Package: apt
Version: 3.1.11
Severity: normal
X-Debbugs-Cc: [email protected]

Dear Maintainer,

Since 2.5.2, apt would upgrade binary packages of the same source 
package together. As an example, `apt install linux-image-amd64` would 
update linux-headers-amd64 and a few others as well. I've been using 
this as a workaround for #1109062, #1085722 (apt-listchanges sending the 
entire several-megabyte history of the linux package whenever the kernel 
is upgraded).

Since the default solver switched to 3.0, this behaviour is no longer 
there: `apt install linux-image-amd64` updates the linux-image only.

    # apt install linux-image-amd64 --solver internal
    Upgrading:
       libcpupower1 (6.16.12-2 => 6.17.6-1)
       linux-cpupower (6.16.12-2 => 6.17.6-1)
       linux-headers-amd64 (6.16.12-2 => 6.17.6-1)
       linux-image-amd64 (6.16.12-2 => 6.17.6-1)
       linux-libc-dev (6.16.12-2 => 6.17.6-1)
       linux-perf (6.16.12-2 => 6.17.6-1)

    Installing dependencies:
       cpp-15-for-host (15.2.0-7)
       gcc-15-for-host (15.2.0-7)
       linux-headers-6.17.6+deb14-amd64 (6.17.6-1)
       linux-headers-6.17.6+deb14-common (6.17.6-1)
       linux-image-6.17.6+deb14-amd64 (6.17.6-1)
       linux-kbuild-6.17.6+deb14 (6.17.6-1)

vs.

    # apt install linux-image-amd64 --solver 3.0
    Upgrading:
       linux-image-amd64 (6.16.12-2 => 6.17.6-1)
