Public bug reported:
I recently did an 24.10 install (on s390x, but I think this doesn't
matter) and was surprised that the system hangs during the post-install
reboot.
Investigation showed that this happens if the installer applies updates,
which is done by default, if there is proper network connectivity and
archive access.
In case of an install where I disabled the network, hence an offline
install was done, the installation incl. post-install reboot was
successful.
So I took such a successfully installed system (where no updates were applied)
and noticed that currently the available updates are:
$ apt list --upgradable
iproute2/oracular-updates 6.10.0-2ubuntu1 s390x [upgradable from: 6.10.0-2]
linux-generic/oracular-updates 6.11.0-9.9 s390x [upgradable from: 6.11.0-8.8]
linux-headers-generic/oracular-updates 6.11.0-9.9 s390x [upgradable from:
6.11.0-8.8]
linux-image-generic/oracular-updates 6.11.0-9.9 s390x [upgradable from:
6.11.0-8.8]
linux-libc-dev/oracular-updates 6.11.0-9.9 s390x [upgradable from: 6.11.0-8.8]
linux-tools-common/oracular-updates 6.11.0-9.9 all [upgradable from: 6.11.0-8.8]
So seemed to be kernel related, hence tried to update the kernel manually:
$ sudo apt install linux-image-generic/oracular-updates
Selected version '6.11.0-9.9' (Ubuntu:24.10/oracular-updates [s390x]) for
'linux-image-generic'

Pending kernel upgrade!
Running kernel version:
6.11.0-8-generic
Diagnostics:
The currently running kernel version is not the expected kernel version
6.11.0-9-generic.
Restarting the system to load the new kernel will not be handled automatically,
so you should consider rebooting.
Failed to check for processor microcode upgrades.
No services need to be restarted.
No containers need to be restarted.
No user sessions are running outdated binaries.
No VM guests are running outdated hypervisor (qemu) binaries on this
host.
I noticed these two lines, that have been spit out by update-initramfs:
update-initramfs: Generating /boot/initrd.img-6.11.0-9-generic
mkinitramfs: copy_file: binary '/usr/lib/udev/dmsetup_env' not found█████▋ ]
mkinitramfs: copy_file: binary '/libgcc_s.so.[1-9]' not found
Hence I tried to ran update-initramfs on the release kernel 6.11.0-8-8
and it happened there as well:
$ sudo update-initramfs -k all -u
update-initramfs: Generating /boot/initrd.img-6.11.0-8-generic
mkinitramfs: copy_file: binary '/usr/lib/udev/dmsetup_env' not found
mkinitramfs: copy_file: binary '/libgcc_s.so.[1-9]' not found

Run /lib/s390-tools/zipl_helper.device-mapper 252:1
Preparing boot device for LD-IPL: dm-0.
Done.
So it's a initramfs-tools (mkinitramfs) issue rather than a kernel issue,
somewhere in copy_libgcc() (or before).
Seems to be a small issue, but is causing a big impact, since it leads
to a broken default installation.
