I am getting to use Ubuntu recently.
While installing Firefox flash plugin, it took too long that I could not install another package i.e. /var/lib/dpkg/lock permission denied
I tried to interrupt the installation by remove lock file with rm -f and installed the other package
Situation turned even worse when I had to run 'sudo dpkg --configure -a' again and still it took too long so I decided to quite by Ctrl-C
Now I cannot even install any other package. The error is: "dpkg: error: parsing file '/var/lib/dpkg/updates/0011' near line 0: newline in field name `#padding'"
Why is it so troublesome with just a simple installation task?
