Part of NetOrk/netork#738.

An unattended upgrade cut off while it built an initrd left a kernel package half-configured on an Ubuntu host. For three months apt refused every upgrade, while apt.systemd.daily exited quietly and the timers reported success.

HOST_STATUS_COMMAND now also reads, without root:

  • dpkg's state, the way apt checks it: numbered files left in /var/lib/dpkg/updates, or a package half-installed, unpacked, half-configured, waiting for triggers or flagged for reinstallation (dpkg-query -W -f='${db:Status-Abbrev} ${Package}', filtered on the host). While dpkg, apt, aptitude or unattended-upgrade runs, packages are halfway on purpose, so the answer is then None.
  • When the host's own automatic updates last succeeded: /var/lib/apt/periodic/upgrade-stamp, which apt.systemd.daily touches only after unattended-upgrade succeeded, and the interval of APT::Periodic::Unattended-Upgrade in apt's units (s, m, h, d; a bare number is days; always is 0). update-success-stamp is not read: every apt-get update touches it, whoever runs it.

HostStatusDict gains package_manager_interrupted, interrupted_packages ([{name, state}]), auto_updates_last_success (Unix time) and auto_updates_interval (seconds), all NotRequired. Version 4.3.0.

Tests

  • tests/test_host_status.py: the aris fixture (iF linux-image-6.8.0-134-generic), every halfway state, the journal alone, tmp.i ignored, a running package manager, no dpkg; the stamp and every interval unit.
  • The whole suite: 481 passed; mypy strict clean.
  • napalm-linux, napalm-proxmox, napalm-bsd, napalm-openmediavault and napalm-opnsense pass against this branch.
  • The command run on an Ubuntu host parses cleanly (interrupted: False).
Part of NetOrk/netork#738. An unattended upgrade cut off while it built an initrd left a kernel package half-configured on an Ubuntu host. For three months apt refused every upgrade, while `apt.systemd.daily` exited quietly and the timers reported success. `HOST_STATUS_COMMAND` now also reads, without root: - **dpkg's state, the way apt checks it:** numbered files left in `/var/lib/dpkg/updates`, or a package half-installed, unpacked, half-configured, waiting for triggers or flagged for reinstallation (`dpkg-query -W -f='${db:Status-Abbrev} ${Package}'`, filtered on the host). While dpkg, apt, aptitude or unattended-upgrade runs, packages are halfway on purpose, so the answer is then `None`. - **When the host's own automatic updates last succeeded:** `/var/lib/apt/periodic/upgrade-stamp`, which `apt.systemd.daily` touches only after unattended-upgrade succeeded, and the interval of `APT::Periodic::Unattended-Upgrade` in apt's units (s, m, h, d; a bare number is days; `always` is 0). `update-success-stamp` is not read: every `apt-get update` touches it, whoever runs it. `HostStatusDict` gains `package_manager_interrupted`, `interrupted_packages` (`[{name, state}]`), `auto_updates_last_success` (Unix time) and `auto_updates_interval` (seconds), all `NotRequired`. Version 4.3.0. ## Tests - `tests/test_host_status.py`: the aris fixture (`iF linux-image-6.8.0-134-generic`), every halfway state, the journal alone, `tmp.i` ignored, a running package manager, no dpkg; the stamp and every interval unit. - The whole suite: 481 passed; mypy strict clean. - napalm-linux, napalm-proxmox, napalm-bsd, napalm-openmediavault and napalm-opnsense pass against this branch. - The command run on an Ubuntu host parses cleanly (`interrupted: False`).

An unattended upgrade cut off while it built an initrd left a kernel package
half-configured on an Ubuntu host. For three months apt refused every upgrade,
while apt.systemd.daily exited quietly and the timers reported success

  /var/lib/dpkg/updates, or a package half-installed, unpacked,
