[Bug 1764172] Re: Unable to change hostname from the one specified during Bionic server installation
(In addition to the one mentioned by WirelessMoves, I found several other Ubuntu Forum threads as well as blog posts, etc. which recommend working around this problem by editing the /etc/cloud/cloud.cfg file to set the "preserve_hostname:" line's value to "true". However, that approach means there would be a conffile conflict whenever the cloud- init package is upgraded, so a better solution in the long run is probably to create a new file in /etc/cloud/cloud.cfg.d/ with that setting instead.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764172 Title: Unable to change hostname from the one specified during Bionic server installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1764172/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1764172] Re: Unable to change hostname from the one specified during Bionic server installation
Presumably the ideal solution would be for Subiquity to hand off to cloud-init in a manner that really only ran on that very first boot of the new system. However, assuming that a true fix to that situation is too invasive to be included into Bionic at this point, it seems like it might be a good idea to at least mention the issue (and recommended workaround) in the Bionic release notes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764172 Title: Unable to change hostname from the one specified during Bionic server installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1764172/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1764172] Re: Unable to change hostname from the one specified during Bionic server installation
When installing Ubuntu Server using Subiquity (i.e. using the
ubuntu-18.04-live-server-amd64.iso installer image), the user is
prompted to enter a hostname for the new installation (along with
username/password info, etc.)
At the very end of the Subquity run, it writes this info into
var/lib/cloud/seed/nocloud-net/user-data within the installation target
filesystem (e.g.
==
root@bionic:/var/lib/cloud# head -6 seed/nocloud-net/user-data
#cloud-config
growpart: {mode: 'off'}
hostname: bionic
locale: en_US.UTF-8
resize_rootfs: false
users:
==
)
When the newly-installed system is booted for the first time, this file
causes cloud-init finish up the configuration of the new instance --
include setting the new system's hostname to the specified value as part
of that initial boot.
However, cloud-init on Bionic (e.g. 19.2-36-g059d049c-0ubuntu2~18.04.1)
calls the cc_set_hostname module upon every boot (from within the
cmd/main.py:main_init() function, thus overriding the normal "per-
instance" frequency for the module)...
...and because the "hostname" cloud-config parameter is found to be set,
the cc_set_hostname module will always re-write /etc/hostname back to
the originally-entered hostname at that point -- unexpectedly undoing
the user's manual change to the file.
