System upgrade

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

Remove packages

Note

Packages removing is no more complicated than installation. For that you need to know package name, which to you want to remove and take note to messages by APT system.

To remove anything, you need to know what to possible to remove. For example, packages of programs, which you already not use, or did not use in general.

At removing of packages you need to follow the rule:

  • Not every package, which you don't use is not needed

The rule reports what soft, which you use, can use package, which you want to remove. Usual dependencies are built correctly and APT system always warn about which packages need to remove with specified. Should not be remove general system packages, you can to broke correct functionality of system. In this case apt will ask, do you really user to sure in own actions.

For example: 

# apt-get remove coreutils
<big list of packages>
...
WARNING: The following essential packages will be removed
This should NOT be done unless you know exactly what you are doing!
...
You are about to do something potentially harmful
To continue type in the phrase 'Yes, do as I say!'
