hours, and then in the -proposed repository.

Please help us by testing this new package.  See

to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
kinetic to verification-done-kinetic. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-kinetic. In either case, without details of your
testing we will not be able to proceed.

Further information regarding the verification process can be found at

Bug description:
  [Impact]

  There is an error message that get thrown in in syslog.
  There is a suggestion to fix by upgrading the KDB package to version 2.5.1+ (upstream) has a fix.

  It is caused by this line in subiquity
  https://github.com/canonical/subiquity/blob/46f671d14d57a5da6bc3d60b1da6715b43954f0d/bin/subiquity-service#L11

  It's due to PIO_FONTX ioctl removed from kernel since 5.12
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ff2047fb755d4415ec3c70ac799889371151796d

  In 2.4.5 of kbd which provide setfont in user space, they already
  switched over to use KDFONTOP only.
