This bug is similar to BZ#1845618 (RHEL-8), but there are additional SELinux denials. This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle. Changing version to 34. I've submitted a Fedora PR to address the issue: https://github.com/fedora-selinux/selinux-policy/pull/893 FEDORA-2021-a15b7e7314 has been submitted as an update to Fedora 34. https://bodhi.fedoraproject.org/updates/FEDORA-2021-a15b7e7314 FEDORA-2021-a15b7e7314 has been pushed to the Fedora 34 testing repository. Soon you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --advisory=FEDORA-2021-a15b7e7314` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2021-a15b7e7314 See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates. FEDORA-2021-a15b7e7314 has been pushed to the Fedora 34 stable repository. If problem still persists, please make note of it in this bug report. |
