This appendix contains information on how to make sure you can install or |
| 11 |
|
|
upgrade &oldreleasename; packages before you upgrade to &releasename;. This should only be |
| 12 |
|
|
necessary in specific situations. |

<title>Upgrading your &oldreleasename; system</title> |

<para> |
| 17 |
|
|
Basically this is no different than any other upgrade of &oldreleasename; you've been |
| 18 |
|
|
doing. The only difference is that you first need to make sure your package |
| 19 |
|
|
list still contains &oldreleasename; packages as explained in <xref |
| 20 |
xerakko |
5596 |
linkend="old-sources"/>. |

If you upgrade your system using a Debian mirror, it will automatically be |
| 24 |
|
|
upgraded to the latest &oldreleasename; point release. |

If any of the lines in your <filename>/etc/apt/sources.list</filename> refer to |
| 32 |
xerakko |
5596 |
'stable', you are effectively already <quote>using</quote> &releasename;. If you have already run |
| 33 |
debacle |
5456 |
<literal>apt-get update</literal>, you can still get back without problems |
| 34 |
|
|
following the procedure below. |

If you have also already installed packages from &releasename;, there probably is not |
| 38 |
|
|
much point in installing packages from &oldreleasename; anymore. In that case you will |
| 39 |
|
|
have to decide for yourself whether you want to continue or not. It is |
| 40 |
|
|
possible to downgrade packages, but that is not covered here. |

Open the file <filename>/etc/apt/sources.list</filename> with your favorite |
| 44 |
|
|
editor (as root) and check all lines beginning with <literal>deb |
| 45 |
|
|
http:</literal> or <literal>deb ftp:</literal> for a reference to |
| 46 |
xerakko |
5596 |
<quote><literal>stable</literal></quote>. If you find any, change <literal>stable</literal> |
| 47 |
debacle |
5456 |
to <literal>&oldreleasename;</literal>. |
| 48 |
|
|
</para> |
| 49 |
|
|
<para> |
| 50 |
|
|
If you have any lines starting with <literal>deb file:</literal>, you will have |
| 51 |
xerakko |
5596 |
to check for yourself if the location they refer to contains an &oldreleasename; or a &releasename; |
| 52 |
debacle |
5456 |
archive. |

<para> |

Do not change any lines that begin with <literal>deb cdrom:</literal>. |
| 57 |
|
|
Doing so would invalidate the line and you would have to |
| 58 |
|
|
run <command>apt-cdrom</command> again. Do not be alarmed if a |
| 59 |
|
|
'cdrom' source line refers to <quote><literal>unstable</literal></quote>. |
| 60 |
|
|
Although confusing, this is normal. |
