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.

Comment 1 Miro Hrončok 2021-02-25 10:21:27 UTC 
pip-uninstalling rpm-installed packages should not work, that is expected.

The error message is cryptic, we have opened https://github.com/pypa/pip/issues/8954 already.
Comment 2 Li, Jin 2021-03-01 02:00:45 UTC 
Hi Miro

In my opinion, the issue here is that if the custom migrate from RHEL8 to RHEL9, when the custom's environment need chardet < 4.0 (specified by requirement in python project), the installation will fail in RHEL9 while it works well on RHEL8. I do not think it is acceptable.
Comment 3 Miro Hrončok 2021-03-01 09:31:36 UTC 
> I do not think it is acceptable.

I respectfully disagree. If this was not acceptable, we would not be bale to update any Python package ever and we would be stuck with the RHEL 8 versions for eternity.

If a customer specifies Python requirements in projects, such as "chardet < 4.0", they can use PyPI (or their internal package server) to fetch and install the packages into a virtual Python environment. RHEL offers only a very limited set of packages in a very limited set of versions (usually one version per package for a specific Python version).

Uninstalling system packages with pip and replacing them with custom versions isn't (and never was) a supported use case. In fact, users can brick their system when they do that.

Before we go any further: What **exactly** do you try to accomplish here? I don't think uninstalling chardet is the end goal here, is it?
Comment 4 Li, Jin 2021-03-05 07:55:06 UTC 
Hi Miro,

Actually i can create a virtual env to install the pip package chardet, just a little curious about the system behavior change from RHEL8 to RHEL9. Feel free to close this bug since there's been a pip issue to track the log problem. Thanks for your explanation

Upstream PR: https://github.com/pypa/pip/pull/9949

Let's wait a bit for their feedback before we backport it.
Comment 6 Petr Viktorin (pviktori) 2021-06-16 12:28:36 UTC 
It was merged upstream, so we can backport (or rebase after release)
Comment 7 Petr Viktorin (pviktori) 2021-06-16 12:30:54 UTC 
It should first go in Fedora Rawhide and 34.
