Flatpak QGIS permissions issues on installed files

[qcoles]

Hello All,

Has anyone had an issue installing Flatpak QGIS on Rhel 8 where the permissions on many directories show up with question marks in the permissions like the following:

cd /view/NightlyBuild_linux/var/lib/flatpak/runtime/org.kde.Sdk/x86_64/5.15-21.08/61a7c1ac873ecbfbdae4442a28da9d1356d105c2d6f8c9c9a719012cab99fe32/files/lib

ls -al

ls: cannot access 'os-release': Permission denied

total 136

These type files are littered throughout the directory structure above. I think the issue is because of the NIS system where those users don’t exist locally on the server. Does anyone know what the username should be or any other workaround for this type of problem?

My initial problem was the following:

Info: Could not load the Qt platform plugin "xcb" in "" even though it was found.
Fatal: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

_Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

I noticed many of the libQt5 files were owned by ?
-????????? ? ? ? ? ? libQt53DLogic.so.5.15.3
-????????? ? ? ? ? ? libQt53DQuickAnimation.prl
...
-????????? ? ? ? ? ? libQt53DQuickAnimation.so.5.15.3
-????????? ? ? ? ? ? libQt53DQuickExtras.prl

-????????? ? ? ? ? ? libQt5Designer.so.5.15.3
-????????? ? ? ? ? ? libQt5DeviceDiscoverySupport.a
-????????? ? ? ? ? ? libQt5DeviceDiscoverySupport.prl
-????????? ? ? ? ? ? libQt5EdidSupport.a
-????????? ? ? ? ? ? libQt5EdidSupport.prl
-????????? ? ? ? ? ? libQt5EglFSDeviceIntegration.prl

Any help would be appreciated.

Thanks in advance

Hi,

/view/NightlyBuild_linux/var/lib/flatpak/runtime implies some custom location where Flatpak files are being installed. Is that the case?

I ask, because I assume it's some SELinux issue with labels. You could check that by either grepping for AVC in /var/log/audit/audit.log or simply disabling SELinux with setenforce 0, just to see if it helps.

Sorry for the late response. I didn't make any configuration changes from an installation path perspective. Actually selinux is not running on this server. Update to this case. After re-installing I can no longer even get to that point where it runs and even creates that directory again. I'm getting the following error since the reinstall:

_X11 connection rejected because of wrong authentication.
Warning: could not connect to display localhost:10.0
Info: Could not load the Qt platform plugin "xcb" in "" even though it was found.
Fatal: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.
