Kill the annoying "downloading" process

If you failed at download one package in “apt-get install” commands. it’ll keep downloading it if you run “apt-get install” next time. it is really annoying.
you should kill the downloading process by check string related in the following dir or files:
“/usr/share/package-data-downloads/”
“/var/lib/update-notifier/package-data-downloads/”
“/usr/share/update-notifier/package-data-downloads-failed”
“/var/lib/update-notifier/user.d/data-downloads-failed”
“/usr/share/update-notifier/package-data-downloads-failed-permanently”
“/var/lib/update-notifier/user.d/data-downloads-failed-permanently”
and deleted the string or file related.

(Parameters) Auto mount NTFS in Ubuntu

Identy the partition table using: sudo fdisk -l
Identy the partition UUID using: sudo blkid
Add the codes below in: /etc/fstab

# change the "UUID" to your partition UUID
UUID=12102C02102CEB83 /media/windows ntfs-3g auto,users,permissions 0 0 

Make a mount point (if needed)

sudo mkdir /media/windows 

Now mount the partition

mount /media/windows 

The options I gave you, auto, will automatically mount the partition when you boot and users allows users to mount and umount .
You can then use chown and chmod on the ntfs partition.
 
or:
sudo apt-get install ntfs-config
