| Doc Text: |
When updating a Python package, pip conflicts with dnf: it removes files installed by dnf in /usr. It causes applications run by "python3 -I" to fail to import the module installed by dnf.
pip has been fixed to only install new files in /usr/local, but leave files installed by rpm in /usr/local unchanged.
For example, it is now possible to have and old version of setuptools installed by dnf in /usr, and a newer version installed by pip in /usr/local.

I tried to add / remove various SELinux related packages on my RHEL-8.0 VM, but sealert --help still works. Could you provide NVRs of SELinux related packages? # rpm -qa libsepol\* libsemanage\* libselinux\* setroubleshoot\* policycoreutils\* selinux-policy\* setools\* Hopefully, the NVRs help us to find the cause. Thanks! Do you use pip? Please see https://bugzilla.redhat.com/show_bug.cgi?id=1550368#c21 and later (In reply to Petr Lautrbach from comment #2) > Do you use pip? Please see > https://bugzilla.redhat.com/show_bug.cgi?id=1550368#c21 and later Yes, that's it. Fedora has a fix of the primary cause in https://src.fedoraproject.org/rpms/python-pip/pull-request/16 I leave it to the RHEL experts to decide if and how to fix this in RHEL. This misbehavior has a potential of destroying systems (rendering dnf/yum unusable), so I'd suggest to take it and fix this before RC. https://src.fedoraproject.org/rpms/python-pip/pull-request/10 has a previous (untested) version fo the patch applicable to pip 9. Problem summary: Upgrading a package to the latest *upstream* release using can remove the RPM-installed version, making it unusable with the rest of the system.
It can be reproduced with:
$ sudo python3 -m pip install --upgrade setuptools
$ python3 -Es -c 'import pkg_resources; print(pkg_resources.get_distribution("setools").version)'
Expected: a version number, e.g.
4.1.1
Actual result:
Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: module 'pkg_resources' has no attribute 'get_distribution'
I guess: s/using can/using sudo pip can/ Note: The fix doesn't prevent pip to remove files from /usr: # dnf install python3-pillow # ls /usr/lib64/python3.6/site-packages/PIL/version.py /usr/lib64/python3.6/site-packages/PIL/version.py # python3 -m pip uninstall Pillow Uninstalling Pillow-5.1.1: /usr/lib64/python3.6/site-packages/PIL /usr/lib64/python3.6/site-packages/Pillow-5.1.1-py3.6.egg-info Proceed (y/n)? y Successfully uninstalled Pillow-5.1.1 You are using pip version 9.0.3, however version 18.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command. # ls /usr/lib64/python3.6/site-packages/PIL/version.py ls: cannot access '/usr/lib64/python3.6/site-packages/PIL/version.py': No such file or directory I've did some testing as well, didn't notice any problems. It works fine with venv as well. The uninstallation is a known issue, we could potentially add a warning for that in a later release. python-pip-9.0.3-11.el8 is now ready for testing. See my Comment 9 for possible manual validation of the fix. 800AutoClose The change described in this bug report should be resolved in the RHEL 8.0 release. It has been closed with a resolution of CURRENTRELEASE. If the solution does not work for you, open a new bug report. *** Bug 1650327 has been marked as a duplicate of this bug. *** |
