7. Managing your bookworm system before the upgrade

Tässä liitteessä neuvotaan miten varmasti saadaan asennettua tai päivitettyä julkaisun bookworm paketteja ennen päivitystä julkaisuun trixie.

7.1. bookworm-järjestelmän päivitys

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.

Jos päivität järjestelmän Debianin asennuspalvelinta käyttäen, se päivitetään automaattisesti viimeisimpään julkaisun bookworm korjauspäivitykseen.

7.2. Checking your APT source-list files

If any of the lines in your APT source-list 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.

Jos julkaisusta trixie on jo asennettu paketteja, ei luultavasti ole järkeä asentaa enää paketteja julkaisusta bookworm. Tässä tapauksessa on tehtävä päätös jatketaanko vai ei. Pakettien palauttaminen vanhaan versioon on mahdollista, mutta sitä ei käsitellä tässä.

As root, open the relevant APT source-list file (such as /etc/apt/sources.list) 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.

Tärkeä

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.

Mikäli olet tehnyt muutoksia, tallenna tiedosto ja suorita

# apt update

pakettiluettelon päivittämiseksi.

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.
