You should definitely try=
 this first if you haven't.

I have. 

If the package was go=

ve (unsuccessfully) made these attempts:

Is there any reason that =
you need to add py3.9 to all packages? If you
need it for something special, add it to those packages only, and let
portage take care of python targets for you instead of continuously
trying these big hammers. Ideally you should have *no* python targets
set manually in make.conf or USE files.

I added it because I saw python3_9 in the PYTHON_TARGETS list for, e.g. jinja, and hoped that it would force compatibility.=C2= =A0 That is the question of the original post.=C2=A0 But that was ju= st one of many attempts. 

The emerge command wa=
s:

sudo emerge --verbose=3Dy -vuUD   --verbose-conflicts   dev-python/setupto=
ols dev-python/setuptools_scm dev-python/certifi dev-python/markupsafe dev=
-python/jinja dev-libs/libxml2

Since it seems sphinx is =
installed with a different set of python
targets than what you're trying to update, you should include sphinx
in that emerge command to let it update to the same python targets and
solve the conflict.

Arve

I tried adding that but it didn't help.

Below is the latest build output, with no PYTHON_TARGET specifications.

I don't think this output or any list participant has actually identified where the problem here is.=C2=A0 In my origi= nal posting, the only difference causing the slot collision for jinja was that one had a PYTHON_TARGETS of 3-7 and the other of 3-8.=C2=A0 I asked how to force it to the correct value, but = if someone explained that to me, I didn't understand it.


I'm afraid I'm going to have to give up on gentoo, although I'm pretty heavily invested in it.=C2=A0 I'm spending too many hours trying to maintain my systems and running into too many seemingly arbitrary roadblocks.=C2=A0 I'm told I should update every week, but I can't get a system updated in a week.

So what do you really want to know?


Well, for starters, why emerge(1) is not emerging...



Using jinja with python3.6 3.7.3.8 3.9 at the same time?


I don't know what jinja is and I just switched over to python3 myself.=C2=A0 I'm not into subtleties like 6, 7, 8, or 9.

I do an emerge @world, it tells me I have slot collisions and stops.=C2=A0 Following Neil B.'s advice, I try to go through the collisions and see what the differences are.=C2=A0 jinja was a nice example, because there was a collision of the same package with itself!=C2=A0 The only difference was the PYTHON_TARGET.=C2=A0 I hop= ed someone could explain how I could force equivalency in that simple case.


Or want to keep it with 3.6 or some else?

The default PYTHON_TARGETS now change to 3_8 from 3_6. So when you update, many software need to change.


Yeah.=C2=A0 That surprises me, actually.


If you want to change that targets, just follow https://wiki.gentoo.org/wiki/Project:Pyth= on/PYTHON_TARGETS
Maybe there no different or compatibility=C2=A0 with it actually, bu= t we need a correct dependency.


I'm trying to emerge.=C2=A0 I'm not developing anything.



If you do not have enough time to update and config gentoo,
=C2=A0maybe you should try other Linux like Arch(No need to compile) and Debian(less update).


Yes, that's always an option.=C2=A0=C2=A0 On the other hand, it mig= ht be possible to improve gentoo so that not only the very brightest people can use it.=C2=A0 Source is kind of like a vaccine - if enoug= h people use it, it can help prevent the spread of viruses.
