[pve-devel] DAB error: Makefile:4: die Regel für Ziel „all“ scheiterte

[Thomas]

Hello!

I have created this Makefile:
BASEDIR:=$(shell dab basedir)

all: info/init_ok
        dab bootstrap
        dab install ack
        dab install apt-forktracer apt-listchanges
        dab install byobu bzip2
        dab install dma htop iftop
        dab install logrotate nano ncdu net-tools vim
        sed -e 's/prohibit-password/yes/' -i ${BASEDIR}/etc/ssh/sshd_config
        sed -e 's/#PermitRootLogin/PermitRootLogin/' -i
${BASEDIR}/etc/ssh/sshd_config
        dab finalize

info/init_ok: dab.conf
        dab init
        touch $@

.PHONY: clean
clean:
        dab clean
        rm -f *~

When I run make it returns an error message:
