[yocto] bitbake core-image-base -c do_populate_sdk fails with glibc (unmet dependencies)

[David Bensoussan]

Hello,

I tried to solve the issue by myself, read on the documentation and check
the mailing list, but I couldn't find the information I was looking for.
The documentation was of a great help as a guideline but I now don't know
how to proceed.

I wanted to generate an sdk and met these errors while executing:
$ bitbake core-image-base -c do_populate_sdk

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 packagegroup-core-standalone-sdk-target : Depends: glibc-gconv-cp1252 but
it is not installable
                                           Depends: glibc-gconv-ibm850 but
it is not installable
                                           Depends: glibc-gconv-iso8859-1
but it is not installable
                                           Depends: glibc-gconv-iso8859-15
but it is not installable
                                           Depends: glibc-localedata-i18n
but it is not installable
E: Unable to correct problems, you have held broken packages.

A long time ago, I generated one was using the adt-installer but it has
changed since.
I also tried to add in local.conf:
EXTRA_IMAGE_FEATURES = "tools-sdk"
DISTRO_FEATURES_LIBC = "libc-locales libc-locale-code"

But nothing worked. I am working with RPI3 machine under Jethro branch. My
first test was to try the same setup with qemuarm64 machine, it failed
exactly the same way. It seems there are conflicts in packages, but I don't
understand how to track the error at this point.

It raised multiple questions:
Am I doing it wrong? Did I miss a flag? What does this error exactly mean?

Thank you for your time

Regards,
