Not able to install unity-tweak-tool in Ubuntu 14.04

Question

Installation of Unity-tweak-tool is stuck at 0% and showing nothing. I've to press CTRL+C to stop. I've checked internet connection and it is working fine.

you may try updating first sudo apt-get update && sudo apt-get install unity-tweak-tool or use a graphical manager instead, like synaptic. — Kev Inski, Jun 03 '16 at 06:39
@KevInski Didn't worked. Maybe there is some other problem. I got this at the end of update::: W: There is no public key available for the following key IDs: 1397BC53640DB551 — Bhavesh Khatnani, Jun 03 '16 at 07:20
Please post text files and program output listings as text, not as images (see How do I save terminal output to a file?). — David Foerster, Jun 05 '16 at 08:38

I have encountered the problem ever, the reason is that it use the IPv6 address to access the software repository, but I found the apt-get may can't handle the IPv6 address properly, so you should use the IPv4 address instead.

You can try sudo apt-get -o Acquire::ForceIPv4=true install unity-tweak-tool
Here are some materials about Force Apt-Get to IPv4 or IPv6 on Ubuntu or Debian

Thanks! It's installed, but I still get that message in end that no public key available. Is it fine? – Bhavesh Khatnani Jun 03 '16 at 12:32
This no public key problem may be answered in the How do I fix the GPG error "NO_PUBKEY"?, I have no idea about this, sorry. – zhenguoli Jun 03 '16 at 12:56
