[gentoo-user] unclear (to me) errors from portage

[gottlieb]

I was away for two weeks and now one of my systems cannot be updated due
to  conflicts.  The entire (long) emerge output is at the end of
this msg.


------------------  The first conflict is -------------------


!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

dev-lang/perl:0

  (dev-lang/perl-5.16.3::gentoo, installed) pulled in by
    dev-lang/perl:0/5.16=[-build(-)] required by (net-analyzer/net-snmp-5.7.3_pre3::gentoo, installed)

  (dev-lang/perl-5.18.2-r1::gentoo, ebuild scheduled for merge) pulled in by
    =dev-lang/perl-5.18* required by (virtual/perl-File-Spec-3.400.0-r2::gentoo, installed)
    (and 1 more with the same problem)

----------------------------------------

I can't follow this.  For one thing net-snmp-5.7.3_pre3.ebuild does not
contain the string "lang" and I looked at all occurrences of "perl" in
the ebuild and don't see how dev-lang/perl-5.16.3 is required.

------------------  The second conflict is ------------

 * Error: The above package list contains packages which cannot be
 * installed at the same time on the same system.

  (media-video/ffmpeg-1.2.6-r1::gentoo, ebuild scheduled for merge) pulled in by
    >=media-video/ffmpeg-1.2.6-r1:0[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_ppc_32(-)?,abi_ppc_64(-)?,abi_s390_32(-)?,abi_s390_64(-)?] (>=media-video/ffmpeg-1.2.6-r1:0[abi_x86_64(-)]) required by (media-plugins/gst-plugins-ffmpeg-0.10.13_p201211-r2::gentoo, ebuild scheduled for merge)

  (media-video/libav-9.14::gentoo, installed) pulled in by
    >=media-video/libav-9.12[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_ppc_32(-)?,abi_ppc_64(-)?,abi_s390_32(-)?,abi_s390_64(-)?,X?,encode?,gsm?,jpeg2k?,mp3?,opus?,sdl?,speex?,theora?,threads?,truetype?,vaapi?,vdpau?,x264?] (>=media-video/libav-9.12[abi_x86_64(-),X,encode,mp3,sdl,truetype,x264]) required by (virtual/ffmpeg-9-r1::gentoo, installed)

---------------------------------------------------

I don't understand this since it looks to me that virtual/ffmpeg-9-r1
wants EITHER media-video/ffmpeg OR media-video/libav.  So if
gst-plugins-ffmpeg requires ffmpeg, why isn't virtual/ffmpeg satisfied,
i.e., why does it require that media-video/libav remain installed?

-------------- The entire emerge command and output follows
Note that I have
EMERGE_DEFAULT_OPTS="--ask --deep --tree --verbose --jobs --load-average=5"

e6510 ~ # emerge --update --changed-use --deep  @world

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

[blocks B      ] media-video/ffmpeg:0 ("media-video/ffmpeg:0" is blocking media-video/libav-9.14)

Total: 57 packages (28 upgrades, 1 downgrade, 8 new, 17 in new slots, 3 reinstalls), Size of downloads: 349,473 kB
Conflict: 1 block (1 unsatisfied)

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

dev-lang/perl:0

  (dev-lang/perl-5.16.3::gentoo, installed) pulled in by
    dev-lang/perl:0/5.16=[-build(-)] required by (net-analyzer/net-snmp-5.7.3_pre3::gentoo, installed)

  (dev-lang/perl-5.18.2-r1::gentoo, ebuild scheduled for merge) pulled in by
    =dev-lang/perl-5.18* required by (virtual/perl-File-Spec-3.400.0-r2::gentoo, installed)
    (and 1 more with the same problem)


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.

Have you tried this, last, suggestion? That is, have you tried to add
--backtrack=60 option to your usual update world command? For example,

emerge --update --deep --with-bdeps=y --newuse --backtrack=60 --ask world

I notice a few perl blockers.
You could try the following:

# emerge -vuD1 $(qlist -IC 'virtual/perl-*')
# perl-cleaner --all -v -- -v

And then retry to update world.
I've been encountering some perl blockages myself, and this cleared it up for 
me.

I also notice a conflict between

  media-video/ffmpeg-1.2.6-r1::gentoo, ebuild scheduled for merge

  media-video/libav-9.14::gentoo, installed

You may want to include which one you prefer (ffmpeg or libav) in your
call to emerge, and possibly include "--with-bdeps=y":

  `emerge -1uDNav --with-bdeps=y @world media-video/<selection>`

Note the addition of the '-1' or "--oneshot" option - you should always
use this when specifying libraries to emerge.

If I encounter an update of Perl like that, I always do it first and do
the perl-cleaner thing before anything else.  Otherwise portage will
crap out soon after the perl update is done because it seems to
automatically use the newer version before perl-cleaner is run.

On stable the most recent perl update seems very prone to blockers,
and I found that cleaning out the virtuals using the first command
given helped portage sort things out considerably.

If a package outputs an update notice like that, it is usually for a reason...

(Yes about --oneshot)

The choice of ffmpeg vs libav seems non-deterministic ??

I have a shell open directly on the machine e6510 and am ssh'ed
into e6510 from another machine

On the direct shell two successive runs of

e6510 ~ # emerge --update --changed-use --deep  @world
(I have EMERGE_DEFAULT_OPTS="--ask --deep --tree --verbose --jobs
--load-average=5")

gave different results.  The first one gave the error msg about libav
and ffmpeg conflicting; the second gave no error and is ready to go.  I
looked at the tree output and see that the successful one has an
uninstall of libav right before the install line for ffmpeg.  The
unsuccessful one does not have that line.

