Hi,
Got some more details on this...
Apparently, the errors are generated because of the use of Python 3.5.3
included in Yocto / PetaLinux.
The "Failed to set locale, defaulting to C" message seems to be logged from
dnf, i18n.py/setup_locale():
def setup_locale():
try:
dnf.pycomp.setlocale(locale.LC_ALL, '')
except locale.Error as e:
# default to C locale if we get a failure.
print('Failed to set locale, defaulting to C', file=sys.stderr)
os.environ['LC_ALL'] = 'C'
dnf.pycomp.setlocale(locale.LC_ALL, 'C')
(https://github.com/rpm-software-management/dnf/blob/master/dnf/i18n.py#L80)
The call that fails is dnf.pycomp.locale.setlocale(locale.LC_ALL, ''), which
calls locale.setlocale(locale.LC_ALL, '') under the hood.
During petalinux-build, I observed a couple of bitbake processes running with a
Python 3.5.3 included in Yocto. Ex:
21093
/media/bluetiger/Data/Xilinx/PetaLinux/components/yocto/source/aarch64/buildtools/sysroots/x86_64-petalinux-linux/usr/bin/python3.5
/media/bluetiger/Data/Xilinx/PetaLinux/components/yocto/source/aarch64/layers/core/bitbake/bin/bitbake-worker
decafbad
A quick tests shows that with the Python 3.5.3 included in the Yocto/PetaLinux
package the locale.setlocale(locale.LC_ALL, '') call fails, while the Python
3.6.6 installed on Ubuntu 18.04.1 LTS works as expected.
Python 3.5.3 included in Yocto (PetaLinux):

My initial idea was to comment out the print() command from the
i18n.py/setup_locale(), but I not sure where the file is located. Any idea
where the file is located?
An another solution would be to somehow force bitbake to use the Python 3.6.6
installed on the system.
Or do you have other suggestions on how to fix this?
Thanks,
Attila
