Thanks for the report.

I encounter something similar in F24 with:
$ rpm -q dnf
dnf-1.1.9-2.fc24.noarch


output in terminal is:
Traceback (most recent call last):
  File "/usr/bin/dnf", line 58, in <module>

    d = _localeconv()
UnicodeDecodeError: 'locale' codec can't decode byte 0xe2 in position 0: Invalid or incomplete multibyte or wide character


steps to reproduce:
1. install Fedora 24 with 'Minimal Install' group
2. $ dnf install -y langpacks-de
3. $ reboot
4. $ dnf repolist # no error
5. $ LANG="C" LC_MONETARY="de_DE.UTF-8" dnf repolist # error


Additional info:
locale variables that seem to trigger the message are only:
LANG
LC_CTYPE
LC_MONETARY


complete locale I started out with:
LANG=C LC_CTYPE="C" LC_NUMERIC=de_DE.UTF-8 LC_TIME=de_DE.UTF-8 LC_COLLATE="C" LC_MONETARY=de_DE.UTF-8 LC_MESSAGES="C" LC_PAPER=de_DE.UTF-8 LC_NAME=de_DE.UTF-8 LC_ADDRESS=de_DE.UTF-8 LC_TELEPHONE=de_DE.UTF-8 LC_MEASUREMENT=de_DE.UTF-8 LC_IDENTIFICATION=de_DE.UTF-8 dnf repolist

Have you tried using dnf-2 instead of dnf? This seems to still work on my system.

for F24 x86_64:
$ sudo dnf install -y python2-dnf
$ LANG="C" LC_MONETARY="de_DE.UTF-8" dnf repolist # error
$ LANG="C" LC_MONETARY="de_DE.UTF-8" dnf-2 repolist # no error

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Works for me.
Should be fixed in dnf-1.1.9 (Take a look at this commit https://github.com/rpm-software-management/dnf/commit/93159e360f0b6150e598bba783e22ca113201a40)
In case reopen this bug and provide more info.
Thanks

The problem I describe in comment #6 and #8 is still present.

I cannot reopen this bug.
Shall I open a new bug?

Sorry for mislead. This bug should be fixed by commit mentioned above, but it is in next release. U can try it by enabling dnf nightly repository.

Btw, it has been fixed in rawhide.
