If you're looking for a good installation script for LedgerSMB on Debian, you could use the commands from the Dockerfile (https://github.com/ledgersmb/ledgersmb-docker/blob/1.11/Dockerfile) which installs LedgerSMB 1.11 on Debian Bookworm. Important to note is that the lines from 68 and later do the actual installation of LedgerSMB; the lines before 68 are trying to map the Perl dependencies from the project's "cpanfile" to Debian package names.
