OS with Aimpanel

Best choice - upgrades all system packages with Aimpanel.

Make backup before this process!

apt-get update && apt-get dist-upgrade

Only Aimpanel

May be problematic, use this if you know what are you doing or Aimpanel staff tolds you so.

Remember, using old system packages could expose you to attacks!

apt-get update && apt-get install aimpanel*
