I updated to 4.3.1 and this came up when I tried to SSH.

Code:
Command 'groups'
failed with return code 127 and error message
-sh: line 30: groups: command not found.
I updated to 4.3.1 and this came up when I tried to SSH. It goes into the device find but I can't use the terminal. It gives me this error:

Code:
/$ dpkg --set-selections < cydia-backup; dselect
dpkg: status database area is locked by another process
Error opening terminal: unknown.
Anyway I can fix this error? Thank you
