Lutris does not start in ubuntu 18.04

userpc@userpc:~$ lutris
Traceback (most recent call last):
File “/usr/bin/lutris”, line 29, in
locale.setlocale(locale.LC_ALL, locale_name)
File “/usr/lib/python3.6/locale.py”, line 598, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File “/usr/bin/lutris”, line 31, in
sys.stderr.write(“Unsupported locale %s. Try running with LC_ALL=C.\n” % locale_name)
TypeError: not all arguments converted during string formatting

Add LC_ALL=C to the .desktop file in /usr/share/applications/lutris.desktop

So it looks like this:
