** Description changed: [Impact] When running kernel version 4.4.0-78 (for example) and the unattended-upgrade packages installs a new kernel 4.4.0-79 (for example) the linux-cloud-tools-4.4.0-78 and linux-cloud-tools-4.4.0-78-generic packages are removed by the Remove-Unused-Dependencies rule, because unlike "normal" kernel packages they are not excluded by /etc/apt/apt.conf.d/01autoremove-kernels. The linux-cloud-tools package has the hyper-v integration services daemons in it, so it's deletion leaves some of the integration not working. Could /etc/apt/apt.conf.d/01autoremove-kernels be updated so other hyper-v users aren't caught out by this? Thanks, Ian. - [Test case] + [Test case (apt)] Make sure that linux-cloud-tools for protected kernels are listed in APT::NeverAutoRemove, for example, on cosmic: - "^linux-cloud-tools-4\.17\.0-9-generic$"; - "^linux-cloud-tools-4\.18\.0-7-generic$"; + "^linux-cloud-tools-4\.17\.0-9-generic$"; + "^linux-cloud-tools-4\.18\.0-7-generic$"; Those are in 01autoremove-kernels + [Test case (unattended-upgrades)] + + * Check the running kernel and install relevant cloud-tools packages: + # uname -a + Linux x-uu-lp-1737637 4.15.0-39-generic #42-Ubuntu SMP Tue Oct 23 15:48:01 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux + root@x-uu-lp-1737637:~# apt-cache search 4.15.0-39-generic + linux-cloud-tools-4.15.0-39-generic - Linux kernel version specific cloud tools for version 4.15.0-39 + linux-headers-4.15.0-39-generic - Linux kernel headers for version 4.15.0 on 64 bit x86 SMP + linux-image-4.15.0-39-generic - Signed kernel image generic + linux-image-unsigned-4.15.0-39-generic - Linux kernel image for version 4.15.0 on 64 bit x86 SMP + linux-modules-4.15.0-39-generic - Linux kernel extra modules for version 4.15.0 on 64 bit x86 SMP + linux-modules-extra-4.15.0-39-generic - Linux kernel extra modules for version 4.15.0 on 64 bit x86 SMP + # apt install linux-cloud-tools-4.15.0-39-generic + Reading package lists...
