RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Matej Marušák 2020-06-24 08:37:43 UTC 
Description of problem:

Running 'tuned-adm recommend' on the latests rhel 8.3 nightly image (cockpit CI images [1]) fails with missing module error.

Version-Release number of selected component (if applicable):
tuned-2.14.0-1.el8.noarch

How reproducible:
`dnf install tuned` and then `tuned-adm recommend`.

Actual results:
```
  File "/usr/sbin/tuned-adm", line 26, in <module>
    import tuned.admin
  File "/usr/lib/python3.6/site-packages/tuned/admin/__init__.py", line 1, in <module>
    from .admin import *
  File "/usr/lib/python3.6/site-packages/tuned/admin/admin.py", line 9, in <module>
    from tuned.utils.profile_recommender import ProfileRecommender
  File "/usr/lib/python3.6/site-packages/tuned/utils/profile_recommender.py", line 4, in <module>
    import procfs
  File "/usr/lib/python3.6/site-packages/procfs/__init__.py", line 28, in <module>
    from .procfs import *
  File "/usr/lib/python3.6/site-packages/procfs/procfs.py", line 24, in <module>
    from utilist import bitmasklist
ModuleNotFoundError: No module named 'utilist'
```

Expected results:
Would show recommended profile.

Comment 1 Ondřej Lysoněk 2020-06-24 08:50:42 UTC 
Hi,

this is a python3-linux-procfs bug. It fails on import:
>>> import procfs
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.6/site-packages/procfs/__init__.py", line 28, in <module>
    from .procfs import *
  File "/usr/lib/python3.6/site-packages/procfs/procfs.py", line 24, in <module>
    from utilist import bitmasklist
ModuleNotFoundError: No module named 'utilist'

Version-Release number of selected component (if applicable):
python3-linux-procfs-0.6.2-1.el8.noarch
Comment 2 Ondřej Lysoněk 2020-06-24 09:36:27 UTC 
This was even caught by gating, but the failure was waived. I don't understand on what grounds. Can you explain, John?

The problematic build is python-linux-procfs-0.6.2-1.el8. The gating waiver comment for that build says 'bz1849215'. And that bug is said to be fixed in python-linux-procfs-0.6.2-1.el8, i.e. the same build. I don't get it..

Fix import of utilist

If procfs/utilist.py is not in your PYTHONPATH, the import can fail.
