YaST2 error: (gnomesu): CRITICAL **: There are no services for 'libgnomesu' available.

This document (7000691) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server and Desktop

Situation

When running YaST2 either from the GNOME or KDE panel or in a shell using the command 'yast2' the following error is experienced

** (gnomesu:7186): CRITICAL **: There are no services for 'libgnomesu' available.

Resolution

Solution

Create /etc/permissions.local and state the permissions for the files that need to be adjusted.

Create /etc/permissions.local with an editor
State access permissions within the file in the following way:
FILE (including full path) USER:GROUP PERMISSIONS, e.g.
```
/usr/lib/libgnomesu/gnomesu-pam-backend  root:root 4755
```
Save the file
Run the command

chkstat --system

to activate the changes.

Alternative solution

Lower the file permissions to mode 'secure' or 'easy' with YaST2.

Cause

This issue is caused by wrong access permissions of the file /usr/lib/libgnomesu/gnomesu-pam-backend. These are usually set to '-rwsr-xr-x' (note the 's' for SUID) or 4755 but in case the file permission have been altered or set to mode 'paranoid' using the YaST2 security module, the new settings will be '-rwxr-xr-x' or 0755.

Additional Information

Permissions stated in /etc/permissions.local are used for all security levels. If a certain permission should only be set when the system is in a special permissions mode, files in /etc/permissions.d/ are more suitable. Create them with a name like foo.paranoid and the settings will only be used when the system is set to have 'paranoid' file permissions. Same is valid for easy, local or secure mode.
