Thank you for taking the time to report this bug and helping to make Ubuntu better.

Lubuntu 22.04 LTS is tested & supported only using the `calamares` installer.

As such I've marked this bug report as 'invalid'. If you believe I'm in error, please leave a comment explaining why, and the status can be returned to 'new'.

FYI: I checked both Lubuntu's jammy manifest & booted a live system and no `ubiquity` was installed.
