I have got the following code
sudo apt-get upgrade
Which, after the download was completed, entered into a page that asks for configuration settings when I worked on a terminal , I was working with another software. I created a button that made the terminal hang up.
I closed the terminal and re-entered the code and made the following error:
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
Then I stopped it.
Now I use Ubuntu software to install another package. But it not install anything and report this error:
authentication is required to install, update, or remove packages
incorrect permissions on / usr / lib / policykit-1 / polkit-agent-helper-1 (needs to be setuid root)
I can't open the file to the path.
Also synaptic is disabled.
I have a whole set of software that I can not install over again on Ubuntu and change Ubuntu.
