update and install manager not working

[amado738]

I am relatively new to linux and still struggling.

I got this message today and cant run update manager or install manager!

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

please give me a step by step guide on how I can fix this!

open up applications>accessories>Terminal, then enter in:

sudo dpkg --configure -a

that should do it

thanks it seems to have worked. what exactly caused this problem in the first place so i know what to avoid doing so it doesnt happen again?

Maybe you disconnected from your internet connection while you were downloading an update other than that I wouldn't know
also when you see a message that says manually run... copy and paste the code into terminal and hit enter that's what that notification means

Excellant advice weweboom. I wish I had known that when I first started. It is a common problem. Nice response.

Or sometimes there is a problem with the download.
