Hi All! I am just more a simple with Systematp, but as I exprience, there seem alsways(?) be a problem with install .... I experienced always difficulties on Debian. Now I installed it on DEVUAN (call it a Debian without SystemD) and there is another problem with 'stap-prep', it fails (from memory) with 'rpm' not found. ----- DISTRO="$(lsb_release --id --short 2> /dev/null)" case "$DISTRO" in Debian|Ubuntu|Devuan) <== Line 182 prep_deb_based "$@" ;; ----- This is Systemtap 4.8.2 I had to add "Devuan" to that line and that does it. Just my small cooperation ;-) Regards, Manfred
