[gentoo-user] Uncle: qt-*:4 dependencies/blocks preventing world update

[Alan E. Davis]

[-- Attachment #1: Type: text/plain, Size: 1869 bytes --]

I've tried alot of things, but I give up.  Can someone help me with the knot
of dependencies that has been holding my system in hostage from any attempt
to update world, for weeks now?

This message asked if I want to merge these packages:

!!! The following update(s) have been skipped due to unsatisfied
dependencies
!!! triggered by backtracking:

x11-libs/qt-assistant:4
x11-libs/qt-svg:4
x11-libs/qt-test:4
x11-libs/qt-script:4
x11-libs/qt-webkit:4
x11-libs/qt-opengl:4

Would you like to merge these packages? [Yes/No]

Here are the blocks:

Total: 70 packages (54 upgrades, 9 downgrades, 6 new, 1 reinstall), Size of
downloads: 227,710 kB
Conflict: 22 blocks

!!! One or more updates have been skipped due to a dependency conflict:

x11-libs/qt-gui:4

  ('ebuild', '/', 'x11-libs/qt-gui-4.5.3-r1', 'merge') conflicts with
    ~x11-libs/qt-gui-4.5.2[-debug] required by ('ebuild', '/',
'x11-libs/qt-webkit-4.5.2-r1', 'merge')

x11-libs/qt-sql:4

  ('ebuild', '/', 'x11-libs/qt-sql-4.5.3', 'merge') conflicts with
    >=x11-libs/qt-sql-4.5.0:4[mysql] required by ('installed', '/',
'app-office/akonadi-server-1.2.1', 'nomerge')

x11-libs/qt-core:4

  ('ebuild', '/', 'x11-libs/qt-core-4.5.3-r1', 'merge') conflicts with
    ~x11-libs/qt-core-4.5.2[qt3support,-debug] required by ('ebuild', '/',

    ~x11-libs/qt-dbus-4.5.2[-debug] required by ('ebuild', '/',
'x11-libs/qt-gui-4.5.2-r2', 'merge')

I think one of the problems is I installed KDE 4.3.X and all of that may
need rebuilding.

I tried installing a qt overlay.  I tried unmasking a more advanced masked
qt.  I've seen a number of messages, some of them from a few months back,
recommending several magical incantations.  Nothing seems to get me beyond
this knot.

Thank you,

Alan

but that question has been answered many times. Have you tried googling?

Please read your portage news, especially "2009-09-27-qt_use_changes". See 
also this weeks thread with subject "Confusion".

I have read a number of different explanations and suggestions, some of them
regarding an earlier, yet similar, tanglement between versions of qt-*.
I've tried a number of suggestions, and I have unmerged and remerged
packages.

I am now trying to individually merge packages with dependencies on
qt-*-4.5.2.

I tried KDE 4.3.1, with some trepidation, and I have happily been running
gnome, save a couple of nits, and I have run into qt issues in the past.  I
would like to uninstall kde4 (like it, but not well enough to devote so many
resources to it, and to have to upgrade frequently and painfully).  I would
like to remove the KDE 4 installation, but keep the individual packages
depending on kdelibs.  (K3b, etc.).  Would this have an impact on this
issue?  This is off topic, but how to uninstall EXCEPT what I want, of
KDE4?   Is this reasonable?

Thanks.  I hope to solve this soon,  but it's too early to know whether the
help on this list was enough.  I changed USE flags, and the same messages
appear:

  Title                     Qt 4.5.2 default USE flag changes
  Author                    Alex Alexander <wired@gentoo.org>
  Posted                    2009-09-27
  Revision                  1

Qt version 4.5.2 has significant changes in the USE flags enabled by
default.

When upgrading, make sure you check and re-enable any USE flags you
need.

Depending on your system and installed packages, you might hit an issue
where Portage is getting confused by this USE flag change, trying to mix
old 4.5.1 ebuilds with new 4.5.2 ones, resulting in blocks.

If this happens to you, please add the offending USE flags (usually
'qt3support' and 'dbus') in your USE= or switch to a desktop profile
(eselect profile list). Check this post [0] for more details on this
issue.

I have this in my USE flags and I didn't run into this that I recall.

qt3  qt3support qt4

I think they are planning to remove qt3 in the future.  I'm not sure how
close that future is tho.  I think qt3support is the key here.

