Instructions how to upgrade installed Ubuntu system to Baltix GNU/Linux :
Baltix is based on Ubuntu, so, you could just install ubuntu-defaults-baltix or baltix-default-settings package and baltix-desktop metapackages (or separate metapackages - baltix-admin, baltix-office, baltix-edu-games, baltix-graphics, baltix-lang-support, baltix-multimedia, baltix-network, baltix-utils, baltix-win-dos-support) from official Baltix software repositories:
deb http://ppa.launchpad.net/baltix-members/ubuntu/ xenial main restricted universe #Main Baltix2016-Ubuntu16.04 software source
#deb http://ftp.akl.lt/Linux/Baltix/Baltix-Ubuntu-packages xenial main #Additional Baltix2016-Ubuntu16.04 software source
Don't forget to reload the information about available software (apt-get update) and upgrade all your upgradeable packages after you install ubuntu-defaults-baltix or baltix-default-settings package - there are lots of fixed and improved packages in Baltix, comparing to Ubuntu stable version :)
If you like to type commands in terminal - just execute these commands:
sudo apt-add-repository ppa:baltix-members/ppa && sudo apt-get update
sudo apt-get install ubuntu-defaults-baltix baltix-default-settings && sudo apt-get update
sudo apt-get --no-install-recommends install baltix-admin baltix-office baltix-edu-games baltix-graphics baltix-lang-support baltix-multimedia baltix-network baltix-win-dos-support baltix-utils
Also there is a repository of "testing" packages:
#deb http://ppa.launchpad.net/baltix/ubuntu/ xenial main restricted universe multiverse #Proposed software for Baltix2016/Ubuntu16.04
Software repositories for older or newer Baltix versions are the same, just replace "xenial" with other Ubuntu version codename, which you need, for example if you wanna make Baltix from installed Ubuntu 14.04 version you should install baltix-default-settings and baltix-desktop metapackages from these Baltix software repositories:
deb http://ftp.akl.lt/Linux/Baltix/Baltix-Ubuntu-packages trusty main
deb http://ppa.launchpad.net/baltix-members/ubuntu/ trusty main restricted universe multiverse
