Bug#1071467: linux-image-6.6.13+bpo-amd64: installation botched, tiny and corrupt deb file

[Manny <debbug.linux-amd64@sideload.33mail.com>]

Package: src:linux
Version: 6.6.13-1~bpo12+1
Severity: grave
Justification: renders package unusable
X-Debbugs-Cc: debbug.linux-amd64@sideload.33mail.com

To install linux-image-6.6.13+bpo-amd64, this command was executed:

  $ apt -t bookworm-backports install linux-image-amd64

I have a transcript of the session but it’s probably not worth
posting. It’s in the binary format produced by the “script”
command. The deb file is only 1,480 bytes, which is obviously a
non-starter. The final output was this:

  Download is performed unsandboxed as root as file '/root/linux-image-amd64_6.6.13-1~bpo12+1_amd64.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)
