7. Managing your bookworm system before the upgrade

Гэты дадатак утрымлівае інструкцыі, як перад абнаўленнем да trixie пераканацца, што Вы можаце ўсталёўваць альбо абнаўляць пакеты bookworm.

7.1. Абнаўленне сістэмы на базе bookworm

Basically this is no different from any other upgrade of bookworm you've been doing. The only difference is that you first need to make sure your package list still contains references to bookworm as explained in Checking your APT source-list files.

Калі сістэма абнаўляецца праз люстэрка Debian, яно будзе аўтаматычна абноўленае да апошняй рэвізіі bookworm.

7.2. Checking your APT configuration

If any of the lines in your APT sources files (see sources.list(5)) contain references to "stable", this is effectively pointing to trixie already. This might not be what you want if you are not yet ready for the upgrade. If you have already run apt update, you can still get back without problems by following the procedure below.

If you have also already installed packages from trixie, there probably is not much point in installing packages from bookworm anymore. In that case you will have to decide for yourself whether you want to continue or not. It is possible to downgrade packages, but that is not covered here.

As root, open the relevant APT sources file(s) (such as /etc/apt/sources.list or any file under /etc/apt/sources.list.d/) with your favorite editor, and check all lines beginning with

• deb http:

• deb https:

• deb tor+http:

• deb tor+https:

• URIs: http:

• URIs: https:

• URIs: tor+http:

• URIs: tor+https:

for a reference to "stable". If you find any, change "stable" to "bookworm".

If you have any lines starting with deb file: or URIs: file:, you will have to check for yourself if the location they refer to contains a bookworm or trixie archive.

Important

Do not change any lines that begin with deb cdrom: or URIs: cdrom:. Doing so would invalidate the line and you would have to run apt-cdrom again. Do not be alarmed if a cdrom: source line refers to "unstable". Although confusing, this is normal.

Пасля ўнясення зменаў захавайце файл і запусціце каманду

# apt update

каб узнавіць спіс пакетаў.

7.3. Performing the upgrade to latest bookworm release

To upgrade all packages to the state of the latest point release for bookworm, do

# apt full-upgrade

7.4. Removing obsolete configuration files

Before upgrading your system to trixie, it is recommended to remove old configuration files (such as *.dpkg-{new,old} files under /etc) from the system.
