ImportError: libffi.so.7

[sir_renater]

Hello,

We would like to update our Wapt server from version 2.3 to version 2.4 by following the documentation below:
- https://www.wapt.fr/fr/doc/wapt-server-upgrade.html

All the steps of the update worked except the last one, launching postconf.sh. I get the error message below.

Indeed, we only have the libffi.so.7 library installed, only version 8.

root@xxxxxxxxxxxxx:/opt/wapt/waptserver/scripts# ./postconf.sh
Traceback (most recent call last):

ImportError: libffi.so.7: cannot open shared object file: No such file or directory

Is this a known issue on your end?

Hello sir,

OS version, etc. (see forum rules).

Could you have perhaps upgraded your Debian/Ubuntu version at the same time?
