Gentoo – UnicodeEncodeError: ‘ascii’ codec can’t encode character ‘\xc4’ in position 83: ordinal not in range(128)

Recently emerging package =dev-lang/go-1.13.4 under Gentoo failed on one of our virtual servers with:

>>> Failed to install dev-lang/go-1.13.4, Log file:

>>>  '/var/tmp/portage/dev-lang/go-1.13.4/temp/build.log'

The above log shows that the emerge fails in the installation phase when moving the files to the proper path in the system. The problem there is a non-ASCII character in the file name or path, but the environment is set to use ASCII as language.

The solution is to check if the environment LANG is set and what it contains. In this case, we should set the LANG environment to utf8.

export LANG=en_US.UTF-8

Most of the cases this kind of error could occur with virtual servers, docker (or the other kind of containers like lxc, podman and so on) containers and chroot jails or screens with changed user with su or sudo! In our case, the LANG just got missed because of a switch user procedure in a container and the emerge failed with the above error. When the LANG is missing probably the default value is “C”. In fact, check not only LANG but also the “LC_ALL” environment variable (it may have different value, which is wrong!), which also should be “en_US.UTF-8”:

export LC_ALL=en_US.UTF-8

Or try removing it at all with

unset LC_ALL

Gentoo – updating perl and problems like perl-core/ is blocking virtual/perl-

When upgrading Perl under Gentoo it’s almost typical to have blocks of the kind:

[blocks B      ] <perl-core/File-Path-2.160.0 ("<perl-core/File-Path-2.160.0" is blocking virtual/perl-File-Path-2.160.0)
[blocks B      ] <perl-core/Module-CoreList-5.201.905.220 ("<perl-core/Module-CoreList-5.201.905.220" is blocking virtual/perl-Module-CoreList-5.201.905.220)
[blocks B      ] <perl-core/Archive-Tar-2.320.0 ("<perl-core/Archive-Tar-2.320.0" is blocking virtual/perl-Archive-Tar-2.320.0)

These blocks appeared when we tried updaring the Perl 5.26 to 5.30 (dev-lang/perl-5.30.0:0/5.30::gentoo from dev-lang/perl-5.26.2:0). This update is a major update.
So what does it mean?
The virtual package and the perl-core package should be the same version, but it appears there are no corresponding same versions to the virtual package versions (). The problem is that the update depends on a newer version of File-Path, Module-CoreList, and Archive-Tar but there are only virtual packages with the required versions. Virtual packages are just meta-packages and they do not install any module. First, what are the virtual/[perl-module] and perl-core/[perl-module]:

  • perl-core/[perl-module] – perl independent modules. In fact, the same module may be independent and it may be part of the build-in packages from the Perl main package – dev-lang/perl. Sometimes you may choose the independent package, because of a newer version than the version included in the dev-lang/perl package.
  • virtual/[perl-module] – perl meta-package, which ensures the installation of the module. The module could be an independent package from above or module, which is included in the main Perl package (in dev-lang/perl)

To solve the blocks of this kind “perl-core/ is blocking virtual/perl-” you must check for a newer version of perl-core/* if there is no newer version, just to remove the package and let the setup (emerge) use the module included in dev-lang/perl.

In our case, there are no newer versions of the three packages and we remove them with:

emerge -Cv perl-core/File-Path perl-core/Module-CoreList perl-core/Archive-Tar

And then emerge with no problems the new version of Perl with:

emerge --verbose --verbose-conflicts --backtrack=200000 $(qlist -IC|grep perl|sort|uniq) media-gfx/inkscape media-gfx/imagemagick dev-php/pecl-imagick

For detail explaination of why we use verbose-conflicts, backtrack, qlist and three excplicitly added packages you may read our article on similar subject – Gentoo updating perl with many masked and blocked packages

emerge – ERROR: 17.1 migration has not been performed – upgrade from 13 to 17.1

When upgrading to 17.1 profile you need to perform additional steps to get to a healthy Gentoo portage system using profile 17.1.
Here what we stumbled when we tried to upgrade from 13 to 17.1:

As you can see there is news, which consists of 12 steps to perform a successful upgrade to profile 17.1.
You can read the news with (the news output is included at the end of this article, just for completeness):

eselect news read 28

Specific note for our upgrade – in fact, our Gentoo installation was a chroot and it had not been updated for three years. The profile was 13.0 and portage supported only EAPI 5, which is a real problem. The new portage tree (we installed the latest) has no profile 13.0 and our emerge was half broken. We have preliminary steps described in Failed to install sys-apps/portage – Called pkg_preinst – portage._compat_upgrade.default_locations

Because we upgrade from 13.0 to 17.1, first, we need to perform the 17.0 upgrade (check the original steps here – https://gentoo.org/support/news-items/2017-11-30-new-17-profiles.html)

STEP 1) Select the previous profile 17.0 temporarily.

srv ~ # eselect profile set default/linux/amd64/17.0

You won’t be able to build any GNU GCC and you cannot continue with the next step.

