Hi Guys,
I have installed policycoreutils-sandbox and I'm trying to open firefox in a sandbox run this command: sandbox -X -t sandbox_net_t -t sandbox_web_t -w 1920x1080 firefox
The error message:
(sandbox:8075): Gtk-WARNING **: 21:34:28.459: Theme parsing error: gtk.css:2:33: Failed to import: Error opening file /home/claudio/.config/gtk-3.0/window_decorations.css: No such file or directory
/usr/bin/firefox: line 186: getenforce: command not found
/usr/bin/firefox: line 186: [: !=: unary operator expected
Unable to init server: Could not connect: Connection refused
Error: cannot open display: :1
Any ideas?
Thanks in advance

I've found the issue preventing sandbox to work. Opening SeLinux Troubleshoot I saw that Selinux was the issue and, at the same time, found there a solution. With a few commands it is now working:
sudo setsebool -P domain_can_mmap_files 1
sudo ausearch -c 'Xephyr' --raw | audit2allow -M my-Xephyr
sudo semodule -i my-Xephyr.pp
sudo semodule -X 300 -i my-Xephyr.pp
and voila.. it works.
Hope this may help someone one day trying to run a sandbox on Fedora/SeLinux.
