** Description changed: Recent downstream ubuntu-specific changes in needrestart version - 3.6-7ubuntu1 [1] set Ubuntu into autorestart mode during non-interactive + 3.6-7ubuntu1 [1] set Ubuntu into autorestart mode when non-interactive apt-get dist-upgrade is being performed. This causes an acute issue for cloud-init when #cloud-config user-data tries to perform apt-get dist-upgrade and package installs via user- data[2] like the following: #cloud-config package_update: true package_upgrade: true packages: [sl] Since cloud-init runs apt-get dist-upgrade in cloud-final.service in non-interactive mode, Ubuntu's behavior looks to set the default "opt_r" mode to "a" (automatic). This causes problems when cloud-init package is also being upgraded by dist-upgrade as needrestart will collect the currently running cloud-final.service and determine it is a target for automtic restart. The immediate SIGTERM of cloud-final.service prevents cloud-init from completing any of the remaining config modules in the cloud-final boot stage, notably, the additional package installs requested by the `packages:` directive in user data. Given that cloud-final.service is a oneshot service, that can spawn apt- get dist-upgrade. I'd propose that minimally Ubuntu initially carries a downstream patch to skip automated restart of cloud-final.service[3]. I don't see an easier way to inject other skip regex into /etc/needrestart/needrestart.conf via /etc/needrestart/conf.d/cloud- init.conf that would allow us to augment the list of skip regexs on a per-package basis.
