Did you receive this error, “E:dpkg was interrupted, you must manually run ‘sudo –configure -a’ to correct the problem. E:_cache->open()failed,please report”?
The “dpkg” is the Debian Package manager. The automatic process has an issue and you must open up the terminal (Ctrl+Alt+t) and type in:
sudo dpkg --configure -a
Hit enter, enter your password, hit enter again, and it will run through the process to correct this.
You shouldn’t be getting this error. I am running an updated Kernal and a newer system, so that is probably why I had this issue.