Other than the thread that Dale offers, have you changed your profile to the 
latest 10.0?  This had caught me out and went unmerging/emerging qt to get 
things to work.  I think it would have been easier if I had updated my 
make.profile first which has the required default USE flags:

$ ls -la /etc/make.profile 
lrwxrwxrwx 1 root root 54 Oct 22 10:03 /etc/make.profile -> 
../usr/portage/profiles/default/linux/x86/10.0/desktop

HTH.

With regards to this:
I believe I'm in the same situation:

<QUOTE>

These are the packages that would be merged, in reverse order:

!!! Multiple package instances within a single package slot have been pulled

You may want to change this to .../amd64/10.0/desktop or server depending on 
what your machine is.  Then I would think that the flags for qt3support would  
be enabled by default.  However, I am running x86 over here so others may be 
able to confirm.

Yes.  This is one of the issues I ran into.  Done.

I think that if default/linux/amd64/10.0 is a valid profile, it's 
reasonable to expect that the relevant news item be listed on eselect.

It takes 1 minute to change it and try emerge -upDv world before you change it 
back if you so prefer.

Have you tried doing what it says here, i.e., enabling
USE="qt3support" in, e.g., make.conf? (Sorry if you've already stated
that you have, I'm getting confused by the dozens of recent,
near-identical qt-problems emails.)

I think this problem has now gone away on my machine.  I cannot be sure what
it was that helped.  I removed all qt-* packages, and some of the
problematic packages mentioned as depending on the earlier versions.  After
running

     # emerge -utv world, I noted some dependencies, and may have removed
one or two.  Then I ran the install.

After a couple of interations, all *seems* to be well.

Thank you for the advice,

Alan Davis

I finally was able to emerge -NuDav world, and revdep-rebuild passed the
system as clean.  However, when I try emerge -uDav world again, that same
message, or some permutation of it, is presented.

I have set the flags "dbus qt3support qt3 qt4" and so on.  So that's not
it.

I unmerged a number of the involved packages, that looked something like
"qt-*".  I did this just before running the more or less successful "emerge
-NuDav world".  A week ago, I ran "emerge -e world".  Perhaps I need to do
this again.

I've read a plethora of postings, such as a sticky post on the Gentoo
Forums, and some of these emails, as well as googling, and tried several
things.

When this all began, about three weeks ago, or longer, I noticed problems
with

   hplip
   python

I have python 3.1 and python 2.6 installed,  Some advice was seen to make
sure eselect is pointing to 2.6.  I also ran python-updater.

A new work week is starting, my system is responding normally, I will avoid
KDE4, and type this all shakes itself out, over the next week or so.

Thank you to those who have helped.  Good luck to others.

Did you try the most straightforward (albeit lengthy) approach:

unmerge all of Qt
emerge world and let portage figure out what it wants to put back

There is seldom a good reason to have Qt packages in world (dev packages 
excepted) and recent changes in the ebuild have caused lots of mutual 
blockers. When I first went through this, I saw that almost all qt-* packages 
would be rebuilt on my machines. It seemed easier to restart with a clean 
slate. I got a blocker notice which said I had to enable various flags, which 
I did and the merge completed flawlessly.

I will try to uninstall all "qt-*"  packages.   I'd like to uninstall KDE4
also.

Simplest way I can think of:

eix qt-

Scroll up and down and note which ones are installed, there's only 20 in total 
and the colourized output makes it easy to spot the installed ones. Unmerge 
those.

That's what I did, then got back to the same message.  Even after unmerging

To see what's installed:
qlist -I qt-

To remove them:
emerge -Ca $(qlist -IC qt-)

We need to establish why qt-4.5.2 packages are being pulled in instead of 
4.5.3

Please run emerge -avuNDt world and post that (snipping irrelevant bits as 
appropriate).

You might have left a qt-*-4.5.2 package installed by mistake, or some other 
package is hard-coded to require a qt-4.5.2 version.

The solution for the first is to uninstall the package you missed, the 
solution for the second is to unmerge the offending package and remerge it 
(but recent portage should be taking care of that all by itself). Either way 
emerge -t will provide clues.

I forgot to mention:

After rebuilding all of qt with this amount of changes, be prepared to rebuild 
all of KDE-4 as well. Not doing this often results in weird behavviour that is 
impossible to track down, hence the large elog warning in all the qt-* 
ebuilds.
