ubuntu unattended setup and postinstall script

some observations when using the stick to set up cob4-18 (323):

• setting up udev rules via PostInstall failed - we had to remove /dev/usb* (@ipa-bnm, correct?) first, then re-run
• cob-start still has a hardcoded ping h1 which is not available on cob4-18 (base-only)
• we still need to add a PostInstall step for running the kickstart-robot.sh - see #193
• the locale is not set correctly, it is

  robot@cob4-13-b1:~$ locale
  LANG=en_US
  LANGUAGE=en_US:
  LC_CTYPE="en_US"
  LC_NUMERIC=de_DE.UTF-8
  LC_TIME=de_DE.UTF-8
  LC_COLLATE="en_US"
  LC_MONETARY=de_DE.UTF-8
  LC_MESSAGES="en_US"
  LC_PAPER=de_DE.UTF-8
  LC_NAME=de_DE.UTF-8
  LC_ADDRESS=de_DE.UTF-8
  LC_TELEPHONE=de_DE.UTF-8
  LC_MEASUREMENT=de_DE.UTF-8
  LC_IDENTIFICATION=de_DE.UTF-8
  LC_ALL=

  but it should be, i.e. all UTF-8

  robot@cob4-13-b1:~$ locale
  LANG=en_US.UTF-8
  LANGUAGE=en_US:
  LC_CTYPE="en_US.UTF-8"
  LC_NUMERIC=de_DE.UTF-8
  LC_TIME=de_DE.UTF-8
  LC_COLLATE="en_US.UTF-8"
  LC_MONETARY=de_DE.UTF-8
  LC_MESSAGES="en_US.UTF-8"
  LC_PAPER=de_DE.UTF-8
  LC_NAME=de_DE.UTF-8
  LC_ADDRESS=de_DE.UTF-8
  LC_TELEPHONE=de_DE.UTF-8
  LC_MEASUREMENT=de_DE.UTF-8
  LC_IDENTIFICATION=de_DE.UTF-8
  LC_ALL=

  I fixed this with (needs to be done on every PC!):

  • sudo dpkg-reconfigre locales, then unselect de_DE ISO-8859-1/en_US ISO-8859-1 and select de_DE UTF-8/en_US UTF-8 instead, press OK and select en_US UTF-8 as default locale on the next screen, press ok
  • then run sudo update-locale LANG=en_US.UTF-8 and sudo update-locale LANGUAGE=
  • then log out and log in and check again with locale
