The mailing list for listmasters using Sympa

[<address@concealed>]

Hello,
I installed Sympa 6.1.23 with apt-get on my Debian Jessie distribution.

My problem is that I'd like to have Sympa in Italian, but I can't change
language.
Some informations for you:
- My debian distribution is in English.
- I opened /etc/sympa/sympa.conf and set this:

supported_lang  it
lang  it

When I login and go to preferences, I can select only the "it_IT" language,
but the interface is always in English.

Unfortunately, since I see only English, I tried to compile Sympa by myself
from source, as an alternative, , because the version is newer, so now I
really don't know if the path:
/usr/lib/sympa/locale
was created by the compiled version or by apt-get install version.
Anyway, how can I configure Sympa in order to handle the po italian file?
Why I can't change the language?

Thank you!
