[Bug 1823523] [NEW] Is bound to remove a kernel that a manually installed package depends on

[Jarno Suni]

Public bug reported:

Say, I have linux-generic-hwe-18.04 and linux-generic installed.

Software Updater may remove linux-image-4.15.0-47-generic even if
manually installed linux-generic depends on it (recursively).

$ apt-cache rdepends --important --installed --recurse linux-image-4.15.0-47-generic
linux-image-4.15.0-47-generic
Reverse Depends:
  linux-image-generic
 |linux-modules-extra-4.15.0-47-generic
linux-image-generic
Reverse Depends:
  linux-generic
  linux-generic
  linux-generic
linux-modules-extra-4.15.0-47-generic
Reverse Depends:
  linux-image-generic
linux-generic
Reverse Depends:

$ apt-mark showmanual linux-generic
linux-generic


I think it should at least disable removing such a kernel by default.
