perl upgrade slot conflict

I'm trying to upgrade to perl 5.18. I get lots of slot conflict.

 emerge -pv --backtrack=30 perl

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

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

I tried few approaches but it didn't help. How can I solve this issue

Going by that list (though it would be good to know those "3 more"), you need to ad virtual/perl-Version-Requirements to the line.
Well, that is unless that virtual went away in 5.18.

It's installed. So how do I know what are the "3 more" ?

Every time I've run into this issue, it's required me to uninstall the things pulling in perl 5.16, then reinstall them afterwards (if I thought they were important/needed). My list has been considerably shorter, however.

Here is the output of the perl related packages that need to be updated.
In one of the outputs it was written that Pod-Simple Test-simple can break the system. Somehow related to perl 5.20. So I didn't try to emerge these packages. Someone knows anything about it?

So, which packages, I should emerge first? It's weird that I get so many slot conflicts and portage doesn't manage to solve it.
I usually emerge few packages at a time, and then try again to emerge perl. I already emerged in this way about 10 packages.

Your regex isn't quite specific enough.

Try

Code: Select all

eix -I perl-core/ | grep "^\[U\]"

Code: Select all

eix -I dev-perl/ | grep "^\[U\]"

Code: Select all

eix -I virtual-perl/ | grep "^\[U\]"

You are correct here. I missed that particular detail.

The difference in the regex is that yours greps anything with the character class "U". So you were getting packages that didn't actually need to be updated.

Ok. But what I need?

perl-core/Storable or virtual/perl-Storable ?

Both. Revisions of one (the virtuals) seem to be causing blocks of the related core.

Presuming you do not have perl packages in your world file,

Have you tried emerge -1auD $(qlist -IC 'virtual/perl-*') to update the virtual packages first and then re-tried perl-cleaner --all?

Both actually, assuming I'm understanding correctly. I have both installed on my system.

I think you're getting the blockage because virtual/perl-Storable (and other virtuals) is expecting perl 5.16 internally. As stated earlier, I usually resolve these conflicts by uninstalling the virtuals, update perl, then re-emerge the virtuals. Once you have perl 5.18 installed, you should get the virtuals associated with perl 5.18.

This might work too, and save you all the unmerging and remerging.

I didn't try it yet. I ran now the command you suggested with pretend flag to see what it will give me. It still throws slot conflicts. Probably, I will have to uninistall everything related to virtual.

Code: Select all

 emerge -1auDpv $(qlist -IC 'virtual/perl-*')

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

Now it throws that it can break the system. Why it throws about version 5.20 at all?

Do I need to uninstall all the installed and needed upgrades of virtual/perl or just those that are ? If it's both, then it's a list of 30 packages.

I get exactly your output when trying to emerge >5.18, since 5.20 is currently hardmasked. Do you have perl '**' keyworded somewhere? (e.g. grep -i perl -R /etc/portage/*)

Maybe heed developer advice and avoid 5.20 unless you want testing environment with breakage.

I don't want the testing version at all.

Thanks for the tip. I found a package that was keyworded. I disabled that line. Still it throws about version 5.20. In any case I won't allow version 5.20 to be installed. In any case, it doesn't even wants to install 5.20.It tries to pull 5.18. So on this side, I am safe

steveL · Post by **steveL** » Thu Aug 07, 2014 8:57 am

If you haven't upgraded perl yet, you need to add it to the list:

Code: Select all

emerge -1 -avDN '=dev-lang/perl-5.18*' $(qlist -IC 'virtual/perl-*') dev-perl/extutils-pkgconfig

as [post=7593126]discussed here[/post] (and next couple of posts. I'd forgotten we can use qlist -IC for this.)

You should be able to run perl-cleaner--reallyall after that, though you might want to do it after world, or split it (see man perl-cleaner.)

dev-perl/extutils-pkgconfig isn't a virtual, but is needed for building other perl modules. You don't want -u as in some cases it will be the same version of the package, and we still want it remerged to record newer deps in the vdb.

If you're still getting blocks for perl packages, add those to the list too; I'd like to know what those are if you do.

What I can do with blocks B which is unresolved conflict. Which ones should I remove? the perl-core/Module-CoreList or the virtual/perl-Module-CoreList etc?

The lower case "b" are blocks that portage can resolve itself.

These are the troublesome bits:

If it were me, I'd write down the list; uninstall them; upgrade perl; then reinstall. Then run perl-cleaner --reallyall.

