package man-db 2.7.5-1 failed to install/upgrade: triggers looping, abandoned

[Lyubomir Bogdanov]

I have Linux PC and in the beginning (2 years ago) it was really fun to use it. Later I found out I can't perform any debugging, cookie cleaning or screen it for viruses! So I have the old version of Ubuntu and try to install the last one 17.04 when this error occurred. I am not able to perform any security test because Ubuntu is not allowing me to install and run any internet security like avast, superantyspyware, avd etc. I can't watch any videos on Youtube, because there is no way of installing adobe flash player. I will be happy if somebody can help me with this issues. Thank you!

This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'
