System upgrade

Attention! In ALT Linux is not customary to partial system upgrade via apt-get upgrade! You can drop own system with using this command! You need use only apt-get dist-upgrade instead it.

Attention! Do not hurry to press ENTER or Y. Study carefully, what APT suggets to remove, replace, upgrade or install. Truly you accepted with his changes? Never don't add option -y for control of APT.

For upgrade system to actual condition (except kernel), use next command:

# apt-get dist-upgrade

Example of run:

Note: When for you need upgrade several packages, you need confirm action with enter Y

# apt-get dist-upgrade