STEP 2) Upgrade to GNU GCC 6.4.0 or later.

Our current GNU GCC is really old – 4.9.3. The latest version is gcc-9.2.0-r1 and we are going to use it.

Failed to install sys-apps/portage – Called pkg_preinst – portage._compat_upgrade.default_locations

Recently there was a problem with one compute node servers, which Gentoo (in fact, the chroot environment had not been updated for 3 years) could not emerge the new portage because it kept failing in the pkg_preinst with:

srv ~ # USE="-rsync-verify" emerge -va '=sys-apps/portage-2.3.76::gentoo'

>>> Failed to install sys-apps/portage-2.3.76, Log file:

Note this is the installation phase, where everything from the build process passes smoothly, but it fails to install it with some vague error of a dying line with a couple of python and portage environments. The problem is the current portage does not support EAPI 6 and 7 and some packages were unable to be installed!

And we fixed the issue by just using the method described in our previous article – Fix your broken or old portage in Gentoo, fix the emerge command
Cloning a new portage software and using it to emerge (install) a newer (or reinstall the current) portage in the system to fix the system’s portage and the emerge command:

cd /root
git clone https://anongit.gentoo.org/git/proj/portage.git
/root/portage/bin/emerge --sync
eselect profile set default/linux/amd64/17.1
/root/portage/bin/emerge -v portage

Now the latest and stable Gentoo profile is 17.1, so we set it to be sure we use it (in future this may change).

Fix your broken or old portage in Gentoo, fix the emerge command

Using Gentoo for servers and chroots it might happen to deal with old and not regularly updated Gentoo environment, which in some cases is completely non-updatable using the regular process with emerge command. And no emerge means no installs from the Gentoo packaging system. Or you maybe have a broken portage after failed update with missing emerge command or missing or broken portage modules

In general, this article is for those, who cannot update their “sys-apps/portage” or even the emerge command exits with errors and is of no use.

In cases such as:

  • Missing portage files (broken portage)
  • Broken emerge command (broken portage)
  • no update of new portage is possible – very very old portage, which does not support EAPI of all current “sys-apps/portage” (now is EAPI=5) and you do not have old portage ebuild files
  • Easy update the portage to the newest in an old Gentoo system.

A real world errors are included at the bottom for each case above.

You need just a working python 2.7.x and git to clone “https://anongit.gentoo.org/git/proj/portage.git” or at least some tool to download the portage package.

Our example is to repair a completely broken portage with error:

srv ~ # emerge -va portage
Traceback (most recent call last):
  File "/usr/lib/python-exec/python2.7/emerge", line 42, in <module>
    import portage
ImportError: No module named portage

STEP 1) Clone the portage package from the git or download the portage tarball.

If you do not have a git client you can always check the URL in the sys-app/portage ebuild and download the URL. Still, if you cannot find the tarball’s URL, you can just simply get a mirror such as https://mirror.leaseweb.com/gentoo/distfiles, wait for the loading of the page (12Mbytes, it’s huge, all Gentoo tarball files’ names are here) and grep in it by the name “portage”. Or you can check here https://dev.gentoo.org/~zmedico/portage/archives/. Download the latest tarball and unpack it in the /root directory.
Using git is the easiest method, but is the same with downloading and unpacking the tarball in the “/root”.

emerge – cannot sync with gpg: keyserver refresh failed: General error because of wrong date

Trying to sync one of our virtual servers we got a sync error not able to refresh the OpenPGP keys. The virtual server was just resumed and it was OK before the pause. In addition, there were no errors in dmesg or some kind of kernel panics. All seemed to be working even the server was in the distributed compiling node and no problems there. But still, the emerge syncing the portage tree wasn’t possible!
And the problem was the date of our virtual server, which was 4 months behind the real date!

Check the time and date of the server – if it is behind or in the future with a big interval this is the root of the problems with the inability to refresh the GPG keys.

Just synchronize the clock of the server and be careful when you resume pause virtual servers! When you resume them you should synchronize the clock because in multiple environments the clock might be wrong!
We have multiple articles on the time syncronization topic – openntpd – immediately sync the clock on startup, simple time synchronization of a server (laptop, desktop) using built-in systemd-timesyncd service and more.

Gentoo kde-frameworks/kdewebkit failed compilation with Qt5WebKit could not be found because dependency is required

Updating the KDE Plasma Desktop in our Gentoo workstations this time failed with

CMake Error at /usr/share/cmake/Modules/CMakeFindDependencyMacro.cmake:48 (find_package):
  Found package configuration file:

    /usr/lib64/cmake/Qt5WebKit/Qt5WebKitConfig.cmake

  but it set Qt5WebKit_FOUND to FALSE so package "Qt5WebKit" is considered to
  be NOT FOUND.  Reason given by package:

  Qt5WebKit could not be found because dependency is required to have exact
  version 5.11.x.

