7. Managing your bookworm system before the upgrade

Šiame priede pateikiama informacija apie tai, kaip įsitikinti, kad galite įdiegti ar atnaujinti bookworm paketus prieš atnaujinant iki trixie.

7.1. Sistemos bookworm atnaujinimas

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.

Jei atnaujinate iš Debian’o serverio-veidrodžio, tai automatiškai bus atliktas atnaujinimas paskutiniosios bookworm laidos.

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.

Jei jau įdiegėte paketus iš trixie, tai nebėra daug prasmės įdiegti paketus iš bookworm. Tokiu atveju turite nuspręsti patys, ar norite tęsti, ar ne. Grįžti prie senų paketų naudojimo įmanoma, bet čia apie tai nekalbėsime.

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.

Svarbu

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.

Jei atlikote kokius nors pakeitimus, išsaugokite failą ir vykdykite komandą

# apt update

tam, kad būtų atnaujintas paketų sąrašas.

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.
