Comment 6 for bug 1926223

@sclarkson: I can confirm that your early command does work around the problem:

`d-i preseed/early_command string \
  sed -i -e '/Package: libc6-udeb/{N;N;s/Version: 2.31-0ubuntu9.*/Version: 2.31-0ubuntu9.3/}' /var/lib/dpkg/status`

@guiverc: Unfortunately tty 2 and 3 won't load to run the command.
'-/bin/sh: error while loading shared libraries: __vdso_gettimeofday: invalid mode for dlopen(): Invalid argument'
