This should be a bug report, and it just started happening yesterday, but I’m not sure where to file bugs like this…

After adding the repository to apt:

ubuntu@influx:~$ sudo apt install influxdb

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

The problem stems from a bad useradd command in the preinst script:

#!/bin/bash
set -e

LOG_DIR=/var/log/influxdb
DATA_DIR=/var/lib/influxdb

if ! id influxdb &>/dev/null; then
    useradd --system -u -m influxdb -s /bin/false -d "${data_dir}"
fi

Two problems:

  • The -u should be a -U. -u expects a UID.
  • The -d "${data_dir}" should be -d "${DATA_DIR}". The lowercase variable doesn’t exist.

A workaround is to run the correct useradd command before installing the package.

sudo useradd --system -U -m influxdb -s /bin/false -d /var/lib/influxdb
