Bug description:
[ ubuntu-advantage-tools SRU info ]
[ Impact ]
If ubuntu-advantage-tools (u-a-t) is not already installed, but cloud-
init user-data includes "ubuntu_advantage" configuration data, then
cloud-init will try to install u-a-t. On install, u-a-t needs to start
ubuntu-advantage.service. ubuntu-advantage.service is ordered
After=cloud-config.service. This results in deadlock, preventing apt
from ever finishing. The apt lock is held forever and cloud-init never
continues.
The fix is to break the deadlock by removing the "After=cloud-
config.service" ordering dependency from ubuntu-advantage.service.
ubuntu-advantage.service should still wait until cloud-config.service
is done activating to do any work though, so that waiting is now
implemented in the python script that is executed by the service.
[ Test Plan ]
```
# Launch a lxd container with ubuntu_advantage cloudinit user-data:
lxc launch ubuntu-daily:bionic test --config
"user.user-data=#cloud-config\nubuntu_advantage: {}"
# Enter the container
lxc shell test
# Remove u-a-t
apt remove ubuntu-advantage-tools
# tell cloud init to clean and reboot
cloud-init clean --logs --reboot
# enter the container again
lxc shell test
# wait for cloud-init to finish
cloud-init status --wait
# if the bug is happening, that command will never finish
```
This test has been added as a regression test to u-a-t and will be run as
part of the validation for LP: #2048921 (see:
https://github.com/canonical/ubuntu-pro-client/blob/release-31/features/install_uninstall.feature#L116)
[ Where problems could occur ]
This does not remove the ordering dependency, but just changes how the
ordering dependency between ubuntu-advantage.service and cloud-
config.service is implemented. This difference in implementation could
cause different unexpected ordering problems to occur in the future.
The waiting function in python was designed such that it will
eventually continue if cloud-config.service takes longer than 20
minutes. If cloud-config.service takes 20 minutes doing an Ubuntu Pro
related operation (normal operations take less than 10 seconds at
most), then ubuntu-advantage.service could continue and potentially
error when it tries to do something in conflict with the ongoing
operation. Alternatively, if the wait was implemented incorrectly,
then ubuntu-advantage.service could stall forever unnecessarily if
cloud-config.service doesn't finish.
[Original Description]
During install of Ubuntu Server 22.04.3 you are asked if you want to
attach to Ubuntu Pro. If you do then following a reboot you cannot run
apt. cloud-init runs and installs ubuntu-advantage-tools which for
some reason never releases the lock file.
$ sudo apt dist-upgrade
Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is
held by process 994 (apt-get)
If you reboot at this point then you receive:
$ sudo apt dist-upgrade
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to
correct the problem.
