Ubuntu

Cannot install any software

Asked by Joero

Whenever I try to install any software from Synaptic, Add/Remove, or the Sudo command, I always get this message:
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

I ran "dpkg --configure -a" and it gave me this error:
dpkg: requested operation requires superuser privilege

I have two questions:
  How may I get these superuser privileges?
  How may I get these errors to stop?

Thank you.

To get superuser privilege use sudo

sudo dpkg --configure -a

to answer question 2, simply enter the above (sudo dpkg --configure -a) into a terminal, and they will be gone.
