Bug#993164: proftpd-core: When upgrading from Buster to Bullseyes, the installation of ProFTPd fails

[Andreas Guenther]

Package: proftpd-core
Version: 1.3.7a+dfsg-12
Severity: serious
Justification: 1

Dear Maintainer,

   This error occurred for the first time when upgrading the system from Buster to Bullseye:
   dpkg: Fehler beim Bearbeiten des Paketes proftpd-mod-crypto (--configure):
   Abhängigkeitsprobleme - verbleibt unkonfiguriert
   dpkg: Abhängigkeitsprobleme verhindern Konfiguration von proftpd-mod-wrap:
   proftpd-mod-wrap hängt ab von proftpd-core (= 1.3.7a+dfsg-12); aber:
   Paket proftpd-core ist noch nicht konfiguriert.
   .
   .
   Fehler traten auf beim Bearbeiten von:
    proftpd-core
    proftpd-mod-crypto
    proftpd-mod-wrap
    proftpd-basic

   Then I deleted all the packages involved and tried to reinstall them with the same result:
    dpkg --remove proftpd-basic proftpd-core proftpd-mod-crypto proftpd-mod-wrap
    apt install proftpd-core proftpd-basic proftpd-mod-crypto proftpd-mod-wrap
   
   After deleting all packages again, I only installed proftpd-core:
    apt install proftpd-core

   See "systemctl status proftpd.service" and "journalctl -xe" for details.
   dpkg: Fehler beim Bearbeiten des Paketes proftpd-core (--configure):
     »installiertes proftpd-core-Skript des Paketes post-installation«-Unterprozess gab den Fehlerwert 1 zurück
   Fehler traten auf beim Bearbeiten von:
   proftpd-core
   
   The package obviously cannot be installed due to the proftpd-core script.
   
   My expectation of you would be to make ProFTPd installable.

   Best regards
   Andreas Günther
