I installed xubuntu, after reboot it was installing updates, I stopped it by clocking the close button. Then apt-get didn't work so I removed the file
/var/lib/dpkg/lock which I don't know if I should have done. Now when I want to install something with apt-get I get
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
When I run that I get
dpkg: error: parsing file '/var/lib/dpkg/updates/0006' near line 0: newline in field name `#padding'
And I can't install anything. Help?
