[gentoo-user] broken dependencies?¿

[Arnau Bria]

Hi, 

trying to purgue my system found next:

pataki ~ # emerge -p --depclean

*** WARNING ***  Depclean may break link level dependencies.  Thus, it is
*** WARNING ***  recommended to use a tool such as `revdep-rebuild` (from
*** WARNING ***  app-portage/gentoolkit) in order to detect such breakage.

*** WARNING ***  As a safety measure, depclean will not remove any packages
*** WARNING ***  unless *all* required dependencies have been resolved.  As a
*** WARNING ***  consequence, it is often necessary to run

Calculating dependencies... done!

Dependencies could not be completely resolved due to
the following required packages not being installed:

~sys-apps/suspend2-userui-0.6.4 required by sys-kernel/suspend2-sources-2.6.19-r3

Have you forgotten to run `emerge --update --newuse --deep world` prior to
depclean?  It may be necessary to manually uninstall packages that no longer
exist in the portage tree since it may not be possible to satisfy their
dependencies.  Also, be aware of the --with-bdeps option that is documented
in `man emerge`.

But I've already done so:

pataki ~ # emerge -uDpvt world

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

Calculating world dependencies \
!!! Ebuilds for the following packages are either all
!!! masked or don't exist:
mail-client/sylpheed-claws

... done!

Total: 0 packages, Size of downloads: 0 kB

(ok, I must change my package.keywords...

So, I run a revdep-rebuild:

pataki ~ # revdep-rebuild -p
Configuring search environment for revdep-rebuild

Checking reverse dependencies...

Packages containing binaries and libraries broken by a package update
will be emerged.

Collecting system binaries and libraries... done.
  (/root/.revdep-rebuild.1_files)

Collecting complete LD_LIBRARY_PATH... done.
  (/root/.revdep-rebuild.2_ldpath)

Checking dynamic linking consistency...
 done.
  (/root/.revdep-rebuild.3_rebuild)

Assigning files to ebuilds... Nothing to rebuild

Evaluating package order... done.
  (/root/.revdep-rebuild.5_order)

Dynamic linking on your system is consistent... All done. 

And my kernel is:
pataki ~ # uname -a
Linux pataki 2.6.22-suspend2 #1 PREEMPT Wed Aug 1 ...

and I have both packages in package.keywords

# grep suspend *
package.keywords:sys-kernel/suspend2-sources ~x86
package.keywords:sys-apps/suspend2-userui ~x86


So, if all seems ok, why depclean says that I have a broken dependency?

TIA,

So you have sys-kernel/suspend2-sources-2.6.19-r3 still installed, 
probably left over from some emerge in the past. It wants 
~sys-apps/suspend2-userui-0.6.4, probably because only that version 
worked with the kernel sources in the devs opinion. This kernel version 
and ui version is no longer in portage so they cannot be emerged

You are using 2.6.22-suspend2, with these DEPENDs:
RDEPEND="${RDEPEND}
                >=sys-apps/suspend2-userui-0.7.1
                >=sys-power/hibernate-script-1.95"

That userui is in portage, so all you need is:

emerge -C =sys-kernel/suspend2-sources-2.6.19-r3

and everything should resolve.

Well, it won't fix your sylpheed-claws which is also not in portage, but 
that's another matter :-)

Not sure why I do have a concrete verison of gentoo sources installed
blocking new one... (it's supposed that I have upgarded my sources,
isn't?)....
Could you explain so, please?

Now I have this:
# emerge -uD world
Calculating world dependencies... done!
>>> Auto-cleaning packages...

>>> No outdated packages were found on your system.
 * GNU info directory index is up-to-date.

and all works fine. Many thanks.

Yep, my poor laptop. A long time with no maintenance... :-)

Now I have my wonderful and "new" claws-mail installed!!!
# eix -c claws-mail
[I] mail-client/claws-mail (2.10.0@08/01/2007): Claws-Mail is an email client (and news reader) based on GTK+

Ok, 
so how my system determines which is the version it must use for
calculating dependencies?
Cause I did not have that source in /usr/src and I did have just my
current one... and emerge says:

Installed versions:  2.6.18(2.6.18)(02:42:26 PM 11/22/2006)(-build -symlink -ultra1)
                          2.6.19-r1(2.6.19-r1)(01:11:30 PM 01/11/2007)(-build -symlink -ultra1)
                          2.6.22(2.6.22)(03:14:16 AM 07/31/2007)(-build -symlink)

Why 2.6.19-r3 and not 2.6.28?¿
(gonna unmerge 2.6.18 and 2.6.22!!)

In fact, as it's my laptop and I have no much space, I only keep
current kernel source (for modules buid)...
But thanks for the tip.

Thanks,
Arnau

Kernel sources are slotted, so each time you install a new version, the
old one remains. Like this

% equery list gentoo-sources
[ Searching for package 'gentoo-sources' in all categories among: ]
 * installed packages
[I--] [ ~] sys-kernel/gentoo-sources-2.6.21-r3 (2.6.21-r3)
[I--] [ ~] sys-kernel/gentoo-sources-2.6.22-r1 (2.6.22-r1)
[I--] [ ~] sys-kernel/gentoo-sources-2.6.22-r2 (2.6.22-r2)

You can unmerge the unwanted ones, but you'll also have to remove the
directories from /usr/src. In fact, it is faster if you remove the
directories before unmerging.

It uses all of them, because all installed packages need their
dependencies.

It looks like you deleted the source directory without letting portage
know what you'd done.

In that case "emerge --prune --ask gentoo-sources" will do what you
need, but you still need to remove the directories from /usr/src manually
because emerge only removes the files it installed, not any that were
created or modified by you, like when you compiled the kernel.
