I am trying to install lustre client from the downloaded .deb file using dpkg -i command in a Ubuntu 22.04 Singularity container. The def file lustre.def is:

Bootstrap: library
From: ubuntu

%post
    apt -y update && apt -y upgrade
    apt -y install build-essential libtool pkg-config flex bison libpython3-dev libmount-dev libaio-dev libssl-dev libnl-genl-3-dev libkeyutils-dev libyaml-dev libreadline-dev module-assistant debhelper libsnmp-dev mpi-default-dev quilt swig
    wget https://downloads.whamcloud.com/public/lustre/latest-release/ubuntu2204/client/lustre-client-modules-5.15.0-88-generic_2.15.5-1_amd64.deb
    wget https://downloads.whamcloud.com/public/lustre/latest-release/ubuntu2204/client/lustre-client-utils_2.15.5-1_amd64.deb
    dpkg -i lustre-client-modules-5.15.0-88-generic_2.15.5-1_amd64.deb
    dpkg -i lustre-client-utils_2.15.5-1_amd64.deb
    rm lustre-client-*

%environment
    export LC_ALL=C

I got an error when building the container using command sudo singularity build -F --sandbox lustre lustre.def:

+ dpkg -i lustre-client-modules-5.15.0-88-generic_2.15.5-1_amd64.deb

FATAL:   While performing build: while running engine: exit status 1

The thing is, if I download the deb files and install them in normal Ubuntu 22.04, everything is ok without any problem. So, why the error /var/lib/dpkg/info/lustre-client-modules-5.15.0-88-generic.postinst: 9: depmod: not found and what I am missing in the def file? I have searched Internet but had no luck. Thank you for your help.

Solved myself.

If we run depmod in the container, it will report what is not found:

depmod: ERROR: could not open directory /lib/modules/6.8.0-47-generic: No such file or directory
depmod: FATAL: could not search modules: No such file or directory

If we shell --bind the host directory /lib/modules/6.8.0-47-generic into the container, we can install deb files using dpkg -i without any problem. So, I add

%files
    /lib/modules/6.8.0-47-generic

in the def file and the problem is solved.
