Ubuntu: msttcorefonts problem fixed

This is just for my own note as I have problem when installing msttcorefonts on Ubuntu Linux but anyway it is fixed, the problem is due to the wrong setting in the proxy where you can find under System -> Preferences -> Network Proxy. If you encounter the similar problem when installing other stuffs, this post may give a hint of how to fix it as well. I have been lazy to post this up but anyway here you got it -

I have encountered the problem below when installing msttcorefonts and I have tried various ways to fix(e.g. remove or fix with dpkg tool)but no luck, here's the error I got when I was trying to apt-get remove --purge msttcorefonts

Blablabla .....
dpkg: error processing msttcorefonts (--purge):
subprocess pre-removal script returned error exit status 1

All done, errors in processing 1 file(s)
dpkg: error while cleaning up:
subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
msttcorefonts
E: Sub-process /usr/bin/dpkg returned an error code (1)

I tried to search the ubuntu forum but no luck, and finally I figured I can fix by commenting these two lines in /var/lib/dpkg/info/msttcorefonts.postinst -

# db_get msttcorefonts/http_proxy
# http_proxy=$RET

Now I can do

shell>sudo apt-get remove --purge msttcorefonts

Problem fixed. Now you need to get the setting of your proxy right or just remove it to use direct connection and reinstall msttcorefonts.
