I've installed SELinux in Debian sid in order to use the sandbox that locks down apps to a restricted environment, but I can't get it to work. If I try to use the sandbox command in permissive mode without any options, like
sandbox nano, I get the following error:
/usr/bin/sandbox: [Errno 22] Invalid argument
And if I try to run it with options for temporary home and tmp dirs, with or without the -X option, another error message pops up:
Could not set exec context to unconfined_u:unconfined_r:sandbox_x_t:s0:c236,c539. Failed to remove directory /tmp/.sandbox-root-vfZJIt: No such file or directory
I have tried using the sandbox app in enforced mode, but it complains about missing type enforcement rules. I don't think that's the issue though. Does anyone know how to fix this?
