 Posted: Fri May 25, 2018 1:24 am Post subject: Python 3.6 per eselect news update |
 |
|
Hi,
I got my updates yesterday, saw the news item 2018-05-22 Python 3.6 to become the default target and went about following the instructions, or at least I thought I did.
I got to about the middle of the message and things broke.
I put in /etc/portage/make.conf,
| Code: | PYTHON_TARGETS="python2_7 python3_5 python3_6"
PYTHON_SINGLE_TARGET="python3_5"
...
USE="... python_single_target_pypy ..."
|
And now, when I get updates with emerge -aDNu --with-bdeps=y @world I get this:
| Code: | These are the packages that would be merged, in order:
Calculating dependencies... done!
!!! The ebuild selected to satisfy ">=app-text/asciidoc-8.6.0" has unmet requirements.
- app-text/asciidoc-8.6.10::gentoo USE="-examples -graphviz -highlight -test" PYTHON_SINGLE_TARGET="(-pypy) -python2_7" PYTHON_TARGETS="python2_7 (-pypy)"
The following REQUIRED_USE flag constraints are unsatisfied:
exactly-one-of ( python_single_target_pypy python_single_target_python2_7 )
The above constraints are a subset of the following complete expression:
exactly-one-of ( python_single_target_pypy python_single_target_python2_7 ) python_single_target_pypy? ( python_targets_pypy ) python_single_target_python2_7? ( python_targets_python2_7 )
(dependency required by "sys-fs/btrfs-progs-4.10.2::gentoo" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])
|
Not sure what I did wrong. Could somebody please point out the problem? |

It says what you need to do, in this case you need to add python_single_target_python2_7 to your package.use... |

| I added python_single_target_pypy to my make.conf USE declaration, I thought that would do it. |

| If a use flag is in ()'s, it means it is masked/forced and can not be used until you unmask that USE flag. |

And for unmask use /etc/portage/profile/package.use.mask

I reverted to my old make.conf and the system works.
Not really fixed since I'm still on my old python. I hope my system doesn't break whenever this upgrade goes down.
Thanks. |

1clue,
I will expound further beyond ct85711's reply. There are a few packages like asciidoc that will never support python3. Sadly asciidoctor is looking like it'll be the only solution. These packages are dependent on being individually listed in package.use as python_single_target_python2_7. I imagine it'll be automatic in the profiles by the time of the switch though.
so add this to package.use:
| Code: | | app-text/asciidoc python_single_target_python2_7 |
