Comment 7 for bug 1878957

Hi Daniel,

From the case:

apt-mark showmanual |grep linux-

Base ISO install:

linux-base
linux-generic
linux-headers-generic

After apt upgrade:

linux-base
linux-generic
linux-headers-generic

After custom Landscape upgrade profile with autoremove:

linux-base
linux-firmware
linux-generic
linux-headers-generic
linux-image-generic

After request all upgrades from Landscape:

linux-base
linux-firmware
linux-generic
linux-headers-4.15.0-99
linux-headers-4.15.0-99-generic
linux-headers-generic
linux-image-4.15.0-99-generic
linux-image-generic
linux-modules-extra-4.15.0-99-generic

After custom Landscape upgrade profile with autoremove + security:

linux-base
linux-firmware
linux-generic
linux-headers-4.15.0-99
linux-headers-4.15.0-99-generic
linux-headers-generic
linux-image-4.15.0-99-generic
linux-image-generic
linux-modules-extra-4.15.0-99-generic

So, either "request all upgrades" or having an upgrade profile with autoremove + security, will create this issue.

Please let me know if you need more detail.
