ncurses has recently been upgraded to 6.0 and a new slot was created for compatibility with old applications however, the net-misc/dropbox-3.6.8 ebuild won't accept the slotted :5 ncurses ebuild ( sys-libs/ncurses-6.0 ) and wants to downgrade to ncurses-5.9-r101 Reproducible: Always Steps to Reproduce: 1. emerge ncurses 2. emerge dropbox 3. Actual Results: dropbox requires ncurses to be downgraded again to 5.9-r101 Expected Results: dropbox actually builds correctly with ncurses-6.0-r1 and the ebuild should allow for this version of ncurses
I saw this issue on one of my systems after updating from portage-2.2.20.1 to 2.2.21, but can't reproduce it any more after installing some kde packages. Perhaps this is a portage-2.2.21 regression. If you can reproduce this, please attach your "emerge --info" and the output of "emerge --pretend --debug dropbox" (if "emerge dropbox" is the command causing the error).
It's likely related to bug 558856. You might need to rebuild dropbox in order to get the latest deps: RDEPEND="|| ( sys-libs/ncurses:5/5 sys-libs/ncurses:0/5 )"
(In reply to Zac Medico from comment #2) The system where I was seeing the error had a freshly installed dropbox (re-emerged today). Portage attempted to downgrade ncurses (and printed a warning about it) when doing --update --deep @world, and then started behaving normally after I manually updated some kde ebuilds :/
This command will show all installed ncurses dependencies: grep sys-libs/ncurses /var/db/pkg/*/*/*DEPEND

Portage version installed 2.2.20.1 Upgrading to portage 2.2.22 does not fix this
(In reply to Michele Alzetta from comment #0) > Actual Results: > dropbox requires ncurses to be downgraded again to 5.9-r101 This behavior is correct, because dropbox is not compatible with ncurses-6, and currently it is not possible to install ncurses-5 and ncurses-6 simultaneously. The arrangement of ncurses slots is confusing because of bug 558856. Slot 5 only exists as a workaround for bug 558856, so slot 0 is the only "real" slot. Therefore, you have to choose between ncurses-5 or ncurses-6. > Expected Results: > dropbox actually builds correctly with ncurses-6.0-r1 and the ebuild should > allow for this version of ncurses The dropbox ebuild installs pre-built proprietary binaries that are distributed by dropbox.com, so you can't build it against ncurses-6.
So, anyone who has this problem should simply mask ncurses-6 as follows: echo '>=sys-libs/ncurses-6' >> /etc/portage/package.mask
Actually I solved the problem in the opposite manner i.e. I masked ncurses < 6 then hacked the dropbox ebuild by removing the dependency on a specific slot of ncurses, rebuilt the manifest and emerged dropbox. With ncurses-6.0-r1 dropbox emerges without problems on my box and has been working normally ever since ncurses was updated to 6 (I decided to file the bug later on) Only that each time I want to emerge world I have to uninstall dropbox, emerge everything, then repeat the hack and emerge dropbox again. Of course, I'm no expert on ebuilds and on ncurses so this is my very personal hack, it might bite me one day and I definitely wouldn't suggest anyone else use it, unless the experts decide something of the sort is ok.

You have to choose one version of ncurses *headers*, but ncurses-5 and 6 *libraries* can be installed in parallel. You can install, on the same system, =ncurses-6.0-r1 (from slot 0) for all normal ncurses-using things, and =ncurses-5.9-r101 (from slot 5) for the few closed-source packages like dropbox that require old ncurses libraries. I do this on all my systems. The ncurses slotting scheme is very similar to media-libs/libpng, media-libs/tiff, and media-libs/jpeg. Slot 0 is the main slot (headers and libraries), numbered slots are library-only for compatibility with old closed-source stuff. The only confusing aspect of ncurses slotting is =ncurses-6.0 which somehow ended up in slot 5 thanks to bug #558856.
Created attachment 413010 [details] /var/db/pkg/net-misc/dropbox-3.6.8/NEEDED.ELF.2
So, if I understand the situation, the best thing is to install both: a) ncurses-6.0-r1 (slot 0, which has headers and libraries) for all the rest of my system, and b) ncurses-5.9-r101 for compatibility with dropbox only Simplest way to do this is just mask ncurses-6.0 in slot 5 From the NEEDED.ELF file it definitely seems that dropbox requires ncurses 5, although I still have to find any glitch in functioning

I wonder if dropbox includes any command-line programs that might load this library somehow?
err... ok. I've read all comments, but i'm not sure of what i should do now. Right now i just can't emerge dropbox anymore ..?? How can i do ?
for unknown reasons dropbox ebuilds above version 3.6.8 .have ncurses-5.9-r101 dropped. Test case: get latest tarball (64bit in my case), unpack. oleg2 tmp # scanelf -qyRF "%F: %n" .dropbox-dist/ | sort | grep ncurses .dropbox-dist/dropbox-lnx.x86_64-3.17.31/_curses.so: libncurses.so.5,libpthread.so.0,libc.so.6 oleg2 tmp # But ebuild has no this stub ebuild dependency. In case box updated to ncurses-6 and then emerge --dpeclean ran, you have a system where drobpox will not run. Instlling ncurses-5.9-r101, which will install only libs sufficient fro dropbox and will not contaminate, because only consumer of this lib would be dropbox.
proposal to add ncurses dep back.
I added back the dep that was in 3.6.8 commit cf7a901f98941a46dc98a92751adea2225428ea0 Author: Jason Zaman <perfinion@gentoo.org> Date: Mon Apr 11 00:38:50 2016 net-misc/dropbox: version bump and add back ncurses 5 dep Package-Manager: portage-2.2.26
