[Bug 2064132] Re: images without snapd installed error on `update_packages: true` user-data
** Description changed:
[ Impact ]
* SRU of cloud-init 24.1.3 to Focal, Jammy and Mantic introduced a
regression where cloud-init will attempt to call `snap refresh` on new
Ubuntu instance launches if the Ubuntu image does not contain snapd deb
package and optional #cloud-config user-data is provided which contains
`upgrade_packages: true`.
* Such optional user-data on custom ubuntu images will result in cloud-init
exiting in error condition as seen from cloud-init status due to the following
error message:
- ('package_update_upgrade_install', ProcessExecutionError("Unexpected error
while running command.\nCommand: ['snap', 'refresh']\nExit code: -\nReason:
[Errno 2] No such file or directory: b'snap'\nStdout: -\nStderr: -"))
This only affects new custom Ubuntu image launches where both of the
following conditions are met:
1. image is a custom ubuntu image which does not contain snapd deb package
2. At instance launch, optional #cloud-config user-data contains
`package_upgrade: true`
Ubuntu cloudimages published by Canonical for Focal, Jammy and Mantic
all currently have the snapd deb package installed.
Even for custom Ubuntu images without snapd deb package installed, this
issue is only triggered when #cloud-config contains the optional
`package_upgrade: true` during instance launch.
This error log does cause cloud-init status to exit non-zero, but it
doesn't affect the integrity of the configuration applied to the system.
It is just an undesirable error log message for an unsupported (snap)
package manager within the environment.
[ Test Plan ]
* # launch ubuntu cloud images in LXC, remove snapd, provide
"#cloud-config\npackage_upgrade:true" as user-data and clean reboot to force
cloud-init to attempt to upgrade any package managers (snap and apt) where
applicable.
* confirm no snap command present in image
* check cloud-init status --format=yaml to ensure no errors
* grep snap.*refresh /var/log/cloud-init.log to assert no stray snap refresh
is attempted on an image without snap

Please also confirm, via the test plan, that if the image has the snap deb installed, that the snaps will be upgraded, i.e., that we don't break the normal use case with canonical images. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064132 Title: images without snapd installed error on `update_packages: true` user- data To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/2064132/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 2064132] Re: images without snapd installed error on `update_packages: true` user-data
Given that all Canonical Ubuntu images (including server minimal and cloud minimal images) contain snapd deb package, this is not a critical path concern for Canonical stable supported Ubuntu images. So, `regression-update` tag is dropped for our specific support paths as this doesn't regress image streams we claim to support. This SRU remains queued in unapproved queue for Focal, Jammy, Mantic and Novble with priority for next SRU reviewer when time is available as we do want this fixed shortly to better support any derivative Ubuntu images which may have dropped snapd from their images in an effect to shrink that image size even further. ** Tags removed: regression-update -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064132 Title: images without snapd installed error on `update_packages: true` user- data To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/2064132/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
