[ledgersmb-users] Debian packages for LedgerSMB

Hi, As far as I have understood, there are two sorts of Debian packages for LedgerSMB : * Debian regular repositories just contain packages called « ledgersmb » ; * your repository apt.ledgersmb.org contains packages with names like « ledgersmb-1.5 » and « ledgersmb-1.5-apache ». So, I feel a bit lost... Is there one preferred sort of package ? Are some of these obsolete ? Regards.
