Reproduced on kinetic daily image with autoinstall. Related to running ubuntu-drivers. For unclear reasons I haven't seen this happen outside of autoinstall (timing?)

We believe a fix for this can be found in Subiquity 22.10.1. On
install you will be offered to update to the new version of the
installer if network is available, or you can perform a manual update
by running the follwing in a terminal:
sudo snap refresh subiquity

We believe this issue has been resolved in Subiquity 23.04.2.

If you had tested this with a pre-final version of Ubuntu 23.04, it's
recommended to download the final install media.

For testing with Ubuntu Server 22.04.x or 20.04.x, when running
Subiquity, you should offered a new version of the installer. Please
take that update to version 23.04.2 or later to get the fix.

If this is still a problem for you, please make a comment and set the state
back to New. Thank you for the bug report.
