I tried installing DroidCam for my Ubuntu, and unfortunately, things went wrong. I ran `sudo apt-get install droidcam` and it failed to install. 

Whenever I try to install something else, I get:

```

dpkg: error processing package droidcam (--configure):
subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
 droidcam
E: Sub-process /usr/bin/dpkg returned an error code (1)

```

How can I fix this?
