Hi, I'm trying to update a few things in a Stein cluster and while building some kolla containers, I get the following error when building the base container: INFO:kolla.common.utils.openstack-base:Step 4/8 : RUN curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py && python get-pip.py && rm get-pip.py INFO:kolla.common.utils.openstack-base: ---> Running in f5c8bb3fe6f0 INFO:kolla.common.utils.openstack-base:curl (https://bootstrap.pypa.io/get-pip.py): response: 200, time: 0.423, size: 1929903 INFO:kolla.common.utils.openstack-base:Traceback (most recent call last): INFO:kolla.common.utils.openstack-base: File "get-pip.py", line 24244, in <module> INFO:kolla.common.utils.openstack-base: INFO:kolla.common.utils.openstack-base: main() INFO:kolla.common.utils.openstack-base: File "get-pip.py", line 199, in main INFO:kolla.common.utils.openstack-base: bootstrap(tmpdir=tmpdir) INFO:kolla.common.utils.openstack-base: File "get-pip.py", line 82, in bootstrap INFO:kolla.common.utils.openstack-base: from pip._internal.cli.main import main as pip_entry_point INFO:kolla.common.utils.openstack-base: File "/tmp/tmpDXRruf/pip.zip/pip/_internal/cli/main.py", line 60 INFO:kolla.common.utils.openstack-base: sys.stderr.write(f"ERROR: {exc}") INFO:kolla.common.utils.openstack-base: INFO:kolla.common.utils.openstack-base: ^ INFO:kolla.common.utils.openstack-base:SyntaxError: invalid syntax INFO:kolla.common.utils.openstack-base: INFO:kolla.common.utils.openstack-base:Removing intermediate container f5c8bb3fe6f0 ERROR:kolla.common.utils.openstack-base:Error'd with the following message ERROR:kolla.common.utils.openstack-base:The command '/bin/sh -c curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py && python get-pip.py && rm get-pip.py' returned a non-zero code: 1 Any ideas as to where the issue is? Is this a pip installer bug? Eric
