[ovirt-devel] CI fails - tox error

Hi, We experience problems with failed CI on VDSM patches. Examples: http://jenkins.ovirt.org/job/vdsm_standard-check-patch/10633/ http://jenkins.ovirt.org/job/vdsm_standard-check-patch/10634/ http://jenkins.ovirt.org/job/vdsm_standard-check-patch/10635/ This is what we see in logs: out=`tox --version`; \ if [ $? -ne 0 ]; then \ echo "Error: cannot run tox, please install tox \ 2.9.1 or later"; \ exit 1; \ fi; \ version=`echo $out | cut -d' ' -f1`; \ if python2.7 build-aux/vercmp $version 2.9.1; then \ echo "Error: tox is too old, please install tox \ 2.9.1 or later"; \ exit 1; \ fi Traceback (most recent call last): File "/usr/bin/tox", line 7, in <module> from tox import cmdline File "/usr/lib/python2.7/site-packages/tox/__init__.py", line 4, in <module> from .hookspecs import hookimpl File "/usr/lib/python2.7/site-packages/tox/hookspecs.py", line 4, in <module> from pluggy import HookimplMarker File "/usr/lib/python2.7/site-packages/pluggy/__init__.py", line 16, in <module> from .manager import PluginManager, PluginValidationError File "/usr/lib/python2.7/site-packages/pluggy/manager.py", line 6, in <module> import importlib_metadata File "/usr/lib/python2.7/site-packages/importlib_metadata/__init__.py", line 9, in <module> import zipp File "/usr/lib/python2.7/site-packages/zipp.py", line 12, in <module> import more_itertools File "/usr/lib/python2.7/site-packages/more_itertools/__init__.py", line 1, in <module> from more_itertools.more import * # noqa File "/usr/lib/python2.7/site-packages/more_itertools/more.py", line 340 def _collate(*iterables, key=lambda a: a, reverse=False): ^ SyntaxError: invalid syntax Error: cannot run tox, please install tox 2.9.1 or later make: *** [tox] Error 1 + teardown + res=2 + '[' 2 -ne 0 ']' + echo '*** err: 2' *** err: 2 + collect_logs + tar --directory /var/log --exclude 'journal/*' -czf /home/jenkins/workspace/vdsm_standard-check-patch/vdsm/exported-artifacts/mock_varlogs.tar.gz . + tar --directory /var/host_log --exclude 'journal/*' -czf /home/jenkins/workspace/vdsm_standard-check-patch/vdsm/exported-artifacts/host_varlogs.tar.gz . + teardown_storage + python2 tests/storage/userstorage.py teardown Can someone look at it?
