After switching to kits, the new issue, when actually using biber to compile BibTeX formatted references, is: ERROR - Error loading data source package 'Biber::Input::file::biber': Can't locate Biber/Input/file/biber.pm in @INC (you may need to install the Biber::Input::file::biber module) (@INC contains: /etc/perl /usr/local/lib64/perl5/5.24.0/x86_64-linux-thread-multi /usr/local/lib64/perl5/5.24.0 /usr/lib64/perl5/vendor_perl/5.24.0/x86_64-linux-thread-multi /usr/lib64/perl5/vendor_perl/5.24.0 /usr/lib64/perl5/5.24.0/x86_64-linux-thread-multi /usr/lib64/perl5/5.24.0 .) at (eval 126) line 2. I ran `perl-cleaner --all` already.

Dear Oleg, thank for this commentary. The essence, I see, is to understand what and how to do. As you put it "when you know what to do with stable or unstable - you could expect things to work. if you don't know what to do, likely you'll trap into troubles regardless stable or unstable used." This is something that comes in time.

With the on-going change, it's expected that we, users, have several and different, difficulties. And while it is impossible to deal with all at once, I feel that one sticky thread should be there to guide. Or use only github's issues feature. Myself, have posted in various threads during the last weeks. And contribute, this way, in more noise. Apologies for that. Can we have one sticky thread for the Switch? Thank you

I followed (again) steps at https://github.com/funtoo/meta-repo#using-meta-repo and https://github.com/funtoo/meta-repo#updating-meta-repo.

However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically.

I am sorry I cannot actively contribute on this. I am ready to test if required.

Dear Oleg & Funtoo-Forum-ers, any news in fixing this?

Ping! From the discussion I cannot extract whether testing the meta-repo is safe enough and, successively, if reverting the changes is easy if it does not play out nicely yet.

I chose "stable" for my main working machine to have less updates to deal with. Then again, I did need to update some stuff to latest versions. And this brings some extra-maintenance work with it. I am happy to learn about "kits". Question: how do we migrate to current? Complete re-installation?

I am trying to get biber installed via a local ebuild, where I changed a bit the dependencies. But, it's a large circle of interdependencies. And the wrong way to deal with it. I need to get this done, to continue my work. Is there really no solution to clean up my environment? Can I not downgrade to all Perl 5.22 and, even, remove anything that needs Perl 5.24? I would sacrifice for the moment any other tool and more to get things working in LaTeX. I use i3wm, so I don't depend on KDE (which I do use some times). Thanks for any recommendations.

Maybe I can edit directly the ebuild, then?

However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically.

And, now after cleaning Perl related material, the opposite! Upgrade to the latest Perl version. emerge -av biber --verbose-conflicts These are the packages that would be merged, in order: Calculating dependencies... done!

However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook.

Meanwhile, I am re-doing `perl-cleaner --all`. Will re-post if something changes.

Yes, I use stable. And, indeed, at the same time, I have recent versions of various stuff installed. By the way, like others, me too, I am a (prime) candidate for kits (http://www.funtoo.org/News:New_Ports-2017_tree_and_Kits). Here the output, after (re-)moving `package.accept_keywords` from being present for portage: emerge -pvt dev-tex/biber These are the packages that would be merged, in reverse order: Calculating dependencies... done!

However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically.

However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. It is asked to downgrade to `perl=5.22.2`. Why?

possible to solve this problem by using package.mask to prevent one of those packages from being selected. However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically.

How can I cleanly reinstall KDE? I tried removing the mix-in and remove/clean but I did not succeed. Is there a standard process to follow? Like remove everything and keep the essential to have a running system, then reinstall whatever wanted? Without loosing configuration files, of course. Or is it better to try to resolve conflicts, one-by-one? But, it appears that they are too many.

How do we report this?

Here the result https://github.com/NikosAlexandris/osgeo-overlay, which would not exist without @hencb's help. There are still issues with the gdal-2.1.3.ebuild (see https://github.com/NikosAlexandris/osgeo-overlay/issues), but it was an overall good learning session.

I want to create newer e-builds for GDAL (see https://svn.osgeo.org/gdal/branches/2.1/gdal) GRASS GIS (see https://svn.osgeo.org/grass/grass/branches/releasebranch_7_2) To start, I have followed the steps outlined at <http://www.funtoo.org/Local_Overlay>. I created a local overlay named osgeo and went through the rest of the steps. What are the next steps? In example, what is the first thing to do in the "new" ebuild which is still a copy of the latest older existing ebuild, after having ran ebuild gdal-2.1.3.ebuild manifest Note, running ebuild *.ebuild manifest as suggested in the Wiki, I get !!! doebuild: 'gdal-2.1.3.ebuild' is not one of the following valid commands: !!! clean cleanrm compile config configure depend !!! digest fetch fetchall help info install !!! manifest merge nofetch package postinst postrm !!! preinst prepare prerm pretend qmerge rpm !!! setup test unmerge unpack Trying to emerge the "local" ebuild, comes with a WARNING not doing so: *** emerging by path is broken and may not always work!!! These are the packages that would be merged, in order: Calculating dependencies \ *** You are emerging a masked package. It is MUCH better to use *** /etc/portage/package.* to accomplish this. See portage(5) man *** page for details. >>> Waiting 10 seconds before starting... >>> (Control-C to abort)... Continuing... in: 10 9 8... done! For example, I navigate in /var/overlay/local/sci-libs/gdal where there are -rw-r--r-- 1 root root 758 Mar 11 13:47 Manifest drwxr-xr-x 2 root root 2 Mar 11 13:53 files -rw-r--r-- 1 root root 7439 Mar 11 13:43 gdal-2.0.3.ebuild -rw-r--r-- 1 root root 7439 Mar 11 13:45 gdal-2.1.3.ebuild What's on here? -- Similar I have done for grass.

Will search for answers elsewhere as it is more of a Kernel + ZFS issue, rather than a Funtoo issue. [content deleted]

Just closing this topic. All works fine.

Hi nimbius. Eh, I don't see the answer in my question. Installing Funtoo in a ZFS setup is ok -- following the installation guide. Please revisit my question if you care. Thanks.

Old topic, still valid. Now that the ZFS installation guide has been refreshed, and works, is it still too complicated to add a LUKS section in it? Would you encourage to do so? Or not? More interesting: is it possible and if yes, is there any reason not to: backup an existing ZFS pool wipe the target disk to erase traces of old data create a LUKS encrypted container map the LUKS container (and optionally, wipe it!) setup ZFS and "restore" the pool from the backup ? Note, it seems that native encryption for ZoL is a work in progress and should be soon available (?). See also: https://forums.anandtech.com/threads/gentoo-funtoo-zfs-luks-and-initramfs.2451033/.
