 Posted: Mon Apr 18, 2016 7:39 pm Post subject: Can't install python 3.5, blocked packages |
 |
|
I'm trying to install python 3.5 so I can compile the latest version of blender (2.77a), which needs this as the minimum python version. Unfortunately, it appears the required python-exec version is being blocked... I think
edit: turns out the output is too much for one forum post, I guess. The point is that I don't know how to solve this problem, since I find emerge's "blocked package" output to never be helpful in finding the source of the problem. Any advice would be appreciated!
| Code: | $ sudo emerge -avu --backtrack=30 python

well just reading what it says directly on the blockers, you need python-2.7.10-r4 or newer for python-exec-2.4.3 (in this case, since there is no -r4, you need 2.7.11-r2)
Same thing for 3.3 and 3.4; just read what it's saying if < a specific version is blocking, then you need that version it is saying or newer...
In this case, it lies down to you mixing stable and unstable branches (which usually causes troubles)
Note: When you update python :2.7,3.3,3.4 you are going to have the usual issues of everything needs to be recompiled to the new version of python...
My recommendation, is update python-2.7,3.3 and 3.4 first to fix the original blocker and deal with all that hassle, then install python-3.5 and recompile the supported 3.5 python packages to support that
Note 2: Be aware, the python3_5 USE flag is MASKED, so you will have to unmask the USE flag, before packages will use 3.5 |

lue ... I suspect (though haven't verified) that you need the highest package in each of those slots, so 2.7.11-r2 (for the 2.7 slot), 3.3.5-r7 (for the 3.3 slot) and 3.4.3-r7 (for the 3.4 slot). Less than these and =dev-lang/python-exec-2.4.3 (required for the 3.5 slot) is blocked.
Try the following:
| /etc/portage/package.accept_keywords: | =dev-lang/python-2.7.11-r2
=dev-lang/python-3.3.5-r7
=dev-lang/python-3.4.3-r7 |

I'll try upgrading all the other versions of python I've got installed (and maybe uninstall at least one of the python3 slots if I can). I didn't realize the version numbers are newer than what I have installed.
In this case, by the way, I would've preferred to have portage list the upgrades but also require them to be keyworded, like it tends to do if I try to install an unstable package with unstable deps. In general, it'd be nice if portage could describe the steps to take, instead of the cryptic "blocks B" lines (when the solution isn't just updating things) and those unhelpful "pulled in by" sections printed below. In this case those "blocks B" are helpful enough (I just wasn't reading closely enough), I'm just used to them being unhelpful I guess. I imagine that would be a difficult thing to program, though.
Anyway, I'll go upgrade all my pythons, and that should do the trick. It does feel like I should stop mixing trees and just finally go to unstable  . |

lue ... I'd test the above accept_keywords to see if this in fact resolves the block before actually updating.

I'm not sure I like that feature at all ... basically it provides those who probably shouldn't with a green light to follow the suggested resolution (which is always away from stable and into testing) ... and this leads to "~arch is the new stable" (or worse, a blurring of the distinction).

I'm not sure portage should be providing something like 'advice', but the opacity of information isn't helping anyone, agreed.

That is the gravitational force implicit in the current schema, nobody (particularly not developers) are using 'stable' and so inevitably stable becomes something of a backwater, and so everything gravitates toward ~arch, increasing its mass (and so on ... in a vicious circle).

I can confirm that upgrading all versions of python to 2.7.11-r2, 3.4.3-r7 and 3.5.1-r2 solved this block for me.
However, blender 2.77a is now out, so I am now upgrading with the ebuild from https://bugs.gentoo.org/show_bug.cgi?id=536078#c42 |

Can anyone help me with this? It has occured on my latest update, which calls for all 3 updates and
will not accept masking. I'm totally baffled/
