[Koha] Can't run auth_show_hidden_data.pl script

[Prof. Lisandro Laura]

Hi everyone!
I was upgrading from 17.05.04 to 17.05.06 and the following showed up:
"Bug 18811 fixed an inconsistency in the visibility settings for
authority frameworks. It is recommended that you run script
misc/maintenance/auth_show_hidden_data.pl to check if you have data in
hidden fields and adjust your frameworks accordingly to prevent data
loss when editing such records"

I was traying to run the script:
perl ./usr/share/koha/bin/maintenance/auth_show_hidden_data.pl

But I get the following error:

"Can't locate Koha/Authorities.pm in @INC (you may need to install the
Koha::Authorities module) (@INC contains: /etc/perl
/usr/local/lib/x86_64-linux-gnu/perl/5.20.2

./usr/share/koha/bin/maintenance/auth_show_hidden_data.pl line 28.
BEGIN failed--compilation aborted at
./usr/share/koha/bin/maintenance/auth_show_hidden_data.pl line 28."

What can I do?

Thank you in advance,
Lisandro
