In F23, dnf defaults to dnf-3 and you have missing python3-dnf-langpacks package. Can you install it and then check "dnf langlist" ?

[root@new-host-5 leinfeva]# dnf langlist

Ok later i've edit /etc/dnf/plugins/langpacks.conf and uncomment 

#langpack_locales = ja, zh_CN, cs, pt_BR, mr


later i've run "dnf langinfo ja" and here is the output

[root@new-host-5 leinfeva]# dnf langinfo ja

Before this i have a little question. should be a require of dnf-langpacks the package python3-dnf-langpacks?

[root@new-host-5 leinfeva]# rpm -qR dnf-langpacks
/bin/sh
config(dnf-langpacks) = 0.14.0-1.fc23
dnf
dnf-langpacks-conf = 0.14.0-1.fc23
langtable-python
python(abi) = 2.7
python-dnf-plugins-core
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PartialHardlinkSets) <= 4.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(PayloadIsXz) <= 5.2-1

I just split dnf-langpacks into meta-package dnf-langpacks and sub-package python-dnf-langpacks. If you check 0.15.0 update then just installing dnf-langpacks will pull python3-dnf-langpacks.
