Linux Mint Title Bar is Missing - Linux Mint 17.3 Rosa

[SOLVED] Linux Mint Title Bar is Missing - Linux Mint 17.3 Rosa Cinnamon -- Okay this is not the title bar on top of application window which has the name of the app and the minimize/maximize buttons.

This is about child dialog window which can be produced when you click the about menu to show about window, save as dialog window, and etc which aren't showing up in the title bar so you can not move it to another area.

We will troubleshoot this Linux problem or may be just the setting which is not we wished before in GUI mode.

This case we produced after upgrading my Linux Mint 17.2 to Linux Mint 17.3 Rosa on Cinnamon. When I try to nemo about window it looks weird, no title bar for about window also the parent window get dimmed. You can see these picture for detail.

Okay this is not a problem, it is only incorrect setting for your Linux system. We can choose behavior preference of the title bar on the child window on Linux Mint, you can turn on the attach the child window or you can disable child window to be attached to main window.

Follow these steps to repair the missing title bar for Linux Mint 17.3 Rosa Cinnamon

Congratulation! You're done. Now you can see the title bar for your about window or save dialog of your applications. Try to open your nemo again and you will see things happened normal again.

If you prefer your child window is attached into main Window you can do the same and turn it ON.

Error Reason for Trouble downloading packages list due to a “Hash sum mismatch”

This is the race conditions, your local repo cache can get into an inconsistent state; This is a known issue, and is exacerbated for clients behind proxy caches. Some large organisations and ISPs (especially in remote parts of the world) have transparent caches of which you may not be aware.

The fundamental issue is that the apt repository format is subject to race conditions when a mirror is updated. This problem particularly affects repositories that change rapidly, such as the development release.

[SOLUTION] APT Hash Sum Mismatch

The solution for "Hash sum Mismatch" is to delete local repository and apt-get update will refresh the whole thing from source. To do this you need to execute these command from Terminal:
sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update
 
If you remove all files, you have to download them again. You can just remove the invalid file to make this process faster.
Another solution was to switch repositories (eg, from us.ubuntu.com to XX.ubuntu.com where XX is your country code) or waiting. The best idea would be to wait a bit and retry later. Removing the lists might fix broken lists, but that's rarely the case.
