I have two systems that are close in both hardware and software.
Today I did eix-sync on each followed by
emerge --update --changed-use --with-bdeps=y @world
On one system (dell 6430) I was presented with many packages to merge
python-3.5.4 [ebuild NS]
many to reinstall [ebuild R]
This was not surprising.
The other system (dell 7450) failed with the following
!!! Problem resolving dependencies for sys-process/systemd-cron from @selected
... done!
!!! The ebuild selected to satisfy "sys-process/systemd-cron" has unmet
requirements.
- sys-process/systemd-cron-1.5.4::gentoo USE="-cron-boot -etc-crontab-systemd
-minutely -setgid -test -yearly" ABI_X86="(64)" PYTHON_SINGLE_TARGET="python3_4
python3_5 (-pypy3) (-python3_6)" PYTHON_TARGETS="python3_5 (-pypy3) -python3_4
(-python3_6)"
The following REQUIRED_USE flag constraints are unsatisfied:
exactly-one-of ( python_single_target_pypy3 python_single_target_python3_4
python_single_target_python3_5 python_single_target_python3_6 )
python_single_target_python3_4? ( python_targets_python3_4 )
The above constraints are a subset of the following complete expression:
exactly-one-of ( python_single_target_pypy3 python_single_target_python3_4
python_single_target_python3_5 python_single_target_python3_6 )
python_single_target_pypy3? ( python_targets_pypy3 )
python_single_target_python3_4? ( python_targets_python3_4 )
python_single_target_python3_5? ( python_targets_python3_5 )
python_single_target_python3_6? ( python_targets_python3_6 )
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])
Both 6430 and 7450 have the following content in
/etc/portage/package.use/systemd-cron
# systemd-cron needs PYTHON_SINGLE_TARGET = 3.x.
sys-process/systemd-cron python_single_target_python3_4
Those files are 2+ years old on each system
I have not let the 6430 proceed with the emerge update world.
Thanks in advance for any help.
