So, I tried updating Sophie Cam, but I got a botched update. Apparently, I can't install the new version, because there's an old version of the .deb (presumably corrupted file) in /var/cache/apt/archives/partial/

Now, I am still a noob when it comes to Linux commands. -_- Tried deleting it with Filebox, but to no avail. Is there any terminal command that will allow me to delete file?

Tried using WinSCP to delete it, but it still won't let me.
