Bug 573624 – dev-python/pip-8.x downgraded to dev-python/pip-7.1.2 due to unsatisfied dependencies

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

Since a few days when I try to update my ~ARCH system I got a message about skipped packages due to deps between dev-python/setuptools and dev-python/virtual-env. This message wasn't blocking emerge. Today this changed into

> !!! Multiple package instances within a single package slot have been pulled

> dev-python/setuptools:0

I manually removed dev-python/setuptools, dev-python/virtualenv and dev-python/pip and manually installed dev-python/setuptools-19.2, dev-python/virtualenv-14.0.1 and dev-python/pip-8.0.2-r1 which was possible however running 

# emerge --ask --verbose --update --deep --with-bdeps=y --newrepo --keep-going=y --newuse world

brings back the error.

When I add backtracking (--backtrack=30) I get

> !!! The following update(s) have been skipped due to unsatisfied dependencies
> !!! triggered by backtracking:
> 
> dev-python/pip:0

and emerge wants to downgrade dev-python/pip-8.0.2-r1 to dev-python/pip-7.1.2.

That's why I am reporting this against dev-python/pip.

Yep.

I have pip 7.1.2, setuptools 19.2, and virtualenv 13.1.2-r1 installed, and updates are broken due to the slot conflict.  A simultaneous -1 update of all three packages also fails.

pip-8 doesn't work with >setuptools-1.9.2.

[Comment 3 Grant Goodyear 2016-02-09 22:02:29 UTC]

Updates seem to work again, with setuptools simply not being updated past 19.2.  That's much better than the update breaking entirely.  Thanks!

old pip is old (and removed)
