Measured on erplibre-ubuntu-2404: unattended-upgrades fired in the middle of
an Odoo 12->13 migration and restarted the PostgreSQL cluster three times
(« received fast shutdown request »). OpenUpgrade lost its connection and the
intermediate database was left half migrated.
On a development VM the ERPLibre installer now turns off unattended-upgrades
and the apt-daily timers, and drops an apt.conf.d snippet so they stay off
across reboots. dnf-automatic gets the same treatment on Fedora. It runs right
after the cloud-init wait and before the apt-get calls, so apt-daily can no
longer grab the lock between the two either -- the same contention that made
« apt-get update » fail during deployment.
Production VMs are left untouched: automatic security updates must stay on
there. The switch is the existing dev/prod answer, already threaded down to
_qemu_erplibre_remote_cmd.
