[gentoo-user] Apparently 2.4 is not >= 2.2?

[gentoo-user] Apparently 2.4 is not >= 2.2?

[Steven Lembark]

Before I spend a lot of time backtracking all of this...

Q: Are either of these issues well-known pathologies of emerge?
 
Recently built a new Gentoo system by creating a new LV, extracting
stage3-amd64-openrc-20211205T170532Z.tar.xz and going through the 
handbook stages to get a running sytem.

I then installed a variety of packages I have on the current system
like fonts, claws-mail.

Catch is that I cannot update the sytem:

# $emerge --update --fetchonly @world;
Calculating dependencies... done!

The following packages are causing rebuilds:

  (x11-base/xorg-server-1.20.14:0/1.20.14::gentoo, ebuild scheduled for merge) causes rebuilds for:
    (x11-drivers/xf86-input-synaptics-1.9.1:0/0::gentoo, ebuild scheduled for merge)
    (x11-drivers/xf86-input-evdev-2.10.6:0/0::gentoo, ebuild scheduled for merge)

emerge: there are no ebuilds to satisfy ">=dev-lang/python-exec-2:2/2=[python_targets_python2_7(-),python_targets_python3_6(-),-python_single_target_pypy(-),-python_single_target_pypy3(-),-python_single_target_python2_7(-),-python_single_target_python3_5(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-)]".
(dependency required by "dev-python/pytest-runner-4.2::gentoo" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])


It seems that I have a recent enough python-exec installed: 2.4 >= 2.2.

# emerge --search dev-lang/python-exec

I'm having a similar issue with firefox-bin:

But I also seem to have a recent markupsafe, if 2.0.1 >= 0.9.2??

I may well be wront, but it looks like the problems are not due to 
version, but to python-target mismatches.  You may need to rebuild some 
stuff first, such as pytest-runner and mako.

Post the output of:

emerge --info dev-lang/python-exec

Python target troubles are indeed common around major python version
upgrades, which we've had quite a few of lately.

In your case, I would try running a depclean, dev-python/pytest-runner
does not seem to be in the tree at all, so complaining about not
finding a newer version satisfying the wanted python targets makes
sense there. Removing outdated packages is almost always helpful in
these instances.

You are probably right: I've spent more time playing with 
PYTHON*TARGET variables and succesive rebuilds on this machine
than actually doing any work for about a year. Annoyance is 
that I don't do anything else with Python here so it's only 
for the package manager. 

This is for a fresh build from a recent stage3. It shouldn't 
be this painful to just start a new system.

With a new system, I would think you should not need to alter the  
profile defaults in any way.  Once you do anything manually to those  
python variables, it likely devolves into a black hole.

I would find any python-target related variables in any portage config  
files, and seriously consider removing them.

As someone recently suggested in a different thread, start with just  
"emerge @system" then "emerge @world" (without any non-default options)  
and only when that is done, start adding back the --newuse and --deep  
options.

The other replies have also been good - in terms of where to start  
looking.  Also - which versions of python do you have installed, and  
which do you actually need?
