Error building container using apptainer built without suid

https://github.com/apptainer/apptainer/issues/2190

adnan-umich opened on Apr 27, 2024 Version of Apptainer

apptainer version 1.3.1 Expected behaviour

Since I built apptainer without requiring suid, I expected this to be build without using fakeroot. Actual behaviour

Does not build:

apptainer build –ignore-subuid –fakeroot my_container.sif test.def INFO: User not listed in /etc/subuid, trying root-mapped namespace INFO: fakeroot command not found INFO: Installing some packages may fail INFO: Starting build… INFO: Skipping GPG Key Import FATAL: While performing build: conveyor failed to get: while copying pseudo devices: while creating /tmp/build-temp-535427745/rootfs/dev/null: operation not permitted Steps to reproduce this behaviour

apptainer build –ignore-subuid –fakeroot my_container.sif test.def What OS/distro are you running

NAME=”Red Hat Enterprise Linux” VERSION=”8.6 (Ootpa)” How did you install Apptainer

From source ./mconfig –without-suid -b ./buildtree -p ${PREFIX} > ${logfile} 2>&1 Activity DrDaveD DrDaveD commented on Apr 30, 2024 DrDaveD on Apr 30, 2024 Contributor

You apparently didn’t follow the compilation instructions, because the fakeroot command is not found. That’s one of the required packages and is needed if /etc/subuid is not set up (or ignored).
