Instal kernel Debian Backports secara otomatis

Saya memiliki set pin berikut:

Package: linux-image-amd64
Pin: release a=wheezy-backports
Pin-Priority: 1001

Package: *
Pin: release a=wheezy-backports
Pin-Priority: 499

Saya mendapatkan kesalahan berikut:

$ sudo apt-get install linux-image-amd64

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 linux-image-amd64 : Depends: linux-image-3.16.0-0.bpo.4-amd64 but it is not going to   be installed
E: Unable to correct problems, you have held broken packages.

Kebijakan tampaknya benar:

$ apt-cache policy linux-image-amd64
linux-image-amd64:
  Installed: 3.2+46
  Candidate: 3.16+63~bpo70+1
  Package pin: 3.16+63~bpo70+1

 *** 3.2+46 1001
        500 http://ftp.nl.debian.org/debian/ wheezy/main amd64 Packages
        100 /var/lib/dpkg/status

$ apt-cache policy linux-image-3.16.0-0.bpo.4-amd64
linux-image-3.16.0-0.bpo.4-amd64:
  Installed: (none)
  Candidate: 3.16.7-ckt4-3~bpo70+1
  Version table:
     3.16.7-ckt4-3~bpo70+1 0
        499 http://ftp.nl.debian.org/debian/ wheezy-backports/main amd64 Packages

Jadi saya tidak mendapatkan kesalahan. Apa yang saya lakukan salah?

Saya mencoba menggunakan boneka untuk memutakhirkan semua mesin Wheezy ke kernel backports (langkah reboot direncanakan), itulah sebabnya saya ingin menyelesaikannya dengan benar. Saya bisa masuk secara manual ke semua server untuk menjalankan:

sudo apt-get install -t wheezy-backports linux-image-amd64

Yang berhasil, tetapi tidak nyaman.

MEMPERBARUI

Seperti yang diminta:

/etc/apt/preferences.d$ cat linux-image 
Package: linux-image-*
Pin: release a=wheezy-backports
Pin-Priority: 1001

Package: *
Pin: release a=wheezy-backports
Pin-Priority: 499

/etc/apt/preferences.d$ sudo apt-get update

The following information may help to resolve the situation:

The following packages have unmet dependencies:

Unable to find a reason to remove linux-image-3.16.0-0.bpo.4-amd64.

Periksa apa paket itu tergantung dan apa yang dibutuhkan dependensi juga. Misalnya saya melihat ini untuk mesin saya:

#apt-cache  show linux-image-amd64
Package: linux-image-amd64
<snip>
Depends: linux-image-3.16.0-4-amd64

dan

# apt-cache  show linux-image-3.16.0-4-amd64
Package: linux-image-3.16.0-4-amd64
<snip>
Depends: kmod | module-init-tools, linux-base (>= 3~), debconf (>= 0.5) | debconf-2.0, initramfs-tools (>= 0.110~) | linux-initramfs-tool
Pre-Depends: debconf | debconf-2.0

Periksa apakah dependensi diambil dari backports juga.

sudo apt-get install -t wheezy-backports linux-image-amd64

itu tidak nyaman saya tahu .. tetapi itu adalah cara yang tepat untuk melakukan sesuatu tanpa memiliki masalah di masa depan (tentu saja IMHO)

Ubah baris teratas di preferensi Anda menjadi

Package: linux-image-*

Lari

apt-get update

Coba pasang lagi. Jika Anda masih mendapatkan kesalahan, periksa

aptitude why-not linux-image-3.16.0-0.bpo.4-amd64
