Hello, in my first post i have to ask a lot

when i open xterm throws this:

BusyBox v1.10.2 (Debian 3:1.10.2.legal-1osso30+0m5) built-in shell (ash)
Enter 'help' for a list of built-in commands.

-sh: /home/user/.bashrc: line 5: cannot create /dev/cgroup/cpu/user/6152/tasks: nonexistent directory
-sh: /home/user/.bashrc: line 5: cannot create /dev/cgroup/cpu/user/6152/notify_on_release: nonexistent directory
~ $


and when i try to apt-get install something it gives me a big error log:

home/user # apt-get install slingshot
