after having run emerge --sync && emerge --update --deep --newuse world , fixed the network interface configuration after reboot due to openrc changes, I run emerge --depclean As python-2.7 and python-3.1 were already installed, I was not afraid about python-2.6.6 removal but I was wrong. emerge was no more working after depclean The reason should be that /usr/bin/python2 was still a symlink to python2.6 and python2.6 was uninstalled. find /usr/{s,}bin -name "python*" -ls 652913 24 -rwxr-xr-x 1 root root 23712 May 8 20:23 /usr/sbin/python-updater 767051 0 lrwxrwxrwx 1 root root 9 May 28 13:30 /usr/bin/python2 -> python2.6 767107 0 lrwxrwxrwx 1 root root 14 May 8 20:19 /usr/bin/python -> python-wrapper 767045 0 lrwxrwxrwx 1 root root 9 May 8 20:19 /usr/bin/python3 -> python3.1 767363 4 -rwxr-xr-x 1 root root 217 May 8 20:19 /usr/bin/python-config 511277 8 -rwxr-xr-x 1 root root 5292 May 8 20:29 /usr/bin/python2.7 511326 4 -rwxr-xr-x 1 root root 1400 May 8 20:28 /usr/bin/python-config-2.7 703073 12 -rwxr-xr-x 1 root root 9388 Mar 28 12:56 /usr/bin/python-wrapper 214192 12 -rwxr-xr-x 1 root root 9388 May 8 20:19 /usr/bin/python3.1 215256 4 -rwxr-xr-x 1 root root 1177 May 8 20:19 /usr/bin/python-config-3.1 I made a few symlink try before finding the right fix, don't trust all symlink dates I fixed that temporary using ln -sf python3.1 /usr/bin/python After that, emerge was enought functional, so I could reinstall python2.6 and select again python2.6 as default Reproducible: Couldn't Reproduce Steps to Reproduce: I was not able to reproduce. I reinstalled python-2.6 with : emerge dev-lang/python:2.6 and selected again python2.6 as default with : eselect python set python2.6 I had a emerge --sync made, so maybe the issue was fixed between the 24 and the 28 may?

With information from this report, that's easy to unbreak emerge. But emerge was fully broken, so that could have being set at major level. It take me some days to understand and find a solution. This machine has been installed in 2005, so have survived to a lot of changes.
You probably forgot to run python-updater after updating python
I hadn't any special will to update python and I didn't ask a manual update of python before the breakage. emerge --update updated python for me, and I don't remember any warning that I need to run python-updater manually. The question I can't answer is why emerge --depclean had conclude python2.6.6 could be removed when it was still essential, at least for emerge itself.

You have to check that you don't need any of the packages: * Always study the list of packages to be cleaned for any obvious * mistakes All in all, it seems you didn't follow the instructions you were given. The messages are there to be read by you, not to be ignored by you.

I know for the warning in the ebuild. But even with the caution to repeat all warning messages at end of emerge, a warning may be out of screen when I come back to see the emerge result. This even happen with only 2 packages emerged. Try for example (with due care to python-2.7 removal) emerge --unmerge dev-lang/python:2.7 emerge dev-lang/python:2.7 subversion and you have to stay in front of the machine during the second emerge to see the python warning because 'Messages for package dev-vcs/subversion-1.6.16' use full screen size. Anyway, not running python-updater was for sure not the issue as I had python2.6 selected and working before the problem happen. > > > > > The question I can't answer is why emerge --depclean had conclude > > python2.6.6 could be removed when it was still essential, at least for > > emerge itself. > > emerge --depclean did its job as you asked it to do.

For me, that was far from obvious, knowing python2.7 and 3.1 installed, that python2.6 can't be removed. Probably the sentence could be enlighed for the way to check dependencies adding : using 'equery depends <package-name>' and eselect python --list I learn that the hard way, finding the python symlink mess /usr/bin/python2 -> python2.6 /usr/bin/python -> python-wrapper and run python-config to know that python2.6 is the default > All in all, it seems you didn't follow the instructions you were given. The > messages are there to be read by you, not to be ignored by you. I don't really subscribe to the point of view this is resolved but I appreciate the various help and the volontary work made on gentoo. I only could follow messages that I have seen with the knowledge I had at that time. Once you run emerge --update --deep --newuse world, you are instructed to run emerge --depclean. I do that and this once broke python and emerge. I understand that's hard to fix as I can't replicate. Even by emerging again 2.6, 2.7, 3.1, --depclean no more remove 2.6 (with python 2.6 or 2.7 selected as default). Using 'equery depends python', I understand no package require specifically 2.6. I am a bit unsure about the gory details about portage : sys-apps/portage-2.1.9.42 (!python2 & !python3 & !build? dev-lang/python:2.6) (!python2&!python3&!build? dev-lang/python:2.7) (!python2&!python3&build? dev-lang/python:2.6) (!python2&!python3&build? dev-lang/python:2.7) (python2&!python3? dev-lang/python:2.6) (python2&!python3? dev-lang/python:2.7) (python3? =dev-lang/python-3*) (!python2&!python3&!build? >=dev-lang/python-3) Why there is spaces on the first line to separate the conditions and not on next lines? I selected 2.7 and used emerge --unmerge dev-lang/python:2.6 and everything look to work.
Maybe "emerge --depclean" could be enhanced to skip python removal of version used by itself :-/
