按照从 Wheezy 迁移到 Jessie 的说明，我更新了我的源apt-get update;apt-get upgrade;apt-get dist-upgrade（不是一次更新，但足以检查一切正常），并重新启动了我的 VPS。
我开始着手从 php5 切换到 php7，删除 php 包，突然我发现这种情况开始发生，通过每个 apt：
The following packages will be REMOVED:
linux-image-2.6.32-5-amd64
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
1 not fully installed or removed.
After this operation, 104 MB disk space will be freed.
Do you want to continue? [Y/n]

E: Sub-process /usr/bin/dpkg returned an error code (1)
我试着按住它，希望 apt 会忽略它，因为我似乎对此无能为力，但我得到了
E: Can't find a source to download version '2.6.32-48squeeze6' of 'linux-image-2.6.32-5-amd64:amd64'
据我所知，有问题的软件包尚未安装。
答案1
dpkg --purge --force-remove-reinstreq linux-image-2.6.32-5-amd64
这将从系统中清除该包。问题已解决。
