[gentoo-user] Daily update fails

[gentoo-user] Daily update fails

[Dan Johansson]

Today when I tried to do my daily "emerge --update ... @world", portage 
spitted out a lot of "Multiple package instances within a single package 
slot have been pulled" messages.

I thought this could be due to the depreciation of python3_6 so I added
*/* PYTHON_TARGETS: python3_6 python3_7
*/* PYTHON_SINGLE_TARGET: -* python3_6
,as per the news item published, to my package.use and now I get the 
following instead:

!!! The ebuild selected to satisfy "app-office/scribus" has unmet 
requirements.
- app-office/scribus-1.5.5-r1::gentoo USE="boost minimal pdf templates 
-debug -examples -graphicsmagick -hunspell -osg -scripts -tk" 
ABI_X86="(64)" PYTHON_SINGLE_TARGET="-python2_7"
python_single_target_python2_7
   The following REQUIRED_USE flag constraints are unsatisfied:
     python_single_target_python2_7

   The above constraints are a subset of the following complete expression:
     exactly-one-of ( python_single_target_python2_7 ) tk? ( scripts )

I tried to unmerge scribus but that just made another package complain 
about "python_single_target_python2_7".

Any suggestions on how to proceed?

You have globally masked python_single_target_python2_7 in package.use,
so now you need to unmask it for individual packages, starting with
scribus. It's a bit of a game of whack-a-mole, add a package, emerge
world, get another failure, add that package, rinse and repeat.

I'd suggest putting all these changes in a separate file in package.use
so it is easy(er) to track and undo these, hopefully, temporary, changed.

I had no issues with the changeover on systems running purely testing,
those running stable with a few testing packages required some attention.
If you are running such a system, you may find it easier to temporarily
unmask testing versions of some packages rather than play around with USE
flags.

So THIS would have been the issue you should have given us to solve.
Instead you borked your package.use by globally deactivating py2.7
and asked us to point you to that.

So please: Revert the python changes you did in your package.use,
rerun your update command and post the error you get with that.
Please post the whole output, including the exact command you used.
And also add "--tree --verbose" to the emerge options, this usually
requires less guessing.

Thx
Franz

Neil's suggestion made me add "PYTHON_SINGLE_TARGET: python2_7" to seven 
packages and now my box is happily compiling (will take some time as 
there are some "big" packages in there, i.e. firefox, chromium, ...).

As per your suggestion I will remove
*/* PYTHON_TARGETS: python3_6 python3_7
*/* PYTHON_SINGLE_TARGET: -* python3_6
and my "PYTHON_SINGLE_TARGET: python2_7" when finished and retry my emerge.

If it fails I can certainly post the Output here.

A short update:
Following the suggestion in the news-item I added
  */* PYTHON_TARGETS: python3_6 python3_7
  */* PYTHON_SINGLE_TARGET: -* python3_6
  and "PYTHON_SINGLE_TARGET: python2_7" for selected packages
to my use flags and run the update without issues.

After that "initial" update was done, I removed the added entries 
(including the "PYTHON_SINGLE_TARGET: python2_7" ones) and started a new 
emerge update. With exception of one package (net-misc/s3cmd) everything 
went as it should.

Thanks Niel for the hint about PYTHON_SINGLE_TARGET for the 
"misbehaving" packages.

Regards,

s3cmd has an older version in the tree, 2.0.2. 2.1.0 has python 3.7/8
support but no ebuild yet. There is a bug filed on this.

Always proofread carefully to see if you any words out.
