This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: ======================= When I insert a USB or CD/DVD the Xfce file manager (Thunar) won't show the removable device in the side panel. There are no errors or SELinux alerts. To troubleshoot I tried 'udisksctl status' which failed and that triggered an alert. See steps below for details.

Steps to Reproduce: =================== 1. Confirm that SELinux is in 'enforcing' mode. 2. Open an Xfce session. 3. Start Thunar. 4. Insert a USB/CD/DVD media. 5. Run: udisksctl status 6. Switch SELinux to permissive. 7. Repeat step 5. 8. Log out. 9. Kill all processes for the user account (I do it by switching to a console screen and login as 'root' the 'pkill -9 -U <user>') 10. Login as user. 11. Open Thunar. 12. Insert a removable media. 13. Remove media. 14. Switch SELinux to 'enforcing'. 15. Insert media. 16. Repeat step 5. Actual results: =============== 4. Media is not displayed in the side panel. No SELinux alerts. 5.

Media will be displayed in the side panel. 13. Media item will be removed from the side panel. 15. Media is not displayed in the side panel. No SELinux alerts. 16. Same error as in step 5. No SELinux alerts. Expected results: ================= No errors and Thunar functional when SELinux is enforced. Additional info: ================ I turned off 'dontaudit' and repeated steps 12, 13 and 16. The results are: 12 & 13: I.