If it were me, I'd write down the list; uninstall them; upgrade perl; then reinstall. Then run perl-cleaner --reallyall.

Which ones to uninstall? The packages of perl-core/... or the virtual/...? or both?

queen wrote:Which ones to uninstall? The packages of perl-core/... or the virtual/...? or both?

The perl-core ones less than a certain version; they are blocking the incoming virtuals, which are likely provided as part of perl itself.

However you have other things in there as well; it's interesting that you're getting more with eix, when using -u.
Personally I'd just get what I needed in, so do something along the lines of:

Code: Select all

emerge -av -1 --no-deps =dev-lang/perl-5.18* $(eix '-I#' 'virtual/perl-*') dev-perl/extutils-pkgconfig
perl-cleaner --reallyall --  -av
emerge -avuDN world --with-bdeps=y

You don't need to worry about EIX_LIMIT since it's being captured (so no tty.)

Not sure if you'd actually need to clean manually, but it might be required if perl-cleaner can't resolve; I'd hope it would cope. And as I said before, you might want to do world before main perl-cleaner, in which case do perl-cleaner --all before emerge world, and perl-cleaner --modules after to catch any which haven't been upgraded, before you depclean. Guess that might be better after depclean. As you can no doubt tell, we're just exploring this problem-domain.. ;)

We're looking to remove virtuals/pkgconfig (ie those in that list) which are installed but have been removed from tree. There might be other things we need to check, though like dev-perl/* and perl-core/*; and you can add those, though you'll need a separate eix call for each iirc. Be sure to 'quote' them so it's eix which is interpreting them, and not the shell.

Out of interest, what is the output of the qlist vs the eix commands above, on their own (latter with EIX_LIMIT if you're getting the 50+ message)? ie what list are we passing to emerge; I'd like to know if -u is adding extra packages, somehow.

Thanks, steveL, that did it for me!

Yay :D Glad to hear it mephinet, I'll code it in to update over next few days, so this is automatic in future.

VoidMage · Post by **VoidMage** » Thu Aug 14, 2014 4:08 pm

I went through this upgrade yesterday.

IIRC, on amd64 things went quite smoothly - I think I needed to add only one more package to the emerge line, subslots managed to pull the rest.
On x86 (where I needed to keyword a few things - arch team is lagging there), to make the first step, 'emerge -1pv dev-lang/perl `qlist -IC virtual/perl-`' sufficed, but I've got very few perl packages.

Hi Steve

Thanks a lot for the reply. Sorry for the delay, I was busy with other things. I ran the command

Code: Select all

emerge -av -1 --nodeps =dev-lang/perl-5.18* $(eix '-I#' 'virtual/perl-*') dev-perl/extutils-pkgconfig

and it went smoothly. Pay attention it should be --nodeps instead of --no-deps.

However when I ran

Code: Select all

 perl-cleaner --reallyall --  -av

it failed with blocks

Code: Select all

* perl-cleaner is stopping here:
 * Fix the problem and start perl-cleaner again.
 * 
 * If you encounter blockers involving virtuals and perl-core, here are
 * some things to try:
 *   Remove all perl-core packages from your world file
 *     emerge --deselect --ask $(qlist -IC 'perl-core/*')
 *   Update all the installed Perl virtuals
 *     emerge -uD1a $(qlist -IC 'virtual/perl-*')
 *   Afterwards re-run perl-cleaner

So, I followed the instructions and the deselect command worked well, but on the line of

Code: Select all

  emerge -uD1a $(qlist -IC 'virtual/perl-*')

it failed with blocks.

Code: Select all

emerge -uD1a $(qlist -IC 'virtual/perl-*')

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

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

OP, did you resolve your issue? I'm going suggest what worked fine for me on x86 and amd64 without knowing more details on your end.

Consider a current tree sync just to help eliminate any unknowns as I cannot recreate your issue.
On both I did a standard emerge -avuND @world which updated perl and later errored out elsewhere (another package) with the post messages (w.r.t. perl core package from world file removal and updating perl virtuals).
The next step following that suggestion was to ensure no perl-core packages were in your world file and to then update the perl virtuals. This should and seems to eliminate the blocker issues (for most of us).
Once prior step was successful then run perl-cleaner --reallyall.
Finally, if successful, resume emerge -avuND @world.
If that succeeded, then a emerge -ac after (aka depclean).
