 |
|
Hello all!
I'm looking for a little insight into this message I've received over the last few system updates:
| Code: | WARNING: One or more updates/rebuilds have been skipped due to a dependency conflict:
dev-python/more-itertools:0
(dev-python/more-itertools-8.3.0:0/0::gentoo, ebuild scheduled for merge) USE="-doc" ABI_X86="(64)" PYTHON_TARGETS="python3_7 (-pypy3) -python3_6 -python3_8 (-python3_9)" conflicts with
dev-python/more-itertools[python_targets_python2_7(-),python_targets_python3_7(-),-python_single_target_pypy3(-),-python_single_target_python2_7(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-),-python_single_target_python3_8(-)] required by (dev-python/zipp-1.0.0:0/0::gentoo, installed) USE="-doc -test" ABI_X86="(64)" PYTHON_TARGETS="python2_7 python3_7 (-pypy3) -python3_6 -python3_8"
|
I'm not sure if perhaps the text coloring will help to identify the problem:

primarily: what does the error mean?
secondarily: what should I do about it?
I originally thought it was something transient that would resolve after a few syncs, but it's been a couple of days now, and it persists; I'd rather figure it out & fix it before it becomes a blocker.
Any insights appreciated (: |

What is the exact emerge command you gave?
There is a reason because your dev-python/zipp is stuck on the 1.0.0 version?
The problem is that zipp-1.0.0 is compiled with python2_7 support but dev-python/more-itertools not have this support version.

hi fedeliallalinea!
thanks for replying.
basically, it's | Code: | | emerge --update --newuse --changed-use --deep --changed-deps --keep-going @world |
I don't have any special USE flags for zipp -- in fact, | Code: | | grep -ri python2_7 /etc/portage/* |
comes back empty, (so not set in package use flags or make.conf either), but does have PYTHON_TARGETS set to "python2_7 python3_7", so I guess that's coming from my profile (default/linux/amd64/17.1/desktop/plasma) ?
iow, I don't (as far as I can tell) have any explicit requirement for python2_7, but my profile lists it as a possible target; is that the problem? Is there something else I should be looking for? |

python2_7 target is set by default, with also python3_7, by profile.
The problem is understand because zipp is stuck in 1.0.0 version when the latest stable is 3.1.0, you can post equery d dev-python/zipp output?

Not the OP, but dev-python/importlib_metadata-1.6.1 seems to be the cause of the DEP.
| Code: | These are the packages that would be merged, in order:

yes, following the chain:
| Code: |
❯ equery d zipp
* These packages depend on zipp:
dev-python/importlib_metadata-1.6.1 (dev-python/zipp[python_targets_pypy3(-)?,python_targets_python2_7(-)?,python_targets_python3_6(-)?,python_targets_python3_7(-)?,python_targets_python3_8(-)?,-python_single_target_pypy3(-),-python_single_target_python2_7(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-),-python_single_target_python3_8(-)])

❯ equery d importlib_metadata
* These packages depend on importlib_metadata:

(python_targets_python3_6 ? dev-python/importlib_metadata[python_targets_pypy3(-)?,-python_single_target_pypy3(-),python_targets_python3_6(-)?,-python_single_target_python3_6(-),python_targets_python3_7(-)?,-python_single_target_python3_7(-)])
(python_targets_python3_7 ? dev-python/importlib_metadata[python_targets_pypy3(-)?,-python_single_target_pypy3(-),python_targets_python3_6(-)?,-python_single_target_python3_6(-),python_targets_python3_7(-)?,-python_single_target_python3_7(-)])
❯ equery d dev-python/markdown
* These packages depend on dev-python/markdown:

net-nntp/sabnzbd-3.0.0_rc1 (python_single_target_python3_6 ? dev-python/cheetah3[python_targets_python3_6(-)])

(python_single_target_python3_8 ? dev-python/cheetah3[python_targets_python3_8(-)])
|
it's ultimately sabnzbd which brings in this chain (and I know sab moved up to python 3 recently) -- I'm not sure how to resolve this though. It looks like python2_7 was dropped and now things are stuck:
| Code: |
❯ equery u more-itertools
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for dev-python/more-itertools-8.3.0:

globally
- - python_targets_python3_6 : Build with Python 3.6

ok, I could have sworn I tried this last night, but perhaps not:
| Code: |
emerge -1 more-itertools
|
rebuilds more-itertools and a system update no longer complains. I thought this was what I needed to do -- perhaps I was doing something else wrong last night -- I remember this being the solution for a similar issue in the past. Anyhoo, thanks for all the help people (: |

| o, nm, I'm mistaken -- a world update still complains with the same message ); back to square 1. |

If you can try to remove python_targets_python2_7 use flag to dev-python/zipp package with /etc/portage/package.use

yeah, I realise that py2.7 is supposed to be dead; I don't want to do a system-wide expunge for the packages that may still be using it and break; but perhaps fedeliallalinea has an idea in trying to convince just _one_ package not to use py2.7; when I'm back at my home machine, I'll try again.
Thanks again for all the help; I <3 the gentoo community  |

neither zipp nor more-itertools have python_targets_python2_7 as a USE flag:
| Code: |
❯ equery u zipp
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for dev-python/zipp-3.1.0:
U I
- - doc : Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of
globally
- - python_targets_python3_6 : Build with Python 3.6
+ + python_targets_python3_7 : Build with Python 3.7
- - python_targets_python3_8 : Build with Python 3.8
- - test : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test
but can be toggled independently)
❯ equery u more-itertools

+ + python_targets_python3_7 : Build with Python 3.7
- - python_targets_python3_8 : Build with Python 3.8
|
So I can't turn that off via USE flags. I thought I'd try a "big hammer":
| Code: |
❯ PYTHON_TARGETS=python3_7 emerge -1 more-itertools zipp
Calculating dependencies... done!
[ebuild U ] dev-python/more-itertools-8.3.0 [5.0.0]

but that (obviously) doesn't work :/ I know it's a warning for now, but my feeling is that if I can't resolve it, these kinds of things will just compound until I'm in a world of hurt ): |

You should disable python2_7 recursivly, now is dev-python/importlib_metadata package that need to disable this use flag.
As Josef.95 say you can disable python2_7 to all packages and enable it only for packages that forcibly require it.

Not zipp, just the packages that depend on it. In his case importlib_metadata.

Dr.Willy, thanks, that's the ticket -- explicitly setting
| Code: |
dev-python/importlib_metadata -python_targets_python2_7
|
resolves the issue (I should have noticed this in the last bit of the emerge output!); I'd rather let py27 fizzle out by itself instead of trying to be clever about masking it off everywhere and then needing to fix up anything depending on it.
I've also raised the issue here: https://bugs.gentoo.org/733146 in case the package maintainer cares to resolve it.
Thanks again for the help, everyone. |
