FWIW, because Focal's deb-systemd-invoke doesn't use --quiet we end up getting a clearer error there:

Status in init-system-helpers package in Ubuntu: New Status in krb5 package in Ubuntu: New Bug description: I have a fresh install of Ubuntu Server 22.04.01 LTS. After installing the server and running all updates, I run the following command: apt -y install slapd ldap-utils schema2ldif sasl2-bin libsasl2-modules-gssapi-mit krb5-kdc-ldap krb5-admin-server krb5-kdc This will be installing krb5-kdc 1.19.2-2. This is in preparation for setting up an OpenLDAP server, a Kerberos server with an LDAP backend, and saslauthd for pass-through authentication. krb5-kdc was auto-selected when running the steps in the guide here in my development environment: https://ubuntu.com/server/docs/service-kerberos-with-openldap-backend When installing that, I get the following in the output: Setting up krb5-kdc (1.19.2-2) ... Created symlink /etc/systemd/system/multi-user.target.wants/krb5-kdc.service → /lib/systemd/system/krb5-kdc.service. Could not execute systemctl: at /usr/bin/deb-systemd-invoke line 142. I do get the prompts for the realm, kdc, and admin server hostnames, and they are reflected in /etc/krb5.conf. If I then run the following: dpkg-reconfigure krb5-kdc I am prompted for whether I want the package to create the Kerberos KDC configuration automatically, and when I say yes, it then repeats the following error: Could not execute systemctl: at /usr/bin/deb-systemd-invoke line 142. I cannot find any further debug in the syslog or anything to indicate what the root cause is; the list of packages here are all installed together on a separate development server where I experimented with the configuration I will be deploying here in production so I don't think it's incompatible packages in the install list, but I am open to feedback on that.
