Looks like there are two problems:

  1. django.core.exceptions.FieldError: Cannot resolve keyword 'n_pings' into field. Choices are: body_raw, created, exitstatus, id, kind, method, n, object_size, owner, owner_id, remote_addr, rid, scheme, ua
  2. ValueError: The ADMINS setting must be a list of 2-tuples. (which loops a few times)

The first, n_pings, is the main one. I don't understand, because I did run migrations:

sudo -u healthchecks /opt/healthchecks/venv/bin/python /opt/healthchecks/healthchecks/manage.py showmigrations |egrep -v '(\[X]|^[a-z])'
System check identified some issues:

WARNINGS:
?: (hc.api.W002) settings.EMAIL_HOST is not set, cannot send email
        HINT: See https://github.com/healthchecks/healthchecks#sending-emails
 (no migrations)

However, EMAIL_HOST is set in the environment. Just like for the second problem, ADMINS. Both are set as an environmental variable by Systemd from .env file. They are well defined in process environment:

sudo cat /proc/598251/environ |egrep -oa '(EMAIL_HOST|ADMINS)=[^A-Z]*'
ADMINS=root@example.com
EMAIL_HOST=localhost

Did I missed something for the upgrade?

Choices are: body_raw, created, exitstatus, id, kind, method, n, object_size, owner, owner_id, remote_addr, rid, scheme, ua` 2. `ValueError: The ADMINS setting must be a list of 2-tuples.` (which loops a few times) The first, `n_pings`, is the main one. I don't understand, because I did run migrations: ```sh sudo -u healthchecks /opt/healthchecks/venv/bin/python /opt/healthchecks/healthchecks/manage.py showmigrations |egrep -v '(\[X]|^[a-z])' System check identified some issues: WARNINGS: ?: (hc.api.W002) settings.EMAIL_HOST is not set, cannot send email HINT: See https://github.com/healthchecks/healthchecks#sending-emails (no migrations) ``` However, `EMAIL_HOST` is set in the environment. Just like for the second problem, `ADMINS`. Both are set as an environmental variable by Systemd from `.env` file. They are well defined in process environment: ```sh sudo cat /proc/598251/environ |egrep -oa '(EMAIL_HOST|ADMINS)=[^A-Z]*' ADMINS=root@example.com EMAIL_HOST=localhost ``` Did I missed something for the upgrade?

The The ADMINS setting must be a list of 2-tuples. error makes me think you don't have the correct version of Django installed. Did you install the dependencies listed in requirements.txt?

Thank you very much!
Indeed, I completely missed out this step.
Sorry for wasting you time!
