Dear all, It seems that there is a problem stacking Devstack using the master branch. The problem happens during the step: Installing package prerequisites [ERROR] /home/vagrant/devstack/inc/python:41 Unable to find pip2.7; cannot continue This is the minimum local.conf I used: [[local|localrc]] SERVICE_HOST=192.168.10.6 HOST_IP=192.168.10.6 HOST_IP_IFACE=eth1 DATABASE_PASSWORD=secretdatabase RABBIT_PASSWORD=secretrabbit ADMIN_PASSWORD=secretadmin SERVICE_PASSWORD=secretservice LOGFILE=$DEST/logs/stack.sh.log LOGDIR=$DEST/logs LOG_COLOR=False DEST=/opt/stack USE_PYTHON3=True As a workaround I need to revert the following change, then it ends up properly: commit 279a7589b03db69fd1b85d947cd0171dacef94ee Author: Jens Harbott (frickler) <j.harbott@x-ion.de> Date: Mon Apr 16 12:08:30 2018 +0000 Revert "Do not use pip 10 or higher" This reverts commit f99d1771ba1882dfbb69186212a197edae3ef02c. Added workarounds that might want to get split into their own patch before merging: - Don't install python-psutil - Don't run peakmem_tracker Change-Id: If4fb16555e15082a4d97cffdf3cfa608a682997d Any hints? -- Best regards, *Martín Chacón Pizá* *chacon.piza@gmail.com <chacon.piza@hotmail.com>*