On the ssh shell, the first few tries gave the conflict error msg; but
then one succeeded (again proposing to uninstall libav).

Perhaps the dependency search uses multiple threads??

Since I must choose between libav and ffmpeg, I will use the choice that
portage (sometimes) makes and run the successful emerge command,
i.e. say yes to the question from --ask.

Is this nondeterminism documented or have I done something wrong.

Thanks for your help.

Thank you this fixed the perl blockers for me as well (but see my next

It's working as designed. The various deps for ffmpeg vs libav allow
either one to satisfy the dep, especially if you have virtual/ffmpeg in
world.

This new dynamic dep stuff allows portage a degree of freedom in
selecting such providers and sometimes it decides to use the one you
don't have. To satisfy that decision, it must then uninstall what you
have. I suspect the root cause of such apparently random behaviour is
that portage is loading your installed apps into an associative array,
and the order if items in those are random.

Two solutions::

1. use --backtrack <some big number>
   this tells portage to search deeper and hopefully realize you
   already have libav

2. Put libav in world, this will stop portage from trying to be helpful



I prefer the second choice as it makes things very explicit.

I kept ffmpeg, because I am used to it and because it seems to be more up to 
date than libav, plus it incorporates everything the libav fork has created 
since.  However, I am not sure if that is the recommended solution - at least 
in gentoo.  I'm not asking to start a flamewar between parent and fork 
advocates, but would like to check if I my understanding is wrong.

Views and experience on using either are welcomed.

This does surprise me.  Are entries hashed with a random value?

It looked as thought the successful choice is for portage to uninstall
libav so I am not sure inserting it into world would be helpful.  I
can't test it since the emerge has completed successfully (at least
without complaint).

I see.

On my other systems, no blockers have been reported.
Should I run the two commands above anyway?

I do understand "if it ain't broke, don't fix it", but I wonder if there
are problems waiting to happen that those two commands would eliminate.

Perl-cleaner and python-updater ensure the different perl and python dependent parts are rebuild against the configured perl and python packages.

Usually these are the latest versions.

Problems can occur when you run emerge --depclean and the perl or python versions used for said packages disappear.

I also would have concerns if different versions were used for different packages and they need to work together.

I always run perlcleaner and python updater after each update.

Hmm. I run them when perl or python has been updated. Have you found them to 
be needed at other times?

Incidentally, several months ago I said I would run python-updater before 
perl-cleaner because I thought it was more central to portage's operations.

No, but it's a script that runs daily on my build host.

It's Friday. Time of hope....

Anyway. We all have our own way of doing a regular update.

How often do you update? Daily or weekly?

Depends; if I have spare brain cycles and something is happening in the
tree that grabs my interest, then daily.

The one gentoo server I have left is often monthly.

Test vms get updated when I feel like it. Some of them never :-)

I tend to do it during the weekend or when I have a spare moment during the 
week.

The servers are done at least once a month.

They run locally in virtualbox on the laptop, and are fired up when

I try to avoid ubuntu. 
Tried it a few years ago. Looked ok, but didn't like the convoluted way to do a full update and ended up putting Gentoo on the netbook.

you mean

apt-get update && apt-get upgrade && apt-get dist-upgrade && apt-get
autoremove

?

Yeah, that drives me nuts too.

But it's better than Red Hat (dependency hell) and makes the office
staff workstations easy to admin (desktop stuff JustWorks for what they
need to do).

Plus, I refuse under any circumstances to run Gentoo on production
unless it's backed by a huge build farm or I have a large cluster that
are all identical and have very special needs.

Gentoo has it's uses cases, but a loose collection of servers none of
which are identical is not it.

or,

sudo do-release-upgrade

to upgrade from one LTS to the next?

The boss has banned upgrading from one LTS to the next:

- base system might upgrade OK but everything else atop it is risky
- last round of trying blew up in his face and stuff broke wholesale
- LTS are 2 (or 3?) years apart and the machines are usually due for
upgrade replacement on that cycle anyway
- this is a fast-changing devops environment when we usually rip the
whole lot out and do it over every 2 years anyway to deal with changes
in how the business is done and take advantage of new technology

Yes

emerge --sync
emerge -vauDN @world

This is how to update everything in 1 step. I don't like having to do a 
different command to update to newer versions. It's convoluted.

My solution with RPMs:
- Let the desktop try it
- Do a new install of latest version
(I use Centos on VMs for testing work related stuff)

I use Gentoo exclusively on the servers and desktops at home. I find it easier 
and more logical to maintain.
I do have a VM dedicated to building binary packages though.

It can be made to work, with some good planning.
But I agree that when the amount of servers starts getting quite large, some 
unification is necessary. But the same then is also true for any other OS.

I just got really tired of eternally being The Only One In The Place Who
Knows Gentoo(tm) and who doesn't blindly "emerge -uND world" on a remote
box then walk away....

At least with apt and yum juniors can be trained fairly quickly to do
reliable world updates safely. This keeps the boss off my neck. That
makes me happy.

On my personal servers and laptops, it will take on the order of atomic
warfare to make me give up my beloved Gentoo there :-)

People who do that should be taken outside behind the chemical shed and 
shot...

I've seen installations start acting really weird because sysadmins decided to 
update a redhat box the official way (yum).
Those usually ended up with backups being restored.

It doesn't matter which distribution you use, you still need to test updates 
on a seperate environment first to ensure all the software running on the 
environment will still work post-upgrade.

Hehe, same here.
