7. Håndter dit bookworm-system før opgraderingen
Dette bilag indeholder information om, hvordan du kontrollerer, at du kan installere eller opgradere pakker fra bookworm inden du opgraderer til trixie.
7.1. Opgradering af dit bookworm-system
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.
Hvis du opgraderer dit system via et Debianspejl, vil systemet automatisk blive opgraderet til den seneste punktudgave (point release) af 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.
Hvis du allerede har installeret pakker fra trixie, er der ikke længere meget mening i at installere pakker fra bookworm. I dette tilfælde skal du bestemme dig for, om du vil fortsætte eller ej. Det er muligt at nedgradere pakker, men det beskrives ikke her.
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.
Vigtigt
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.
Hvis du har foretaget ændringer, så gem filen og kør
# apt update
for at opdatere pakkelisten.
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. Fjerner forældede konfigurationsfiler
Før du opgraderer dit system til trixie, så anbefales det at fjerne gamle konfigurationsfiler (såsom *.dpkg-{new,old}-filer under /etc fra systemet.
