[Koha] Koha 3.12 installation problem

[Viviane Ventura]

Hi,

When i try to install a koha instance, the installation stops at this point:

# koha-create --create-db library
sed: can't read /etc/koha/apache-site.conf.in: No such file or directory

It seems that the installation package koha-common is not creating the
configuration files of Apache (or any other configuration file in
/etc/koha).

How can i solve this?

thanks for help.
