World update conflicts due to removal of python 3.10

[snowman30]

Hi,

I just wanted to update my system via emerge -uDvpN world. Last world-update was several weeks/months ago.

I had python_targets and python_single_targets both set to python3_10.
This is not available anymore and now I can't seem to find any update route, as there are several conflicts, which seem to be all linked to the python3_10 issue.

What I now have is

• */* PYTHON_TARGETS: -* python3_12 python3_13
  */* PYTHON_SINGLE_TARGET: -* python3_12

But this still results in conflicts. How can I update my system?

[Banana]

Well, the result of your emerge command is helpful, so please provide. Also the exact emerge command you used and the output of emerge --info

A general advice about the PYTHON_TARGETS, use them only if really needed and only package specific and not globally.

[Hu]

If your last update was several months ago, why is the system still pinned on python3.10? The Gentoo standard switched to python3.11 on 2023-05-01, and then switched to python3.12 on 2024-06-01. You may need to go back in time and update to a newer python target using an older Portage tree. The exact output of the failure may tell us more.

Just for the sake a completeness, you could try

Code: Select all

*/* PYTHON_TARGETS: -* python3_11 python3_12
*/* PYTHON_SINGLE_TARGET: -* python3_11

to check if it raises same set of issues as with configuration reported in OP.

Thks 4 ur attention, interest & support.

Hi,

Thanks for your answers.
The emerge output was so lengthy, that I couldn't post it here, and even pastebin complained about the length.

So anyway, as suggested, I went back in time and checked out an older portage tree from end of April this year. Currently, I am compiling with

Code: Select all

*/* PYTHON_TARGETS: -* python3_10 python3_12 python3_13
*/* PYTHON_SINGLE_TARGET: -* python3_12

This seems to work so far, but will still take some time. Eventually, I will remove python3_10, if everything works out.

Will keep you posted.

[NeddySeagoon]

snowman30,

--depcean will remove orphan packages, including python(s).
It should be part of your update routine.

[snowman30]

Current status: I was able to finish a world update (there was a qtwebengine package ) with the old portage tree.

However, there are still a lot of dependency conflicts.

Code: Select all

*/* PYTHON_TARGETS: -* python3_12 python3_13
*/* PYTHON_SINGLE_TARGET: -* python3_12

Just to clarify, you were able to successfully update the system to the end of April?

Two months is not so much time, the update should go smoothly. It's not even two months. Perhaps you have world pollution. Post the contents of your /var/lib/portage/world file.

Also why did you set those python targets?

That python3_10 should not be there.

emerge -pvUdu --backtrack=0 @world
The output is a ~15MB file: https://limewire.com/d/xqetg#zLjFXWXXLF

[logrusx]

Go through the dev-python packages. If you can't recall why something is in world, deselect it. After that try updating again.

Also I don't think glibc should be in world either.

Also you should not need python targets set. Comment them.

I can't check the output right now.

Best Regards,
Georgi

[snowman30]

The python packages are in there because I need(ed) them.

When I comment out the python target sets, I need to set python 3.12 targets for several packages, as 3.13 is not yet available for them (e.g., platformio and freecad, and then, as a consequence, for several other python packages). But then again, I get the blocking dependency conflicts...

[logrusx]

Any "there are no ebuilds to satisfy..." in the output with --backtrack=0? Those might give a clue from where the problem comes.

EDIT: Just saw the output. I've given you the wrong command. It should have been capital D, lowercase is for debug, that's why the output is so huge:

Code: Select all

emerge -pvuDU --backtrack=0 @world

Regarding the commented python targets, keep them commented and add the entries requiring python 3.12 to package use. There's no point to compile everything for 3.12 just becasue a select number of packages. Keep the entries versioned (with = only, not >=) so that you don't forget about them. New versions will either support 3.13 or emerge will throw errors about them. This way you won't forget.

Try again and look for "there are no ebuilds to satisfy..."

Best Regards,
Georgi

[snowman30]

Thanks for looking into it.

Following your suggestion with the 3.12 packages (= only) and currently doing an "emerge -uDN world"

[logrusx]

You should have posted emerge output anyway. I migh have been able to spare you some more problems.

Best Regards,
Georgi

I'm a bit lost here, add --tree to the emerge command and let me see what it says. Also which entries did you add to package.use?

EDIT: actually did you run a depclean? That might solve some of your issues.

Best Regards,
Georgi

[snowman30]

Yes, I depclean'ed

emerge -pvuDU --backtrack=0 --tree @world

Code: Select all

These are the packages that would be merged, in reverse 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.

Would it hurt / make sense to unmerge dev-python/pip and dev-python/packaging?

[logrusx]

Well, it doesn't show what I hoped for.

But maybe if you drop the backtrack switch, it could work out a solution? I asked you to include it just because it would cause portage to give up as soon as it hits the first error. Try it and let me know how it goes.

p.s. check your package.accept_keywords for version fixed or obsolete entries.

Never use emerge --unmerge for a situation like this. You could try emerge --ask --depclean --verbose dev-python/packaging dev-python/pip, which will gracefully refuse to continue if these are needed. Targeted depclean can remove things that are held by an explicit world entry, whereas the general emerge --ask --depclean will not. Otherwise, keep following the advice from logrusx.

That first bit of output says setuptools-scm still has python3.10, and as long as it does, packaging needs python3.10 too - and packaging no longer offers python3.10, hence the conflict.

Hm.. interesting:

equery d dev-python/pip

Don't rely on 'equery d' to be smarter than portage because it isn't.
The command here shows what may depend and not actually depend. If portage is offering to depclean, then it is not used in your configuration (assuming you did not place it in the world file via direct emerge selection).
