Some packages are 'kept back' or 'on hold'

• During an apt-get update or apt-get upgrade not all packages get upgraded:

• There we can see four packages haven't been upgraded, even though newer packages are available.

• This is because two new packages were introduced, and these upgrades depend upon it.

• To correct this, run:

Apache2

• Apache2 has several command line tools to enable or disable features
• The commands a2enmod and a2ensite are particularly useful. http://old.nabble.com/a2ensite-koha-error-td26597287.html

Apache2 a2enmod

• Tool to enable a site: http://manpages.ubuntu.com/manpages/karmic/en/man8/a2enmod.8.html

  a2enmod is a script that enables the specified module within the
  apache2 configuration. It does this by creating symlinks within
  /etc/apache2/mods-enabled.

• Run:

Apache2 a2ensite

• Tool to enable a site: http://manpages.ubuntu.com/manpages/karmic/en/man8/a2ensite.8.html

  a2ensite is a script that enables the specified site (which contains a
  <VirtualHost> block) within the apache2 configuration. It does this by
  creating symlinks within /etc/apache2/sites-enabled.

Enable frame buffer

• Lookup in http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers for a corresponding value.

• Valid values:
  791 - 1024 x 768 @ 16
  792 - 1024 x 768 @ 24
  867 - 1400 x 900 @ 24
  799 - 1600 x 1200 @ 24

791 is a safe value
