Description of problem: A lot of denials are logged on login. The audit will only show one of the applications. Removing the application will show the next on subsequent logins. Version-Release number of selected component: selinux-policy-36.6-1.fc36.noarch flatpak-selinux-1.12.7-2.fc36.noarch flatpak-1.12.7-2.fc36.x86_64 How reproducible: Always Steps to Reproduce: 1. Install `org.gnome.Extensions` from flathub 2. Reboot & login 3. sudo ausearch -i -m avc,user_avc,selinux_err,user_selinux_err -ts boot Actual results: A lot of read-denials are visible in the audit log. Expected results: No denials/audits are logged on login. ===== Audit log ===== ---- type=AVC msg=audit(16.04.2022 13:29:45.245:220) : avc: denied { read } for pid=1035 comm=dbus-daemon

There are already individual bugs open about several (all?) of these SELinux denials. While we did fix a few, there' more to go. I am going to re-purpose this bug as a tracker for all SELinux denials affecting flatpak.
This message is a reminder that Fedora Linux 36 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 36 on 2023-05-16. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 'version' of '36'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 36 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 Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle. Changing version to 39.
