install failed on fresh debian trixie

[PierreM59]

Hello all !
I tried to install fog from git on my debian trixie.
installfog.sh failed with installation of isc-dhcp-server

“Préparation du dépaquetage de …/isc-dhcp-server_4.4.3-P1-8_amd64.deb …
Dépaquetage de isc-dhcp-server (4.4.3-P1-8) sur (4.4.3-P1-8) …
Paramétrage de isc-dhcp-server (4.4.3-P1-8) …
Job for isc-dhcp-server.service failed because the control process exited with error code.
See “systemctl status isc-dhcp-server.service” and “journalctl -xeu isc-dhcp-server.service” for details.
invoke-rc.d: initscript isc-dhcp-server, action “restart” failed.”

I tried to reinsatll isc-dhcp-server separately on my computer but it could not work

I searched for a bug in https://www.isc.org/dhcp/
and there I found that this pacakge is not maintained any more.

“ISC has announced the end of maintenance for ISC DHCP as of the end of 2022. ISC will continue providing professional support services for existing subscribers, but does not intend to issue any further maintenance releases. For resources that may help in migrating your existing ISC DHCP server deployment to our newer DHCP server, Kea, please see this page.”

Will foginstall.sh be modified, or is a by-pass possible ?