It was strange because the previous emerge included the QT upgrade from old 5.11.2 to 5.12.1 and this dependency should have been resolved properly before:

emerge -vau $(qlist -IC|grep dev-qt|sort|uniq)

But apparently despite that the emerge built all QT libraries in dependency order the “dev-qt/qtwebkit” was built against the old QT libraries. And this is what is saying the above error!

The solution is really simple just rebuild the dev-qt/qtwebkit

root@srv ~ # emerge -va dev-qt/qtwebkit

These are the packages that would be merged, in order:

portage is blocked by “the current version of portage supports EAPI ‘6’. You must upgrade”

We’ve synced the portage tree before upgrading our old portage package (big mistake! always upgrade the portage package before sync) and then do the sync. After the sync the portage upgrade was impossible, because a dependency package supported only a new portage API (probably a new package) in our case EAPI 7 and the offensive package was “app-eselect/eselect-pinentry“.
So there are two options:

  1. Find the last version of the portage,which does not depend on the package – app-eselect/eselect-pinentry
  2. Find if some of the USE flags disable the inclusion of this dependency – app-eselect/eselect-pinentry

We chose the second option and found that if we compiled the portage package with

-rsync-verify

the portage did not pull the dependency “app-eselect/eselect-pinentry” and then after a successful upgrade we had the portage supported EAPI 7 and reinstalled it with activated “-rsync-verify”.

Access Violation error when compiling packets in Gentoo – symlink

Here is another example of Access violation error when building packages in Gentoo. This time the build process could not make a symbolic link in “/usr/bin” and the build process of the package failed with:

 * ACCESS DENIED:  symlink:      /usr/bin/stransmit
CMake Error: failed to create symbolic link '/usr/bin/stransmit': permission denied

A detail explanation is available in our first article on the subject here – Access Violation error, when compiling packets in Gentoo.
All packages are built in a sandbox and there is a sandbox configuration in

/etc/sandbox.d/00default

, which instruct the build process where could write. If you get such error in 99.99% there is a bug in the package and if you do not want to wait for fixing it (report it!) you can manually edit the SANDBOX_WRITE variable and add the path, which causes the build failure. Build the package and remove the added path!!! Or you risk to make your system less secure!

>>> Failed to emerge net-libs/srt-1.3.1, Log file:

>>>  '/var/tmp/portage/net-libs/srt-1.3.1/temp/build.log'

In the installation phase occurred the package failure leaving half installed package. So we edited the “/etc/sandbox.d/00default” and added “:/usr/bin” at the end of SANDBOX_WRITE:

SANDBOX_WRITE="/usr/tmp/conftest:/usr/lib/conftest:/usr/lib32/conftest:/usr/lib64/conftest:/usr/tmp/cf:/usr/lib/cf:/usr/lib32/cf:/usr/lib64/cf:/usr/bin"

Then rebuild the package with emerge and remove the added path “:/usr/bin”. This is a dirty workaround, but it will allow you to use srt (and as a dependency to another packages’ installation).

Gentoo emerge: Failed Running automake

This article is for Gentoo build problem:

Failed Running automake

but basically the problem could occur in any Linux system and the solution is logically the same.

We have installed automake, the dependency is OK, there is no need of new version of automake (the libmemcached did not required to install a new version as a dependency), but still the build process failed!
automake has many different versions installed on the same system and the problem is that one of your currently installed version is too old, so you must upgrade all versions (from the all different branches installed).
First check what versions are installed (equery is part of app-portage/gentoolkit):

root@srv ~ # equery list automake
 * Searching for automake ...
[I--] [??] sys-devel/automake-1.11.3:1.11
[I--] [??] sys-devel/automake-1.12.6:1.12
[I--] [??] sys-devel/automake-1.13.4:1.13
[I--] [??] sys-devel/automake-1.14.1:1.14
[IP-] [  ] sys-devel/automake-1.15.1-r2:1.15
[IP-] [  ] sys-devel/automake-1.16.1-r1:1.16

We have version from branch 1.11, 1.12, 1.13 and 1.14 – one of these version is causing the problem!
Up until now no package required as a dependency 1.15 and 1.16, so we do not have it installed.

Here we upgrade them all to their latest versions in every branch version:

root@srv ~ # emerge -vu sys-devel/automake:1.11 sys-devel/automake:1.12 sys-devel/automake:1.13 sys-devel/automake:1.14

These are the packages that would be merged, in order:

Calculating dependencies... done!

Total: 4 packages (4 upgrades), Size of downloads: 5133 KiB

As you can see we have updated version in every branch! And after updating them the building of libmemcached passed smoothly!
It’s not only in Gentoo, in most Linux distros (such as Ubuntu, CentOS, Manjaro, Mint and so on) have multiple automake version installed, so if you encounter this problem check your automake version installed for their latest versions and also if you miss some of them.
