Description Philipp Hahn univentionstaff 2020-01-30 10:19:52 CET
1. Missing dependency "cloud-init" -> "python3-oathlib" -> "python3-blinker" (see bug #46294 comment 3)
2. "cloud-init" is "Python 3" since UCS-4.3, while "univention-cloud-init" still installes to "Python 2" cp /usr/lib/python2.7/dist-packages/cloudinit/config/cc_ucs_setup.py 

Work-around: enable unmaintained (see Bug #39038) +
  cp /usr/lib/python2.7/dist-packages/cloudinit/config/cc_ucs_setup.py /usr/lib/python3/dist-packages/cloudinit/config/
Comment 1 Philipp Hahn univentionstaff 2020-01-30 10:54:10 CET
GOTCHA: "univention-cloud-init" does NOT call "/usr/lib/univention-system-setup/scripts/setup-join.sh" by itself; it ONLY writes the profile to "/var/cache/univention-system-setup/profile"!

Reading <https://docs.software-univention.de/installation.html#appliance:use:cloudinit> you also can/should provide two other files
before calling "setup-join.sh".
It would be good if u-c-i would support that as well AND would call "s-j.sh" itself!

It is more subtile than that: "setup-join.sh" is called by "/etc/init.d/univention-cloud.init", but that declares no dependency on "cloud-init" and thus is reordered by systemd to be started in *parallel* with it; this leads to the profile not yet being written and u-c-i skipping the call:

 41 »···dh_installinit -punivention-cloud-init --no-start -u"defaults 95"

# ls -1 /etc/init.d/*cloud* /etc/rc2.d/*cloud*
/etc/init.d/univention-cloud-init-prepare-boot <=== MISSING in rc2?

( cloud-config.serive || univention-cloud-init.service ) →
cloud-final.service →

Fixed in branch <git:phahn/50759_cloud-init>

Does this have to do with Bug #49171 ?
