Re: [rdo-dev] Rocky RPM dependency issue - pyparsing

Hi All, Kicking the t[yi]res on Rocky a bit, and I've run into an(other) RPM dependency issue. The symptom, when attempting to install openstack-keystone, is: Transaction check error: file /usr/lib/python2.7/site-packages/pyparsing.py from install of python2-pyparsing-2.1.10-3.el7.noarch conflicts with file from package pyparsing-1.5.6-9.el7.noarch ...etc.. It appears that the RPM name changed from "pyparsing" to "python2-pyparsing" somewhere along the way, and there's a kludgy empty "pyparsing" RPM that "requires" "python2-pyparsing": # rpm -qRlp /var/cache/yum/x86_64/7Server/centos7-master/packages/pyparsing-2.1.10-3.el7.noarch.rpm python-pyparsing = 2.1.10-3.el7 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(PayloadIsXz) <= 5.2-1 (contains no files) # This worked OK before because the "python-cmd2" RPM delivered in the openstack-queens repo "requires" "pyparsing": # rpm -qRp openstack-queens/python-cmd2-0.6.8-8.el7.noarch.rpm | grep parsing pyparsing >= 2.0.1 # but the version in centos7-master "requires" "python2-pyparsing": # rpm -qRp /var/cache/yum/x86_64/7Server/centos7-master/packages/python2-cmd2-0.8.8-5.el7.noarch.rpm | grep parsing python2-pyparsing >= 2.0.1 # and, unfortunately, that does not obsolete "pyparsing", so we end up with the conflict. Not sure why they didn't just have python2-pyparsing "provide" and "obsolete" "pyparsing".

This would probably not be an issue if the OS had been installed with centos7-master to begin with, but I don't think that that can be assumed - 7.5 comes with pyparsing-1.5.6-9.el7.noarch. Will openstack-rocky be delivered with a version of python2-cmd that "requires" "pyparsing", or does this need to be fixed in centos7-master, or ..... ? Seems it will need to provide something, since the pyparsing in currently-shipping el7 is too old .... ~iain
