Created attachment 455386 [details] screenshot unable to update by doing #emerge -avutDN world immediately. this issue got resolved by following steps: #emerge --unmerge ncurses #emerge @preserved-rebuild #emerge -avutDN world
Please post `emerge --info` so that we know your portage version. Have you tried it with --backtrack=30 as suggested in the emerge message? If a larger --backtrack values does not help, then the symptom is similar to bug 595224, but the underlying problem is that emerge fails to trigger a rebuild for some reason. If --backtrack=30 doesn't help, and you can still reproduce the problem, then please attach a snapshot of your portage configuration created as follows: tar -cJf /tmp/config.tar.xz -C / ./etc/portage --exclude CONTENTS --exclude '*.ebuild' --exclude environment.bz2 --exclude 'NEEDED*' ./var/db/pkg $(cd / && echo ./var/lib/portage/world*)
I'm posting the conflict message here for reference: !!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict: sys-libs/ncurses:0 (sys-libs/ncurses-6.0-r1:0/6::gentoo, ebuild scheduled for merge) pulled in by (no parents that aren't satisfied by other packages in this slot) (sys-libs/ncurses-5.9-r5-5:0/5::gentoo, ebuild scheduled for merge) pulled in by sys-libs/ncurses:0/5= required by (dev-util/cmake-3.5.2-r1:0/0::gentoo, installed) ^^^^^

executing # tar -xf /tmp/config.tar>test, is there no output.
As a side note, I have just suffered from this issue when trying to update a really old setup. It was also failing with --backtrack=10000. But, in my case, it was solved simply because there were two blockers: one was this ncurses one, the other was a conflict between net-analyzer/arping and net-misc/iputils[arping]. I simply unmerged net-analyzer/arping and, re-running emerge with --backtrack=10000, emerge was able to handle all the conflicts and it is now updating :) Then, maybe this issue is faced when another block is around leading to a misleading message suggesting the fault is on ncurses side, even if it can be solved once the other blocker is manually handled before
For any nonsensical conflicts involving built slot operator deps, you should use --ignore-built-slot-operator-deps=y as suggested here: https://wiki.gentoo.org/wiki/Project:Portage/FAQ#What_should_I_do_when_emerge_reports_a_lot_of_dependency_conflicts_involving_built_slot-operator_.28foo.2Fbar:X.2FY.3D.29_dependencies.3F I always use --ask, so that it will prompt me for autounmask configuration changes. For world updates, I always use --ignore-built-slot-operator-deps=y until I have made all necessary configuration changes. Only after I have made all necessary configuration changes (includes changes necessary to solve blockers), and the dependency calculation succeeds, I remove --ignore-built-slot-operator-deps=y from the command line. Also see bug 598503.
