# emerge --info

I spend more time maintaining a language I don't actually use
lately...

Emerge fails becuase python-exec-2.2 doesn't have its expected
Pytnon version. Catch is that it appears that the current
version is 2.4, which seems to be installed:

dev-lang/python-exec
Latest version available: 2.4.8
Latest version installed: 2.4.8

This showed up when I added a new use flag "fuse" and
tried to run emerge:

emerge --update --ask --changed-use @world;

<snip>

emerge: there are no ebuilds built with USE flags to satisfy ">=dev-lang/python-exec-2:2/2=[python_targets_python3_6]".
!!! One of the following packages is required to complete your request:
- dev-lang/python-exec-2.4.8::gentoo (Missing IUSE: python_targets_python3_6) (dependency required by "sys-devel/clang-9.0.1::gentoo" [installed]) (dependency required by "@selected" [set])
(dependency required by "@world" [argument])

My current package.use files include:

*/* PYTHON_TARGETS: python3_8 python3_9 python3_10
#*/* PYTHON_SINGLE_TARGET: python3_10

Previously I had to have the single target in place to update one
of the packages, removing the PYTHON_TARGETS LINE leaves me with:

# emerge --update --ask --newuse @world;

<snip>

!!! Problem resolving dependencies for dev-python/backports-zoneinfo from @selected
... done!

!!! The ebuild selected to satisfy "dev-python/backports-zoneinfo" has unmet requirements.
- dev-python/backports-zoneinfo-0.2.1-r2::gentoo USE="-test" ABI_X86="(64)" PYTHON_TARGETS="(-pypy3) -python3_8"

The following REQUIRED_USE flag constraints are unsatisfied:
any-of ( python_targets_pypy3 python_targets_python3_8 )


I thought I'd seen news to the effect that the system was
standardizing on 3.8 at least, let alone 3.6.

Q: What is a reasonable range of Python versions to specify for a
current running system?

Q: Is there any combination of use flags, make settings, or
rain dances that will leave the system in an updatable state
going forward?

Thanks

Why do you have clang 9 installed? It is no longer in the repo, and
apparently requires a python-exec compiled against python 3.6. Unless
you have a particular need for it, the solution seems to be to remove
clang 9.

For your first problem, do what it says, create a line for the
python-exec which has python_3_6, and your other problem the package
wants 3.8 and that should fix you right up.

These are all python packages... is there no way to just sync
the python version and be done with it?

Have you done a depclean regularly? This package,
dev-python/ipaddress, has appeared in at least half of all threads
where someone is having upgrade trouble with these python errors. This
package left the repo a long time ago, and simply does not exist any
more, and hence can also be depcleaned.

emerge --depclean --pretend to see if you have a long list of packages
that portage could remove.

Arve
