I just wondered if somebody could tell me what this means:  E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. reidsr@ubuntu:~$ sudo dpkg --configure -a dpkg: error: dpkg status database is locked by another process reidsr@ubuntu:~$    How do I run sudo dpkg --configure -a  manually?

Why does redirection, using sudo give me an error for the following commands?   $ sudo printf "foo" &gt;/etc/file bash: /etc/file: Permission denied  $ sudo printf "foo" ~/file; cat ~file &gt;/etc/file  bash: /etc/file: Permission denied   ...yet I have no such problem when I use an editor, or cp. I don't think I've ever tried this before, so I don't know if there is something haywire on my system, or if this is normal. It seems a bit restrictive to be normal, but(?) maybe it is intended to be restrictive...  (using Ubuntu)
