtdbus4 you must upgrade or remove libqt4-dbus first (with
proper --force dpkg args).

Again though -- if your install is working, I would leave it alone, unless you have a very good reason to install libqtdbus4. Any time anyone mentions an argument called "force" I am very wary of using it. Note that they say "for now" -- this implies (at least to me) that the "bug" will be fixed.

[machinebacon]

Right.

Sometimes people report a bug for the sparc or ARM and it gets displayed in apt-listbugs, too. Other bug reports date back months (literally) and were not closed or couldn't be reproduced. The best is really to check under what circumstances the bugreport was filed (full KDE install? are maybe dependencies of other packages locking down something?) and to wait a few days. As you can see, they fixed 2 packages in the 6 hour cycle.

[swftech]

As usual, pidsley and machinebacon make some extremely valuable and valid points. :D

Oh, and as I always have fun saying, if you do decide to "force" upgrade and it breaks...You can keep the pieces :P

[ivanovnegro]

A bit late but I will add my mustard.

The little Qt transition is over and it is safe to d-u. That is the beauty of Sid, problems get actually fixed.

As I was on vacation I had a clean d-u without even noticing there was this Qt problem.

[wayne]

thanks pidsley, swftech and ivan for your replies

my xfce is fully d-u.
