check/add support for python3 + dnf on standard CI -------------------------------------------------- Key: OVIRT-723 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-723 Project: oVirt - virtualization made easy Issue Type: By-EMAIL Reporter: Yedidyah Bar David Assignee: infra Hi, Patch [1] fails jenkins [2] like this: 11:35:21 [ INFO ] DNF Repository updates-testing is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository updates-testing-debuginfo is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository updates is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository updates-debuginfo is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository fedora is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository fedora-debuginfo is listed more than once in the configuration 11:35:21 [ INFO ] DNF Downloading 1 files, 0.00KB 11:35:21 [ INFO ] DNF Downloading 1 files, 0.00KB 11:35:21 [ INFO ] DNF Failed to synchronize cache for repo 'fedora', disabling. 11:35:21 [ INFO ] DNF Failed to synchronize cache for repo 'updates', disabling. 11:35:21 [ INFO ] Stage: Environment packages setup 11:35:21 [ INFO ] DNF Repository updates-testing is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository updates-testing-debuginfo is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository updates is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository updates-debuginfo is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository fedora is listed more than once in the configuration 11:35:21 [ INFO ] DNF Repository fedora-debuginfo is listed more than once in the configuration 11:35:21 [ INFO ] DNF Downloading 1 files, 0.00KB 11:35:21 [ INFO ] DNF Downloading 1 files, 0.00KB 11:35:21 [ INFO ] DNF Failed to synchronize cache for repo 'fedora', disabling. 11:35:21 [ INFO ] DNF Failed to synchronize cache for repo 'updates', disabling. 11:35:21 [ ERROR ] DNF Cannot queue package 'iproute': no package matched 11:35:21 [ ERROR ] Failed to execute stage 'Environment packages setup': no package matched I suspected, based on the log, that something is broken about dnf configuration, so pushed [3] and ran the job again [4] with [3] cherry-picked, and it succeeded. I thought that's enough for a verification, so asked to merge it, and it was merged. Later on, lago tests started breaking [5] with: 09:37:44 Error: nothing provides repoman >= 2.0.12 needed by python-lago-ovirt-0.24.0-1.fc23.noarch So [3] was reverted [6], Currently pending, but I expect it to be merged soon. So we need a better solution. While investigating this, Nadav partially understood the issue - we have, at certain points in mock_runner, both /etc/yum.conf and /etc/yum/yum.conf. Not sure why and whether we need both. We tried also various variations on this patch in [7][8][9][10], none worked. Probably better to fully support dnf instead of this hack, not sure what this requires.
