Why does my system want ~amd64 ncurses? [SOLVED?]

Doing my daily update I ran into this:

Same here. I went over to bugs.gentoo.org to see if there was any new issues with ncurses. There's a couple of issues from this morning, not quite related to this problem, but there's a pungent smell of developer goofup here:

Same here.

I found that emerge was also reporting the same wrong change, which still blocked. I needed to add:

=sys-libs/ncurses-6.0

to my package.accept_keywords to allow the update to proceed.

I looked around, but couldn't figure out who was pulling in ncurses-6.

I ran into the same thing this morning. I'm pretty sure this is a mistake in the portage tree. My advice would be to skip your daily update for today and wait until this is resolved. I've seen this kind of thing in the past. Usually they get resolved pretty quickly (thank you Gentoo devs!)

Try again tomorrow. There's a good chance it may be resolved by then.

This is typically what happens when the developers make a base-level change on their keyworded systems and don't check it out first on a stable system before plugging the change into the tree.

On the bright side, if you have time to spare, you can go with the change and get a preview of what future breakage, if any, is coming your way when stable is fixed and bumped to support the change.

Same issue here. I wanted to update my system today, so I did this:

The_Great_Sephiroth · Posted: Wed Aug 26, 2015 7:15 pm Post subject: Testing ncurses required today?

I just did a sync and then tried updating the system set. For some reason, it wants to pull in the unstable version of ncurses. I cannot figure out why. Can somebody help me out here?

See https://forums.gentoo.org/viewtopic-t-1027536.html for a temporary workaround.

I've read the bug report and looked at the revised ebuilds for packages now slotted for (0). These soft-block any sys-libs/ncurses ebuilds at or below 5.9-r4 so they won't continue (mis)using the old slot, (5). The new ebuild for what is now the libcurses library-only slot (5) has been pegged by fiat at version 5.9-r100, a gentoo version level much higher than r4 and far above the limit imposed by the soft block, or so it seems to me. So it perplexes me, then, why ncurses-6:0, whose ebuild soft-blocks ncurses packages at or below 5.9-r4, should block the slot (5) library-only package pegged at 5.9-r100. Regardless of the combination of fingers and toes I engage for counting, I always seem to get r100 > r4. Perhaps I have not quite yet mastered the interplay among prefix operators, atom versions, gentoo revision numbers, slot and subslot numbers and packages soft-masked for testing. There is a non-Euclidean geometry at work in there somewhere.
For those of us managing boxes pretty conservatively -- not, as a rule, accepting any unstable packages -- it seems that the actual source of emerge's upset is that the soft blocking rules do indeed preclude the only current stable package, sys-libs/ncurses-5.9-r3, for all the other ebuilds are marked unstable across the architectures. So why not a message from emerge of the sort: "There are currently no ebuilds available to satisfy your requirements"? I don't quite follow its choice of error message. There is indeed blocking going on, but it is (should be?) ncurses-5.9-r3 or so it seems to me, and not ncurses-5.9-r100, which appears to have been deliberately versioned so high as to get past the gate imposed by the other ebuilds in their RDEPEND rule settings.
As a practical matter, short term, jagdpanther's suggestion to just exclude ncurses got me though the day (thank you!), and, one hopes, one of the other ncurses ebuilds will stabilize soon and then the whole matter will moot itself. This has been one of the more interesting world updates.

FYI

With a sync this AM, new ebuilds have come into addressing #558856: slot move of sys-devel/ncurses from 5 to 0 did not adjust vdb *DEPEND for ncurses atoms w/ subslot deps.

No unusual blocks are occurring; no requirement to accept unstable packages in the offing - this on a wholly stable box where soft-masked packages are not allowed. The condition which the OP observed yesterday, and seen here as well, is not recurring. It is a --quiet-build. Hopefully, others who hit this wall yesterday will have a better time of it on the next update.

Today's sync seems to have fixed it for me as well (by upgrading in 5.9-r5 and pulling in a slotted 5.9-r99 it seems)...

What should I do? Looks like should be fine, but is not:
