is content in /var/lib/ucf/cache safe to delete?

I'm not sure if the contents in /var/lib/ucf/cache are safe to delete, but I found unused file which I already removed using

Code:

apt remove --auto-remove

, which I dont know why it does not completely remove the related file. there still some debris left.

It depends. Some files are safe to delete and others, you may well need. Generally, it can be safely said that deleting all the contents of a cache folder in root can cause a headache if not careful.
As long as you are removing an installation you no longer want and you have checked that it is not integrated with essential software, you should be fine with using Synaptic to remove or using terminal commands to remove.
Sometimes the "--remove purge" command can remove leftover files.

Files are often left behind and the reason for it seems to be: Many people uninstall and then re-install. By leaving some configuration files, it makes a faster and more stable reinstallation of software.

When I am feeling lazy... I just use "Ubuntu Cleaner" tool to tidy up once in a while. It is basic, thorough and easy to use. There are many Cleaning Tools out there, like BleachBit. You can use Synaptic if you have it installed (Click Status tab, then click Residual Configuration files, select what you want to remove, select apply). But I recommend avoiding GtkOrphan. It can easily wipe out your OS if a misclick happens.
