This update has turned into a nightmare.

-t option does not solve conflicts, it shows the dependency tree, helping you to find out why a package is pulled in.
emaint does not know what you want in world file, it only checks if all entries are valid packages.
You, and only you can decide what you want to be installed. It is a nobrainer, really. Everything you do not know needs to be removed from world file. For instance, gimp is OK, but glibc does not belong there (although this one is harmless because it is part of the system).

I cannot see that the -t argument adds any more useful information either. I may resolve zlib and libxcb, it is ridiculous how many times I have rebuilt long-runners such as llvm and mesa by now.

I'm not sure whether I should mask the special snowflake flake8 or accept that an older version of pyflakes should be installed onto the system.

I don't understand why it complains that there are no ebuilds to satisfy ">=dev-ruby/rubygems-2.5.1[ruby_targets_ruby23]" when there evidently is dev-ruby/rubygems-2.6.14 >= 2.5.1 available for emerge.

You have RUBY_TARGETS="ruby22" in your emerge --info. More freedom you give to the portage less conflicts you get.

thurnax,

The whole thing says ">=dev-ruby/rubygems-2.5.1[ruby_targets_ruby23]"
Portage needs dev-ruby/rubygems-2.5.1 or newer, with USE=ruby_targets_ruby23 and you only allow ruby_targets_ruby22.

Do not set RUBY_TARGETS yourself. It will be inherited from your profile.
If you do set it yourself, you need to maintain it yourself too.

Yesterday I had a problem with a world emerge. Portage said that (I forget which package) "package-5.4.0 is blocking package-5.4.0" and suggested unmasking a later version. The current version was latest stable and there was no use flag change. So I did "emerge =packageclass/package-name-5.4.0 --nodeps" which is a sharp knife but prevents portage from checking dependencies.
After that emerge "emerge -auvND world" showed no more action was required.

Portage is trying to be smart and handhold, but winds up like Westworld where nothing can go wrong go wrong go wrong...
I would rather that it state the problem inm human terms and forget about suggesting a solution.

I'm sure, had you posted the message here, we would have been able to read it for you.

I have a problem with ruby it appears. I have uninstalled everything related to ruby. If I 'emerge -s ruby' every package listed there is marked as "Not Installed". I added ruby back to the make.conf USE flags and I added changed the RUBY_TARGETS string to "ruby21 ruby22 ruby23 ruby24". I did 'emerge --changed-use' but still I cannot get the ruby packages to install. I tried to emerge the the individual packages using the --nodep argument that has a dependency with rubygems:

Portage database is created as the packages are installed, containing information about USE flags in use, etc. If it is lost then technically emerge -e @world should restore it, assuming all other configuration files are intact, but it seems a hard way to do it.

Look, I'm not trying to repair /var/db/pkg, I restored it as described in prior post, no harm done, I had a backup from before I started the update. The only thing that may be broken is the collateral damage from the command 'rm -rf /usr/lib64/python3.4/site-packages/". I did what I could to restore it but there may still be some package that is broken that I have not yet discovered. The details of my restoration procedure is described in prior posts.

I have managed to resolve the flake8 package by 'emerge --ask --nodeps flake8' so that one is out of the picture. I emerged ncurses with nodeps too and then oneshotted all 20 packages that depends on ncurses-5.9. All of the packages rebuilt successfully but one; lame. Reason: 'autoconf -I . --force' generated the following error:

Start by removing this line from your make.conf:

In prior post I indicated that I changed it to "ruby21 ruby22 ruby23 ruby24". I have now removed the line completely. It had no effect on emerge. Same errors persist.

I emerged gtk+ with version number explicitly mentioned; "=x11-libs/gtk+-2.24.31-r1" so with 'equery y', I have the following install configuration:

I don't have rubgems installed ... emerge -pv rubygems returns

Follow on question. Do you know why you need ruby? The ruby USE flag is set in your make.conf.

thurnax wrote he had to keyword some packages. This means something is broken already, building a mixed system is a recipe for conflicts.

It would be nice to be able to learn and develop ruby on rails applications on this system, but not an absolute necessity. I would prefer to use ruby 2.4 and rails 5 should I install it on this system. Earlier versions could work but most tutorials are geared towards these versions of ruby and rails. It is not a necessity though, as I understand, ruby is poorly maintained under Gentoo, or at least has been and I have another machine with Ubuntu, which probably is the best/safest distro for ruby on rails deployment, if I am to believe what people are saying about it.

When I did 'emerge --nodep dev-lang/ruby, it installed ruby-2.4.2. Then I also tried emerging back all the removed ruby packages, using --nodep. Most of them failed but some succeeded. I now have a ruby 2.4 module, i.e:

The problem with ruby seems to be that I'm unable to properly uninstall it, I don't even know how to do it. Merely removing the "ruby" useflag, or all use flags with "ruby" in them and then 'emerge --changed-use @world' doesn't help. I tried removing some packages such as "dev-lang/ruby" but the problem with rubygems as described above remains.

I tried manually editing "/etc/portage/package.accept_keywords" and removing every line that has "ruby" in it. That got rid of the error with rubygems, but now emerge is nagging me to add these USE changes:

While I generally appreciate brevity, it's often better when posting errors to post the entire output, starting from the shell prompt, showing the command you ran, all the output it produced, and up to (but optionally excluding the text of) the next shell prompt. Put all that in a single code block, no paraphrasing, and no trimming (except to split overly long lines). Similarly, if you run some commands, post their output, change system state, then run more commands, please indicate where in the flow of the post the system state changed. It's not clear to me whether your section beginning "But now that the message" is from the same state as the earlier part of the post or if you changed state to resolve the other errors and now have a new issue.

For the ncurses+bzip2 issues at the bottom of your most recent post: the ncurses issue requires rebuilding packages which depend on ncurses to handle the new subslot. The bzip2 issue requires filing negative feedback with Soap for a pointless bzip2 subslot change, then either hacking the subslot or rebuilding the packages that depend on it. (This latter change has caused numerous posts over the last few weeks, all from people who were needlessly forced to rebuild a package despite no actual compatibility issues. The only ones who didn't rebuild were the ones who used one of a few hacks to convince Portage that the change is a non-issue.)
