I am trying to update a process used to remaster the Ubuntu 18.04 install image for 20.04 and running into a problem with extracting the initrd archive. The command used is cpio -id --no-absolute-filenames. When I use this same command to extract the initrd image from the 20.04 image, it extracts kernel/x86/microcode/AuthenticAMD.bin and stops.

Inspecting initrd file contents I can see a "TRAILER" section showing that there are multiple archives in the file. As suggested in other threads about cpio archives, I tried to extract the compound archive as such: cat initrd | while cpio -id --no-absolute-filenames; do :; done. In this case, the first entry extracts but then it has a bunch of "0 blocks" and doesn't extract anything else.

Does anyone know how this archive was created or how to extract it?

I've looked around here and the manual pages for apt-get, apt, and dpkg. I would like to upgrade the php-fpm package without triggering an immediate restart of the service. I realize of course that a restart will be needed, I just want to be able to do it separately from the upgrade.

Use case: When upgrading packages and the kernel, the php webapp is interrupted twice, once when php-fpm is upgraded and again on reboot for the new kernel.

I have a remastered install ISO based on ubuntu-18.04-server-amd64.iso with a preseed which is failing the final step in the installer. The late_command script runs successfully, but the installer ends up on the main menu with no option to reboot.

Here is the last logs after the late_command runs:

Jul 25 19:15:36 finish-install: info: Running /usr/lib/finish-install.d/07speakup
Jul 25 19:15:36 finish-install: info: Running /usr/lib/finish-install.d/10apt-cdrom-setup
Jul 25 19:15:36 finish-install: /usr/lib/finish-install.d/10apt-cdrom-setup backed up
Jul 25 19:15:36 main-menu[289]: INFO: Menu item 'finish-install' succeeded but requested to be left unconfigured.
Jul 25 19:15:36 main-menu[289]: INFO: Falling back to the package description for cdrom-detect
Jul 25 19:15:36 main-menu[289]: INFO: Falling back to the package description for ethdetect

This seems to indicate that something in the 10apt-cdrom-setup script returned abnormally, but I see nothing in there that should fail. Any body recognize something here or have any ideas where to look?

I am remastering Ubuntu 14.04.4 ISO and preseeding. When installing some additional packages like so:

d-i pkgsel/include string openssh-server ntp curl vim-nox

vim-nox is not available, but the rest are. I have universe and other repos enabled in the preseed file like so:

d-i apt-setup/restricted boolean true
d-i apt-setup/universe boolean true
d-i apt-setup/backports boolean true
d-i apt-setup/multiverse boolean true

Is there some refresh not happening or am I missing something else?

Is there any way to know if openssl 1.0.2 now in jessie-backports will make it into trusty-backports?
