[Bug 1996619] Re: Setfont error due to deprecated PIO_FONTX ioctl

[Launchpad Bug Tracker]

This bug was fixed in the package kbd - 2.5.1-1ubuntu1

---------------
kbd (2.5.1-1ubuntu1) lunar; urgency=medium

  * Merge from Debian unstable.  Remaining changes:
    - Add setfont, kbd_mode, and loadkeys to initramfs for console-setup.
    - Added initramfs hook to have setfont/loadkeys available in initramfs.
    - Use ckbcomp to get the keyboard layout if other data files are not
      available.
    - Change loadkeys to find any console not in raw mode when invoked
      without an explicit console parameter, in case the foreground console
      is in raw mode.
    - Add setvtrgb to kbd-udeb.
    - Fix incorrect keymap sanity check in loadkeys_ckbcomp.diff.
    - debian/control: Depend on console-setup | console-setup-mini, since
      console-setup-mini also Depends on kbd now through console-setup-linux.
    - debian/patches/loadkeys_find_usable_console.diff: fix wrong type
      argument to ioctl(..., KDGKBMODE), which causes consoles to not be
      correctly detected on 64-bit archs.  LP: #1621824.

  * Removed obsolete patches/changes:
    -  d/p/fix_use_after_free.patch to clean up a use-after-free of
       pipe_cmd, now merged upstream.

  * New upstream release drops deprecated ioctls removed in Linux v5.12.
    LP: #1996619.

kbd (2.5.1-1) unstable; urgency=medium

  * Team upload.

  [ Andreas Henriksson ]
  * New upstream release.
  * Unfuzz debian/patches/Miscellaneous-manpage-corrections-and-additions.patch
  * Unfuzz debian/patches/Check-for-X-in-kbd_mode.patch
  * Revert "Cherry-pick no install libtswrap internal library"
  * Let `gbp pq <import|export>` refresh patches
  * Bump debhelper from old 10 to 13.
  * Set debhelper-compat version in Build-Depends.
  * Set upstream metadata fields: Bug-Database, Bug-Submit.
  * debian/copyright: Update paths of moved files

  [ nick black ]
  * refer to deallocvt(8), not disalloc(8) (Closes: #989525)

  [ Osamu Aoki ]
  * update d/control for console-setup (Closes: #998086)

Title:
  Setfont error due to deprecated PIO_FONTX ioctl

Status in subiquity:
  New
Status in kbd package in Ubuntu:
  Fix Released
Status in kbd source package in Jammy:
  New

Bug description:
  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+ or 
  to understand the root cause and troubleshoot as to why it's broken and resolve 
  it there.

  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.
