:
:*****  Plugin catchall_labels (83.8 confidence) suggests  ********************
:
:If you want to allow gnome-shell to have execute access on the tucan.py file
:Then you need to change the label on /usr/share/tucan-0.3.10/tucan.py
:Do
:# semanage fcontext -a -t FILE_TYPE '/usr/share/tucan-0.3.10/tucan.py'
:where FILE_TYPE is one of the following: updpwd_exec_t, xdm_tmp_t, chkpwd_exec_t, hostname_exec_t, gkeyringd_exec_t, lib_t, init_exec_t, ld_so_t, shutdown_exec_t, abrt_helper_exec_t, alsa_exec_t, consoletype_exec_t, textrel_shlib_t, xdm_exec_t, policykit_auth_exec_t, pam_console_exec_t, bin_t, lib_t, etc_t, xserver_exec_t, dbusd_exec_t, loadkeys_exec_t, plymouth_exec_t, xauth_exec_t, ssh_agent_exec_t, mount_exec_t, shell_exec_t, rpm_exec_t, pulseaudio_exec_t, oddjob_mkhomedir_exec_t, pam_exec_t, systemd_systemctl_exec_t, fusermount_exec_t, xsession_exec_t, systemd_systemctl_exec_t. 
:Then execute: 
:restorecon -v '/usr/share/tucan-0.3.10/tucan.py'
:
:
:*****  Plugin catchall (17.1 confidence) suggests  ***************************
:
:If you believe that gnome-shell should be allowed execute access on the tucan.py file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep gnome-shell /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
