The error seems to be triggered during building initramfs. It is build in /boot. If you have much drivers used the initramfs can use more than 168M for its compression via zstd. If you can't enlarge /dev/nvme0n1p2 you could remove older kernels installed and/or limit the drivers used. Check if you have in /etc/initramfs-tools/initramfs.conf MODULES=dep BUSYBOX=auto In case they are not, change them and rebuild with update-initramfs -u -k all
